Créer son branding avec l'IA : méthodes et prompts (ChatGPT, Gemini & Claude)

Summary: Creating Your Branding with AI in 2026

AI allows for rapid exploration of brand essence, tone of voice, manifesto, and brand keywords. Used with the right prompts and data, it accelerates certain branding steps. However, it does not replace strategic analysis, real market knowledge, or the ability to create a unique brand emotion. This article presents comprehensive prompts for each branding step, in the correct order, and precisely explains AI's limitations. Graphic design is the stage where AI systematically fails. At Wiiv, a branding and packaging agency based in Paris, operating in Bordeaux, Lyon, and Milan, we perform all these steps humanly, and we deliver an AI-ready brandbook designed to be 100% exploited by AI afterward.

Creating Your Branding with AI: Methods, Prompts, and Limitations

Before starting, initialize your AI with specific prompts that define its role and working mode. These initialization prompts (and all others) are available in the free downloadable AI-ready brandbook. Without this initialization, the AI starts from scratch with each session. With it, it keeps track of previous work and maintains consistency.

Everyone has tried. Some were amazed. They entered some information into ChatGPT, got a positioning in two minutes, asked Midjourney for a logo, and thought that branding, after all, wasn't so complicated.

Then they saw the result in the market.

At Wiiv, we tested it. We created brands from A to Z with AI. The result was visually correct. Clean, even. But looking at it, you felt exactly this: nothing. No emotion, no point of view, no reason to prefer this brand over another.

Our recommendation is clear: all these steps should be done with human intelligence. Not because AI cannot produce something. But because what it produces is almost always generic on the decisions that truly matter. If you want to understand how we perform these steps at Wiiv and how we deliver a result designed to be used by AI daily, visit our AI branding page.

But if you want to create your branding 100% with AI, here are all the prompts, in the correct order. Each step has several: AI never produces the right result in a single prompt. You need to iterate. Expect between 3 and 5 cycles to get something usable.

"At Wiiv, we prefer to leave brand strategy and the major branding steps to human intelligence, then adapt them so that AI can use them. But if you want to create your branding strategy 100% with AI, here are the steps and prompts."

Philippe, Co-founder of Wiiv

The Golden Rule Before Starting: AI Is Only as Good as What You Give It

AI doesn't know your brand. It doesn't know your market. It doesn't know your actual target. It knows the average of millions of content pieces in markets that are not yours. What you feed it in the following prompts determines the quality of what it produces. If you give it vague information, it produces vague answers. If you give it precise information rooted in a real understanding of your market, it can produce useful starting points.

That's why all the prompts in this article have blanks to fill in. These blanks are not optional. They are the information you need to know before you start. And if you don't know them, it's not an AI problem. It's a brand strategy problem that AI cannot solve for you.

The Tools: ChatGPT, Claude, and Gemini

ChatGPT is the most versatile for writing tasks and brand content generation. It excels in tone of voice, manifestos, and keywords. Its strength lies in language fluidity and its ability to iterate quickly on specific feedback.

Claude is particularly effective for tasks requiring nuance, precision, and structured analysis. It is the tool of choice for working on brand essence, operational values, and communication guidelines. Claude Cowork allows you to create a persistent project where you upload all your brand documents: brandbook, guidelines, analyses, personas. With each new session, Claude already knows the context. This is the most efficient way to use AI in a long-term branding project.

Gemini adds an extra dimension: its connection to real-time information allows cross-referencing brand outputs with current trend data. Useful for verifying that a semantic territory is not already saturated. Use with caution and verification: AI can invent trends that do not exist.

All the prompts in this article work with all three tools. Use the one you are already proficient with. Consistency of use matters more than tool choice.

Complete Method: Creating Your Branding with AI Step-by-Step

The order of the steps is not arbitrary. Each step feeds the next. Naming comes last, not first: you cannot choose a good name without knowing what the brand truly is. Start there.

Step 1: The Founder Analysis

A brand is an extension of its founder. Their true motivations, not the ones they would give in an interview. This is the most uncomfortable and important step. AI will challenge you. Answer honestly.

The main limit is here. Founders are rarely aware of their true motivations. It's after a few hours of workshops that they discover what truly drives them, and that changes the entire brand. Philippe

You are a brand strategy expert. You will help me analyze my founder profile to build the foundations of my brand. Ask me these questions one by one and wait for my answer before moving to the next:

1. Why are you truly creating this brand? Not the LinkedIn version. The real reason.
2. In ten years, if this brand succeeds perfectly, what does your life look like?
3. What do you categorically refuse to do to sell, even if it would be profitable?
4. What do you know better than most people in your market?

Once I have answered all questions, summarize in three paragraphs: my true motivations, my operational red lines, and the strengths of my personality that the brand should embody.

Here are my answers to the questions about my founder profile: [PASTE YOUR ANSWERS]

Now challenge me:
1. Identify contradictions between what I say I want and what my answers truly reveal.
2. Tell me if my motivations are distinctive enough to establish a differentiating brand, or if they resemble those of any founder in the same sector.Be direct. It's only useful if it's honest.

Step 2: The Real Target

This is the stage where most founders lie to themselves the most. There's almost always a gap between the imagined target and the one that actually pulls out their credit card. This gap changes everything. AI will reveal it if you give it the right information.

You are a brand strategy and consumer psychology expert. I will describe my target as I imagine it. Your role is to challenge this description to help me find the real target (the one who actually buys) and not the ideal target (the one I'd like to have).

My target as I describe it: [YOUR COMPLETE DESCRIPTION]
My product: [DESCRIPTION]
My price: [PRICE]
My direct competitors: [LIST]
Customer reviews I have already received (if available): [VERBATIMS]

Analyze:
1. Which elements of my target description seem based on my desires rather than real data?
2. How likely is it that my real target is different from my stated target? Based on what indicators?
3. Propose an alternative psychographic portrait of my real target, based on available signals.
4. What information am I missing to validate or invalidate my current target?

Here are [20 TO 30 CUSTOMER REVIEWS] of my main competitor in my sector [SECTOR]. These reviews come from [SOURCE: Google / Trustpilot / Amazon].

Analyze these reviews and answer these three questions:
1. What are the recurring emotional frustrations that this brand fails to address, beyond functional issues?
2. What unspoken needs consistently emerge between the lines?
3. Who are these buyers really: describe their psychographic profile based on their words, not socio-demographic categories.

These frustrations are my opportunity area. Formulate them as unoccupied brand spaces that I could claim.

Based on all we have analyzed, write the complete portrait of my real target in four sections:
1. Who she truly is (lifestyle, values, purchase context, relationship with money and quality)
2. What she seeks beyond the product (the emotional or identity benefit)
3. What builds her trust in a brand like mine
4. What drives her away (visual codes, tone of voice, or promises that repel her)

This portrait must be precise enough that if I show an Instagram post to someone who matches this profile, they will immediately recognize themselves.

Step 3: Brand Essence (Why, Mission, How)

This is the heart of the brand. The Why: why it exists beyond the product. The Mission: what it commits to accomplishing. The How: the distinctive way it does it. This is the most strategic element. Everything else follows from it.

You are a brand strategy expert. Help me formulate the brand essence of an e-commerce brand in the [SECTOR] sector.

Context:
- What the founder deeply believes about their market: [FOUNDER'S CONVICTION]
- The concrete problem the brand solves: [TARGET'S REAL PROBLEM]
- The distinctive way the brand solves it: [WHAT DIFFERENTIATES THE APPROACH]
- What the brand commits never to do: [RED LINE]
- The target: [PRECISE PROFILE OF THE ACTUAL BUYER]

Formulate:
1. The Why (why this brand exists beyond its product, 1 to 2 jargon-free sentences)
2. The Mission (what the brand commits to concretely accomplishing for its target)
3. The How (the distinctive way it fulfills this mission)

Each element must be specific to this brand. If it can apply to any other brand in the same sector, rephrase until it is distinctive. Propose 3 different versions of each element.

Here is the brand essence I have chosen:
Why: [YOUR WHY]
Mission: [YOUR MISSION]
How: [YOUR HOW]

Challenge it on three points:
1. Substitutability test: Could this Why belong to three of my competitors without modification? If so, rephrase until it is unique to my brand.
2. Consistency test: Does the Mission logically follow from the Why? Is the How truly distinctive or is it a polite way of saying "we do our job well"?
3. Target test: Does this brand essence truly speak to my real target or the one I'd like to have?
Deliver a corrected final version of each element.

Step 4: The Brand Promise

The explicit and verifiable commitment to the buyer. A promise that applies to any brand in the same sector is not a promise. It is a statement of intent without differentiating value.

Based on the following brand essence:
Why: [YOUR WHY]
Mission: [YOUR MISSION]
Target: [YOUR TARGET PROFILE]

Generate 5 formulations of brand promise. Each promise must be:
- Precise and verifiable (not "the best product" but "a measurable result in X")
- Systematically kept at every touchpoint
- Impossible for most competitors to keep (otherwise it's not a differentiating promise)

For each promise, specify: how the buyer can verify that it is kept, and which close competitor could not make the same promise without lying.

Step 5: Operational Values

Not just words on a wall. Principles of decision-making. Each value must answer two questions: what does it concretely forbid? What does it concretely impose? A value that forbids nothing and imposes nothing is not a value.

Help me define my brand's operational values. These values are not inspiring words. They are decision-making principles that filter every action of the brand.

Context:
- Brand essence: [YOUR WHY + MISSION + HOW]
- What the brand refuses to do: [YOUR RED LINES]
- What differentiates the brand's approach: [YOUR HOW]

Generate 5 operational values. For each value:
1. The name of the value (1 to 3 words)
2. Its operational definition (what it concretely imposes and forbids)
3. An example of a decision that this value imposes in the brand's daily life
4. An example of a decision that this value forbids even if it would be profitable in the short term

Here are my 5 operational values: [YOUR VALUES WITH THEIR DEFINITIONS]

Test them against these three concrete scenarios to verify that they are not just decorative:
Scenario 1: An influencer with 500k followers offers you a highly paid partnership, but its content is on the edge of your values. What do your values say?
Scenario 2: A very unhappy client posts an aggressive negative review publicly. What do your values say about how to respond?
Scenario 3: You can increase your margins by 20% by changing an ingredient or material that clients will probably not notice. What do your values say?
If your values do not provide a clear and distinct answer to these scenarios, they are not operational enough. Rephrase.

Step 6: Tone of Voice

How the brand speaks, not what it says. Allowed words, forbidden words, how the register varies according to context. The list of forbidden words is often the most useful: it creates safeguards applicable by any service provider without constant supervision.

You are a brand communication strategy expert. Help me define the tone of voice for an e-commerce brand in the [SECTOR] sector.

Context:
- Positioning: [IN ONE PRECISE SENTENCE]
- Target: [DETAILED PROFILE: who she is, how she speaks, what she reads, what she rejects]
- Values: [YOUR 5 OPERATIONAL VALUES]
- 3 adjectives that perfectly describe the brand's personality: [ADJECTIVE 1 / ADJECTIVE 2 / ADJECTIVE 3]
- 3 adjectives the brand should never be: [ADJECTIVE 1 / ADJECTIVE 2 / ADJECTIVE 3]

Produce:
1. Description of the tone of voice in 3 paragraphs (what it is, what it is not, how it varies depending on the context: social media / customer service / email / packaging)
2. List of 15 words the brand readily uses with an explanatory sentence for each
3. List of 15 words the brand never uses with an explanatory sentence for each
4. The level of formality (tutoiement/vouvoiement) depending on the medium and why

Based on the defined tone of voice, write these 5 examples in the brand's exact register:
1. A 60-word product description for [PRODUCT NAME]
2. A response to a negative public comment on Instagram (the comment: "[COMMENT TEXT]")
3. A welcome email hook (first email post-purchase, do not sell)
4. A 10-word advertising hook for Meta Ads
5. A customer service response to an aggressively requested return

For each example, mandatory verification: could this text belong to a direct competitor? If so, rephrase until it is distinctly within the brand's territory.

Step 7: The Tagline

The synthesis in a few words of what the brand promises, to whom, and why it's different. If it could belong to three competitors without modification, the positioning is not precise enough.

Based on the following brand elements:
Why: [YOUR WHY]
Target: [YOUR TARGET PROFILE]
Positioning: [WHAT DIFFERENTIATES YOU]
Tone of voice: [TONE DESCRIPTION]

Generate 10 taglines. Each tagline must:
- Say something specific about this brand (not a generic industry promise)
- Be understandable in 3 seconds
- Resist the substitutability test: impossible for a direct competitor to use without lying

For each tagline: a sentence about what it says to the target and what it doesn't say. And a score out of 10 on its differentiating strength with justification. Immediately eliminate taglines below 7.

Step 8: The Brand Manifesto

The most human text in the brandbook. It does not sell. It declares. It must be able to be read aloud and recognized as belonging only to this brand. AI can produce a good first draft here, provided it has access to all the context built in the previous steps.

You are an expert in brand writing. Help me write the manifesto for an e-commerce brand. This manifesto should sound like a declaration, not a sales pitch. It should be read aloud and recognizable as belonging to this brand and no other.

Here is the full context:
- Name: [BRAND NAME]
- Sector: [SECTOR]
- Why: [THE WHY]
- Mission: [THE MISSION]
- Values: [VALUES WITH THEIR DEFINITIONS]
- Promise: [THE PROMISE]
- Target: [DETAILED PROFILE]
- Keywords: [LIST]
- Forbidden words: [LIST]
- Tone of voice: [DESCRIPTION]
- What this brand thinks of its sector: [STRONG OPINION]

Write a manifesto of 150 to 250 words. No bullet points. No commercial title. An assertive, direct, memorable voice. If a sentence can apply to any other brand in the same sector, delete it and rephrase. Propose 2 versions: one more assertive and direct, one more poetic and emotional.

Here is the chosen manifesto: [YOUR MANIFESTO]

Analyze it on three axes:
1. Read it aloud. Which sentences sound false, too marketing, or too generic? List them and propose rephrasing.
2. Recognition test: if I remove the brand name, can someone who knows it guess which brand it is? If not, what is missing to make it more distinctive?
3. Emotion test: what precise emotion does this manifesto evoke? Is it the desired emotion according to the brand essence? Deliver a final version.

Step 9: Brand Keywords

Once everything else is determined, AI is perfect for finding and generating ideas for keywords. Philippe

You are an expert in brand strategy and semantics. Help me define the semantic territory of an e-commerce brand in the [SECTOR] sector.

Context:
- Positioning: [IN ONE SENTENCE]
- Target: [PROFILE]
- Values: [LIST]
- Manifesto: [YOUR MANIFESTO]
- Words already overused in this sector to avoid: [LIST: e.g., "natural", "authentic", "passion", "quality"]

Produce:
1. 20 keywords the brand owns (organized into 3 groups: rational / emotional / aspirational)
2. 10 words never to use because they are too generic or oversaturated in this sector
3. 3 distinctive lexical fields the brand can explore that are not yet saturated

For each keyword: a sentence explaining why this word belongs to this brand and not to its competitors.

Here are my chosen keywords: [YOUR LIST]

Verify them on two axes:
1. Load these words into Google Trends or analyze them with your data: which are on the rise, which are plateauing, which are declining in my sector [SECTOR] in the [FRANCE / EUROPE] market?
2. For each word, tell me how many of my main competitors ([COMPETITOR LIST]) already systematically use it. A word used by more than 3 competitors is no longer differentiating.

Step 10: Market Reverse Prompting

Very rarely used, reverse prompting is an incredibly effective method in all areas of branding and marketing strategy. But you have to know how to use and analyze it. Philippe - Wiiv

Reverse prompting reverses the usual logic. Instead of asking AI to create, we ask it to analyze. And that's where it becomes really useful in branding. You submit existing content (customer reviews, founder's posts, comments on competitors) and ask it to extract the emotional DNA.

Here are my [10 TO 15] latest posts on [LINKEDIN / INSTAGRAM]: [PASTE POSTS]

Analyze these texts and answer:
1. What deep convictions about my market emerge from these texts, even implicitly?
2. What is my true natural tone of voice (not the one I want to have, but the one I really have)?
3. What topics do I clearly avoid? What does that say about my blind spots?
4. Formulate my implicit Why from these posts. Is it consistent with what I declared in my brand brief?

Step 11: The Graphic Charter

Warning: this is the stage where Wiiv does not validate the use of AI. Visual generation tools (Midjourney, Firefly, DALL-E) are trained on what already exists. They reproduce the visual codes of the sector with great precision. Too great. The result is aesthetically correct and strategically predictable. To create a distinctive visual territory, you must know how to intentionally transgress the codes of the sector. And AI cannot do that. It can help you explore. It cannot decide what will be distinctive. The risk is to obtain a generic identity that resembles all competitors, which is precisely the opposite of good branding.

The following prompts can help you explore visual directions. But use them as a starting point to fuel human reflection, not as final decisions.

Brand identity mood board for [BRAND NAME], [SECTOR] brand targeting [TARGET DESCRIPTION IN ENGLISH].

Visual territory: [ex. raw and minimal / warm and organic / clean and clinical / bold and graphic]
Color mood: [ex. deep earth tones / crisp whites and blacks / warm terracotta and sage]
Emotional register: [ex. quiet confidence / joyful precision / sensory warmth]
Avoid: [WHAT IS SATURATED IN THE SECTOR: e.g., pastel pink / Scandinavian minimalism / kraft paper aesthetic]
Competitors to visually differentiate from: [BRANDS WE DON'T WANT TO BE CLOSE TO]
Style: editorial brand mood board, lifestyle aesthetic --ar 3:2 --style raw

Note: these prompts work best in English for both tools.

Without generating images, help me define the visual strategy for my brand [NAME] in the [SECTOR] sector.

Brand essence: [WHY + MISSION + HOW]
Target: [PROFILE]
Positioning: [IN ONE SENTENCE]
Values: [LIST]

Define:
1. The 3 dominant visual codes of the sector that my brand must absolutely avoid to differentiate itself
2. The visual territories available in this sector (not yet saturated)
3. The compositional rules that would translate my values into visuals (density, space, symmetry, rupture)
4. Visual references to explore outside my sector (architecture, fashion, art, industrial design) that match my positioning
Justify each recommendation based on the brand essence.

Step 12: Packaging Information Hierarchy

According to our tests, AI is currently unable to create packaging that differentiates, makes you want to buy, or creates a true brand identity, but if you want to start the reflection process, here's a useful prompt.

You are an expert in packaging strategy and consumer psychology. Help me define the optimal information hierarchy for packaging in the [SECTOR] sector.

Product: [PRECISE DESCRIPTION]
Target: [DETAILED PROFILE]
Purchase context: [PHYSICAL SHELF / E-COMMERCE / BOTH]
Main promise: [IN ONE SENTENCE]
Price: [PRICE] in a market where competition is between [RANGE]

Define:
1. What should stand out in less than 2 seconds on the main face (1 single priority element)
2. What comes in a second reading on the main face
3. What the secondary faces should say and in what order
4. How to integrate mandatory mentions without overshadowing the main promise
5. E-commerce specificity: how does this hierarchy hold up at 80 pixels wide in a miniature thumbnail?

Step 13: Naming (last)

Naming is clearly not an element where you should let AI choose, but if it can help you in your reflection, here's a useful prompt.

Naming comes last because a good name can only be chosen after defining its real target, its precise positioning, its brand essence, and its tone of voice. A name chosen before these steps is chosen by intuition. And the founder's intuition about naming is almost always biased.

You are an expert in brand strategy and naming. I will give you the complete context of my brand built during Deepbranding. Use all this context to generate name proposals consistent with the strategy.

Full context:
- Sector: [PRECISE SECTOR]
- Real target: [COMPLETE PSYCHOGRAPHIC PROFILE]
- Positioning: [WHAT DIFFERENTIATES]
- Brand essence (Why + Mission + How): [FULL TEXT]
- Values: [LIST]
- Emotional territory: [THE CENTRAL EMOTION]
- Tone of voice: [DESCRIPTION]
- Competitors to avoid visually and phonetically: [LIST]
- Semantic universes to avoid (saturated in the sector): [LIST]
- Geographic market: [FRANCE / EUROPE / INTERNATIONAL]

Generate 20 name proposals in 4 categories:
1. Evocative (emotional or sensory association without describing)
2. Invented (new words with no pre-existing meaning, registrable)
3. Hybrid (real word repurposed or combination of two words)
4. Founder or territory (rooted in a person or place)
For each name: why it is consistent with the brand essence, what it says to the target, and any potential risk.

Among the proposals, here is my feedback:
- [NAME 1]: I like [WHAT I LIKE] but not [WHAT I DON'T LIKE]
- [NAME 2]: interesting direction but I'm looking for something more [ADJECTIVE]
- What I no longer want to see: [UNIVERSE, SOUNDS TO ELIMINATE]
- What I want to explore further: [PRECISE DIRECTION]

Generate 15 new names taking this feedback into account. Do not reuse any previous names. This cycle repeats 3 to 5 times.

I have selected these candidate names: [LIST OF 5 NAMES]

For each, analyze:
1. Memorability (1 to 10 with justification): is it remembered after a single exposure?
2. Distinctiveness in the [SECTOR] sector (1 to 10): risk of confusion with a competitor?
3. International: meaning in the languages of the target markets ([LANGUAGES]), potential negative connotations, phonetic proximity to inappropriate words
4. Adaptability: does it work across a range, for sub-brands, in different markets?
5. Theoretical availability: what is the risk that it is already registered with INPI or on social media?
Final verdict for each name: keep for legal verification, explore, or eliminate.

Step 14: The Final Stress Test

The worst test to do after all this: ask AI if your brand is generic and bland. 80% chance it will say yes, even though the initial brief was to differentiate. This is where AI leaves us perplexed: it can tell you it's not good, but it still does it. Philippe

You are an expert in brand auditing. Here are the complete elements of my branding:

- Naming: [NAME]
- Tagline: [TAGLINE]
- Positioning: [IN ONE SENTENCE]
- Why: [THE WHY]
- Manifesto: [THE COMPLETE MANIFESTO]
- Values: [LIST WITH DEFINITIONS]
- Tone of voice: [DESCRIPTION]
- Real target: [DETAILED PROFILE]

Answer these four questions:
1. Identify 3 major contradictions between these elements (e.g., a name too technical for a very poetic manifesto, values that contradict positioning)
2. Is the manifesto's promise supported by the operational values listed?
3. Rate from 1 to 10 the strength of the link between the complete verbal identity and the real target. If below 8, explain precisely what needs to be realigned.
4. Could this complete branding belong to a direct competitor? Identify the least distinctive element and propose a rephrasing.
Be direct. If something doesn't hold up, say it clearly.

The Wiiv Approach: Human First, AI Ready

You now have all the prompts to create your branding from A to Z with AI. But here's what these prompts cannot do, regardless of the quality of the information you give them.

They cannot analyze your real market with eyes that have seen dozens of similar markets. They cannot identify your true target if you give them your imagined target rather than the real one. They cannot create a singular brand emotion because they optimize towards the statistical average. And they cannot decide what will be distinctive in your sector because they reason from what exists, not from what is missing.

What Wiiv does differently: we perform all these steps manually, based on a method proven across dozens of product brands. Then we deliver two documents: the strategic brand book (for humans and service providers) and the AI-ready brand book (designed to be ingested by an AI). This document enables Claude, ChatGPT, or Gemini to produce content in the right tone, for the right target audience, with the right words, without constant re-briefing.

Specifically, a well-constructed AI-ready brand book allows for generating consistent content across all channels (social media, customer service, emails, ads, product descriptions, creative briefs), maintaining consistency as the team grows, feeding the AI daily without re-explaining the brand's identity in each session, and quickly opening or closing a partnership opportunity by asking the AI if it aligns with the brand's territory.

To understand how we build this system, Wiiv's AI branding page details the complete approach. And if you want to download the AI-ready brand book template to start structuring your document, it is available for free on this page.

"Once you've done all this work, even with AI, you have a foundation for reflection, new ideas, and inspirations. And that's exactly where we can work together to build the best possible identity for your brand. Come back to us with what you've built, and we'll look together at what holds up and what we can make truly distinctive."

Philippe, co-founder of Wiiv

The Real Limitations of AI in Branding

AI produces plausible, not distinctive, content. It optimizes toward the average of what already exists. In a market where everyone uses the same tools with the same prompts, the result tends toward even greater uniformity than before. Standing out from the generic requires a strong stance, a deep understanding of what is oversaturated and what is available, and the ability to embrace it. AI cannot make these choices for you.

AI doesn't know your real target audience. It works with what you give it. If you give it your imaginary target, it validates it. If you give it your real target, it can feed it. But identifying the difference between the two is a market analysis job that AI cannot replace.

AI can invent non-existent trends. It can confidently state that a color is "trendy in 2026 in the food sector" when it's either inventing it or extrapolating from outdated data. Never use AI as a primary source for market trends without independent verification.
