As of 13 August 2026, AI can create a brand style guide for your business.
Most people should do this themselves; the prompt is on this page.

What the alternative costsThe available tool data does not give a price for a human brand strategist or design service.
If this goes wrong: your materials look inconsistent or generic until you correct the guide and update the affected assets.
What to actually do
Do it yourself
The route this page recommends
A chat interface, chat-fluent skill, and roughly 30 minutes until you can act on the result.
How to actually do it
- Open a document or notes file and gather your current website copy, approved marketing messages, logo files, colour codes, font names, image rules and examples of materials that already sound right.
- Write down your business name, what you sell, target audience, positioning, brand personality, values, main channels and any competitors or tones you want to avoid.
- Paste the prompt into ChatGPT, Claude or Gemini, replace each bracketed slot with your information, and attach or paste the relevant brand material.
- Ask the model to produce the guide and to separate confirmed rules, recommendations, contradictions and decisions still needed.
- Compare every factual statement, colour, font, logo rule and approved phrase in the draft against your existing files and delete anything unsupported.
- Read the voice examples aloud against real customer communications, then change the rules that do not sound like your business or suit your audience.
- Copy the approved guide into your working document, add the final logo and visual examples, and send it to the people who create your website, emails and marketing materials.
Prompt
Create a practical brand style guide for [BUSINESS NAME] using only the information and assets I provide below. Do not invent facts, customers, values, colours, fonts, claims or brand history. If something is missing, label it as a decision I need to make. Business information: - What we sell: [DESCRIPTION] - Target audience: [AUDIENCE] - Positioning and main difference: [POSITIONING] - Brand personality: [PERSONALITY] - Values: [VALUES] - Main competitors or brands whose tone we want to avoid: [COMPETITORS OR NONE] - Main channels: [WEBSITE, EMAIL, SOCIAL MEDIA, PRINT, OTHER] Existing brand material: [PASTE WEBSITE COPY, APPROVED MESSAGES, COLOUR CODES, FONT NAMES, LOGO RULES, EXAMPLES OF GOOD COPY AND ANY OTHER SOURCE MATERIAL HERE] Produce a clear guide with these sections: 1. Purpose and audience 2. Brand positioning and key messages 3. Voice and tone, including do and do-not examples 4. Writing rules, including plain-English guidance 5. Approved terminology and words to avoid 6. Visual identity, using only supplied colour and font information 7. Logo and image-use rules, marking any missing rules for my decision 8. Channel adaptations for each supplied channel 9. Three example applications based only on the supplied facts 10. A short checklist for anyone using the guide Separate confirmed rules from recommendations. Flag contradictions in the source material. Keep the language specific and usable by a small UK business. Do not claim that the guide is legally compliant or that any wording is exclusive to us. End with a list of decisions and missing assets I must resolve before publishing.
Open it prefilled in ChatGPT or Claude, or copy it into Gemini, which takes no prefill link.

What it gets wrong
- It cannot decide what your business should stand for when your positioning and audience are unclear.
- It produces plausible brand language that may sound distinctive without being distinctive in your market.
- It cannot reliably judge whether the visual system works across your actual logo files, templates, screens and print materials without those materials being supplied and checked.
- It does not know which claims, names or visual assets you have permission to use, so you must check ownership and approvals.
- It cannot make the final taste decision about whether the guide feels like your business rather than a tidy generic template.
Even on a YES, the friction has a name: taste, context depth and judgement under ambiguity.

FAQ
- Can ChatGPT create a brand style guide?
- Yes. It can structure your brand information and draft rules for voice, tone, terminology, colours, fonts and common channels. It cannot choose a convincing brand strategy from a vague brief, so supply approved material and make the final decisions yourself.
- What should I give AI to create a brand style guide?
- Give it your positioning, audience, values, personality, existing website copy, approved messages, logo rules, colour codes, font names and examples of writing that already works. Also state what is undecided, because the model will otherwise fill gaps with generic recommendations.
- Can AI choose my brand colours and fonts?
- It can suggest options and explain how to document them, but a suggestion is not a finished visual identity. You need to check the choices against your existing logo, customer-facing materials, accessibility needs and the way the brand appears in your actual channels.
- Is an AI-made brand style guide good enough to use?
- It can be good enough for an internal first version or a small business with clear existing branding. Before publishing, check every factual and visual rule, test the examples in real materials and resolve the decisions the guide marks as missing.
