Summary: How to create a brand book and what it should really contain
A brand book is a brand's permanent strategic guide. In the age of AI, it has become the best tool for using ChatGPT, Claude, Gemini, and similar as AI marketing tools. The brand book defines who the brand is, who it speaks to, what it promises, how it expresses itself, and how it presents itself. It serves both to make the right strategic decisions and to produce consistent content daily (especially with AI). A good brand book covers eleven elements: founder analysis, real target audience, tagline, brand essence, promise, manifesto, operational values, tone of voice, keywords, visual guidelines, and marketing levers. Wiiv is a strategic branding and packaging agency based in Paris, operating in Bordeaux, Lyon, and Milan, specializing in e-commerce brands in the food, cosmetics, fashion, and lifestyle sectors. This article explains how to create a useful brand book, not a decorative PDF that gets archived two weeks after delivery.
Key points: a brand book is not a graphic charter. It cannot be created without prior strategic work. It must be usable by any service provider without supervision. Its real value is measured by the quality of the decisions it enables, not by its number of pages.
How to create a brand book: what it should really contain
Everyone should have a brand book. But no one ever opens it anyway.
Not because the founders aren't interested. But because most brand books are built to impress, not to be used. They are too long, too technical, too reserved for specialists. They end up in a Dropbox folder that you accidentally find six months later while looking for something else.
A failed brand book doesn't just cost money. It costs consistency. Every decision made without this reference document is a decision made on intuition, on the whim of the moment, without a guiding principle. And that's precisely what the brand book was supposed to prevent.
This article exists to show what a truly useful brand book is, what it should contain, what it should not contain, and how to build it in the right order.
"We are sometimes brought brand books created by other agencies. Beautiful, often. 80 pages, well laid out, moodboards everywhere. And when we ask the founder what they actually use from it daily, the answer is always the same: the colors and fonts. The rest, they don't know what it's for. That's exactly what a brand book should not be."
Philippe, co-founder of Wiiv
Why a brand book is now mandatory for working with AI
The results obtained with AI are particularly linked to the information provided to it. Today, many brands already use AI daily to create content, make decisions, and write emails, but based on... not much.
In the age of AI, the brand book provides a working basis for AI, allowing it to be the perfect brand ambassador: the tone, the approach, the messages, the ideas, the strategy. Everything is aligned with you, with your brand.
Without it, it's like asking a stranger to work for your brand after giving them 2 or 3 pieces of information – it's unlikely they'll have the right/best answers for you.
What a brand book really is
A brand book is your brand's strategic guide. Not a graphic charter. Not a portfolio. Not a document produced to show that you've "done the work".
It's what provides direction and guidelines. What allows you to know if a decision is consistent with what the brand is. What dictates what an Instagram post, packaging, product photo, customer service email, or comment response should look like. What guides both aesthetic and strategic choices.
The simplest test to know if a brand book is good: can a service provider who doesn't know the brand work within its identity without bothering you? If the answer is no, the brand book is not finished.
A well-constructed brand book is also what you reread when you've forgotten why you started. When daily life has taken over vision. When you no longer know if a decision is consistent with what you initially wanted to build. It's the document that brings you back to course, without needing to rethink everything.
Why most brand books are useless
Three main reasons. First: they are too complex to be distributed to the entire team. A document that an art director understands but a freelance community manager cannot apply is a half-useful document.
Second: they are not part of daily work habits. A brand book that is consulted once upon delivery and then archived is not a tool. It's a deliverable. The difference is fundamental. A tool is opened regularly. It is consulted before making a decision. It is shared with new arrivals. It is used to evaluate whether an opportunity is consistent with the brand's identity.
Third: they contain too many useless things and not enough concrete things. Moodboards that are useless once the design is finished. Pixel-perfect spacing rules that no one respects. Logo variations that no one will ever use. And not enough real application examples, not enough verbal rules, not enough concrete cases that show what to do and what not to do.
The result is predictable: the brand book is archived two weeks after delivery. And the brand continues to operate on intuition.
Before the brand book: the work you can't skip
A brand book is a deliverable. It is not a starting point. It documents strategic decisions that have already been made. If these decisions have not been made, the brand book cannot invent them. And if you try to do so anyway, you get exactly the kind of generic document that AI produces in two minutes.
What must exist before creating the brand book: a serious analysis of the founder and their vision, an analysis of the market and competition, a precise definition of the actual target (not the imagined one), and a differentiating positioning rooted in market reality. These elements are not found in a brief filled out in fifteen minutes. They are built through a structured work process.
This is precisely the role of Deepbranding at Wiiv: to create the strategic foundations on which the brand book will rest. Without these foundations, the brand book is a beautiful presentation of emptiness.
The distinction between launch vs. redesign: the content of the brand book remains the same in both cases. What changes is the process. For a launch, everything is built from scratch with a blank slate. For a redesign, you start by analyzing what exists, understanding why it no longer works, and deciding what to keep. The reflection is different. The final deliverable covers the same elements.
The 11 elements of a complete brand book
1. Founder Analysis
This is the most underestimated element. And by far the one that most often makes the difference between a brand that lasts and one that goes in all directions.
Too many brands fail because of a poor understanding founders have of themselves. They think they know what they want to build. But what they project, their true motivations, their risk areas, their real skills and those they overestimate, all of this influences every brand decision. Often without them being aware of it.
The work on the founder explores: their deep motivation, not the one they give in interviews, but the one that truly made them get up one morning to launch this brand. Their long-term vision. What they are truly good at and what they will need to delegate. What they want this brand to be in ten years. These elements are not decorative. They structure everything that follows.
2. The Real Target
Not the target you imagine. The one that actually buys. The difference is almost always present, and it changes everything: the perceived price level, the visual codes that build trust, the copywriting register, the priority sales channels.
One example that comes up too often: founders who describe their target as "high-income earners." This is the ideal target for only 20% of brands. The remaining 80% use this target because it seems the most ambitious, the most serious, the most reassuring in a pitch. Not because it corresponds to their market reality. A brand book built on an imaginary target is a brand book that leads in the wrong direction.
3. The Tagline
The synthesis in a few words of what the brand promises, to whom, and why it's different. It functions as a positioning test: if it cannot be formulated distinctively, then the positioning is not yet clear enough. It forces precision. It forces decisions.
4. The Brand Essence: Why, Mission, How
The heart of the brand. Why it exists beyond its product (the Why). What it commits to achieving concretely for its target (the Mission). The distinctive way it fulfills this mission (the How). These three elements form the backbone of all subsequent decisions. Every design, communication, and distribution choice must be tested against them.
5. The Brand Promise
The explicit commitment the brand makes to its buyer. Precise, verifiable, systematically kept. A promise that applies to any brand in the same sector is not a promise. It is a generic statement. The promise informs packaging, copywriting, customer service, and product development. It is a permanent operational filter.
6. The Manifesto
The most human text in the brand book. The brand's voice in its freest and most assertive form. It doesn't sell. It declares. It serves internally to align teams, externally for PR, in investor pitches to establish the emotional vision before the numbers.
7. Operational Values
Not words on a wall. Decision-making principles. Each value must answer two questions: what does it prohibit? What does it require? A value that prohibits nothing and requires nothing is not a value. It's a pleasant adjective. In the brand book, each value is accompanied by its precise definition in the context of the brand and concrete examples of what it means in daily life.
8. The Tone of Voice
How the brand speaks, not what it says. A list of words it readily uses, a list of words it never uses, and the context in which the tone varies depending on the medium. The list of forbidden words is often the most useful: it creates guardrails applicable by any service provider without needing supervision.
9. Brand Keywords
The terms the brand appropriates within its category. Those that define its semantic territory, which recur in all its content with enough regularity to create an association in the buyer's mind. They inform product naming, copywriting, article titles, hashtags, and video scripts.
10. Visual Guidelines
This is an appendix to the Wiiv brand book, not its core. It covers: logo variations and their usage rules, the color palette with exact codes, the typographic system, composition rules, and especially real application examples on relevant media. Not generic mockups. Visuals that show exactly what the brand should be in real life. For example, the work done for Kera illustrates how a visual direction radically different from market norms can create immediate and memorable differentiation.
11. Marketing Levers and Action Recommendations
This point is specific to Wiiv: it is not always part of the brand book in the strict sense, because it is immediate and not long-term. But our founders always leave knowing what to do concretely. Priority communication channels. The first actions to launch. The trade-offs to make in the following weeks. The concrete, not the theory. This is a commitment we make on every project.
What a brand book should not contain
A brand book is only valuable if it is used. And what prevents it from being used is often what is included unnecessarily.
Moodboards. A moodboard is an internal reflection step, not a final deliverable. It is used to explore creative directions during the project. Once decisions are made, it has no place in the brand book. What to put instead: concrete visual examples of the finished brand, in a real situation, showing exactly what the identity should be in real life.
Competitive analysis tables. Useful during the strategic phase. Useless in the final deliverable. Knowing that competitor A uses blue and competitor B uses a serif says nothing about how to apply your own brand's identity daily.
Obsessive spacing and grid rules. How many pixels between the logo and the page edge. Millimeter-precise exclusion zones. These rules exist in the identity manuals of large corporations. For a growing e-commerce brand, no one respects them, no one checks them. What defines the brand is the consistency of colors and the constancy of tone, not the number of pixels between two elements.
Unusable logo variations. The gradient version, the 3D version, the animated version without precise instructions. These variations clutter the document and create confusion about what is allowed or not.
In general: anything a non-specialist doesn't understand. A brand book must be readable and applicable by the founder, their community manager, their photographer, and their Shopify developer. If a section requires expertise to be understood, it has no place in this document.
The difference between a brand book and a graphic charter
This is the most frequent confusion, and it explains many poorly framed projects from the outset.
A graphic charter covers the visual rules of the identity: logo, colors, typography, layout. It is a production tool. It tells how to apply the identity. It does not say why these choices were made, nor who they speak to, nor what they should communicate.
A brand book covers strategy, meaning, and visual and verbal rules together. It explains why the brand is what it is, who it speaks to, what it promises, how it expresses itself, and how it presents itself. The graphic charter is a consequence of the brand book, not its equivalent.
Having a charter without a brand book is like having an instruction manual without a building. You know how to lay bricks. You don't know what you're building or why.
In what order to create them: always the brand book first. The graphic charter comes next, as a visual translation of the strategic decisions made in the brand book. If you're wondering what this investment represents, our guide on branding quotes details what each step actually costs and why prices vary so much.
Format, length, and updates
A Wiiv brand book ranges from 20 to 90 pages, depending on the project's complexity. It's not a matter of volume. It's a matter of useful density. Each page must answer a question that a real user will ask themselves during their work week. If a page doesn't answer any practical question, it has no place.
Regarding the format: we deliver in PDF. This is the document the founder keeps with them, rereads, and transmits. It's the book they fall asleep with. We're considering a Notion version in parallel to make the brand book more alive, more editable, and more easily updated over time. Both have their value. The PDF as a permanent reference. Notion as a daily work tool.
Regarding updates: a brand book is not set in stone. It evolves with the brand. But it is not entirely rewritten with every change. The strategic foundations (brand essence, values, promise) are stable. Visual guidelines and marketing levers can be updated more regularly. Best practice: revise the brand book at each significant life stage of the brand, such as a major new product, a new market, a change in positioning, and not every season.
Who should have access to the brand book: everyone in the brand's ecosystem. The founder, the internal team, regular service providers, new hires. It is the first document shared with a new entrant. And it is what ensures that the brand remains consistent even when the founder is not in the loop of every decision. If you want to understand what such an investment represents and how to spread it over time, our complete guide on branding quotes helps you frame the budget.
"One of our clients called us a year after the brand book was delivered. He told us he had almost made a strategic decision that would have completely contradicted what we had built together. By rereading the brand book, he rediscovered the vision he had at the beginning, the one that daily life had made him forget. And he made the right decision. That's why we insist so much that the brand book must be a living document, not an archived deliverable."

Brand book and AI: 7 prompts to leverage your knowledge base
If you were wondering, no, AI cannot produce a good brand book for you, and I invite you to read this to find out why. Philippe
Once your brand book is built, it becomes your brand knowledge base. And this is where AI becomes truly useful: not for creating on your behalf, but for producing based on what you have defined.
The method is simple. You upload your brand book to Claude, ChatGPT, or Gemini. You use one of the following prompts as the opening message of the conversation. The AI works within the framework of your brand, not in a vacuum.
Two rules before starting. First: the more precise your brand book, the better the outputs. AI fed with a solid brand book produces consistent content. AI fed with a vague brand book produces generalities. Second: these prompts do not replace judgment. They accelerate production. Final validation remains human.
Prompt 1: Post Generator
When to use it: you need to produce content for social networks and you want to make sure you stay within the brand territory, without drifting towards a generic or promotional tone. Ideal for briefing a community manager or generating a bank of editorial ideas.
You will play the role of editorial director for this brand. I am uploading its complete brand book. Read it entirely before answering anything.
Once read, confirm to me:
- The tone of voice you understood in 3 adjectives
- The target audience you identified in one sentence
- The editorial territory you will respect
Only then, generate 10 post ideas for [INSTAGRAM / LINKEDIN / TIKTOK]. For each idea:
- A hook (first line that stops the scroll)
- The body of the post in a maximum of [X] words
- An angle that is not promotional but reinforces the brand territory
Never start a post with the brand name. Never use the following words: [LIST OF WORDS TO AVOID FROM THE TONE OF VOICE]
Prompt 2: Product Naming
When to use it: you are launching a new product and you want a name consistent with your existing brand identity, without breaking or contradicting what is already on sale. Particularly useful for range extensions.
You will help me name a new product while remaining 100% consistent with this brand's identity. I am uploading its brand book. Read it entirely.
The new product: [PRECISE DESCRIPTION OF THE PRODUCT, ITS FUNCTION, WHAT IT PROVIDES]
It fits into the existing range: [YES/NO + DETAILS]
Name length constraint: [SHORT / 1-2 WORDS / FREE]
Language: [FRENCH / ENGLISH / BILINGUAL]
Generate 15 name proposals organized into 3 groups:
- Names in direct continuity with the existing territory
- Names that extend the territory without betraying it
- More daring names that could open a new chapter
For each name: a sentence explaining why it is consistent with the brand book, and a sentence about what it says to the target audience.
Prompt 3: Creative Shooting Brief
When to use it: you are preparing a photo or video shoot and you need to brief a photographer, art director, or production agency. This prompt generates a complete, ready-to-share document that avoids back-and-forth and ensures the result will be within the brand's universe.
You will generate a complete creative brief for a photo or video shoot for this brand. I am uploading its brand book. Read it entirely.
Shooting context:
- Objective: [PRODUCT LAUNCH / SOCIAL MEDIA CAMPAIGN / LOOKBOOK / WEB PAGE]
- Final medium: [INSTAGRAM / WEBSITE / PACKAGING / OTHER]
- Indicative budget: [MODEST / MEDIUM / AMBITIOUS]
- Planned location: [STUDIO / OUTDOOR / AT HOME / FREE]
Generate a structured creative brief that covers:
1. The general atmosphere in 3 visual references to look for (describe them, do not name them by brand)
2. The typical casting profile (age, style, energy)
3. The dominant color palette to respect
4. Props and accessories consistent with the universe
5. What should never be seen in this shooting
6. 3 key framing or composition intentions
7. The emotion someone should feel when seeing these visuals without knowing the brand
Prompt 4: Product Description
When to use it: you need to write product descriptions for your Shopify store, Amazon listings, or launch posts. This prompt generates three versions adapted to different formats, all in the brand's exact tone of voice. Also useful for briefing an external copywriter.
You will write product descriptions for this brand. I am uploading its brand book. Read it entirely before writing a single line.
Product to describe: [PRODUCT NAME]
What it concretely does: [FUNCTION]
What it emotionally provides: [PERCEIVED BENEFIT]
Mandatory mentions to include: [KEY INGREDIENTS / LABELS / OTHER]
Write 3 versions in the exact tone of voice of the brand:
- Short version (40 words max): for Instagram or product button
- Medium version (100 words): for Shopify product page
- Long version (200 words): for collection page or storytelling
Absolute rules:
- Never start with the product name
- Never use the words: [FORBIDDEN WORDS FROM THE BRAND BOOK]
- The main promise must appear in the first 10 words of each version
Prompt 5: Negative Comment Response
When to use it: you receive a difficult comment on social media or a review platform and you don't know how to respond without betraying the brand's identity. This prompt ensures that the response stays in tone, neither too defensive nor too subservient, and that it preserves the customer relationship.
You will help me respond to a difficult customer comment while perfectly staying within this brand's identity. I am uploading its brand book. Read it entirely.
Here is the comment received: [PASTE THE EXACT COMMENT]
Context:
- Platform: [INSTAGRAM / GOOGLE / TRUSTPILOT / OTHER]
- The comment is: [WELL-FOUNDED / PARTIALLY WELL-FOUNDED / UNFAIR / AGGRESSIVE]
- What we can concretely offer: [REFUND / EXCHANGE / EXPLANATION / NOTHING CONCRETE]
Generate 3 response versions:
- A short and firm version (for an aggressive comment)
- An empathetic and restorative version (for a real problem)
- A version that turns criticism into conversation
For each version: respect the tone of voice of the brand book, never be subservient, apologize only if justified, and always end with an opening, not a closing.
Prompt 6: Quick Pitch
When to use it: you are preparing a meeting with a distributor, investor, journalist, or potential partner. This prompt generates an oral pitch calibrated for the interlocutor, with probable objections and answers to prepare. Also useful for preparing an initial contact email.
You will help me build an oral pitch for this brand for [A DISTRIBUTOR / AN INVESTOR / A PARTNER / A JOURNALIST]. I am uploading its brand book. Read it entirely.
Pitch context:
- Duration: [30 SECONDS / 2 MINUTES / 5 MINUTES]
- Format: [IN-PERSON ORAL / VIDEO CONFERENCE / FOLLOW-UP EMAIL]
- What I want the interlocutor to remember: [ONE SPECIFIC THING]
- What I want them to do afterwards: [SCHEDULE A MEETING / REFERENCE / INVEST / COVER]
Generate the pitch strictly respecting:
- The tone of voice and keywords of the brand book
- The brand promise as a guiding thread
- An opening hook that does not start with "Hello, I am..." or "Our brand is..."
- A closing with a precise call to action
Also provide me with: the 3 most probable objections from this interlocutor and a short answer for each, consistent with the brand's positioning.
Prompt 7: Customer Service Response Assistant
When to use it: you need to respond to a complex customer request, manage a return or complaint, and you want the response to be in line with the brand's identity. This prompt is also useful for building a database of standard customer service responses to integrate into an FAQ or a tool like Gorgias.
You will play the role of customer service assistant for this brand. I am uploading its brand book. Read it entirely. You will respond to customer requests strictly respecting the tone of voice, values, and posture of this brand.
Here is the customer request: [PASTE THE EXACT MESSAGE]
Request type: [RETURN / REFUND / QUALITY COMPLAINT / PRODUCT QUESTION / DELIVERY DELAY / OTHER]
The actual situation is: [WHAT WE CAN DO / WHAT WE CANNOT DO / WHAT WE DON'T KNOW YET]
Generate a response that:
- Opens with an acknowledgment of the problem (without excessive apologies if not justified)
- Provides a solution or a clear next step
- Stays in the exact brand tone (neither too formal nor too familiar according to the brand book)
- Never promises what cannot be delivered
- Ends with a sentence that preserves the long-term customer relationship
Also suggest a "standard response" version that could be integrated into an FAQ or a customer service response database.
How to know if your brand book is good
Three simple tests, none of which require branding expertise.
The external provider test. Give your brand book to someone who doesn't know your brand, like a freelance graphic designer, photographer, or writer. Ask them to produce something for you based solely on this document. If the result is consistent with your identity without you needing to explain anything, the brand book is good. If you have to correct, explain, or adjust, the brand book is incomplete.
The founder test. Can you explain your brand book in 5 minutes to an investor without having reread it? Are the key elements sufficiently ingrained to guide a difficult decision when it arises? If you have to reread it entirely to remember what it says, then its content is not yet sufficiently integrated into the brand's culture.
The time test. Is it still relevant 18 months after its creation? Does the defined target still correspond to those who buy? Do the operational values still guide real decisions? A good brand book ages well because it is built on solid strategic foundations, not on fleeting visual trends.
Frequently asked questions about the brand book
Does Wiiv provide an AI-ready branding book?
Yes, at wiiv, we provide a special AI-ready brand book format. Ready to be uploaded to any AI and optimized to give all the necessary information to your favorite AI. And yes, it works with your favorite AI: ChatGPT, Claude, Gemini, Perplexity, etc.
What is the difference between a brand book and a graphic charter?
A graphic charter covers the visual rules of identity: logo, colors, typography. A brand book covers the complete strategy: who the brand is, who it speaks to, what it promises, how it expresses itself verbally and visually. The charter is an annex to the brand book, not its equivalent. Having a charter without a brand book is like having an instruction manual without knowing what you are building.
How many pages should a brand book be?
Between 20 and 90 pages depending on the complexity of the project. It's not a question of volume, it's a question of useful density. Each page should answer a practical question that a real user will ask. A well-constructed 90-page brand book is better than a 40-page brand book filled with mood boards and spacing rules that no one reads.
Who should create the brand book?
A brand strategy agency, not a graphic designer. The brand book requires market analysis, competitive review, work on the founder and their vision, and the ability to make decisive strategic decisions. It is not a layout exercise. It is an exercise in strategic precision.
Can you create your brand book with AI?
Partially. AI can help explore certain steps: naming, tone of voice, manifesto, keywords. It cannot replace the strategic analysis of the real market, the identification of the true target, or the decisive positioning statement. A 100% AI brand book will be generic. The blanks to fill in the prompts of this article represent exactly the information that AI cannot invent for you.
How long does it take to create a brand book?
Between 2 weeks for a light launch and 3 months for a complex brand reorientation with several product lines. The duration depends directly on the depth of the strategic work upstream. A brand book produced in 48 hours is a brand book that has not done this work.
When should you redo your brand book?
At each significant stage of the brand's life. New market, new positioning, major new range, fundraising, change of direction. Not every season, not every trend. Strategic foundations are stable. It is the variations that evolve. A well-constructed brand book from the start minimizes the frequency of deep redesigns.
How to use your brand book with AI daily?
By uploading it as a knowledge base to Claude, ChatGPT, or Gemini, and by using structured prompts that ask the AI to produce within the brand's framework. The 7 prompts in this article cover the most frequent use cases: posts, product naming, creative brief, product descriptions, comment responses, pitch, and customer service. The more precise the brand book, the better the outputs.
Does Wiiv deliver a brand book in all its projects?
Yes. At Wiiv, a branding and packaging agency based in Paris with operations in Bordeaux, Lyon, and Milan, every project begins with Deepbranding, the strategic process that precedes any visual decision. The brand book is the main deliverable of this phase. It then serves as the foundation for all subsequent design, packaging, and Shopify development work.
