Paste 3-5 pieces of content you love that sound most like YOU: your best email, social post, website copy, or even a voice message transcript. The AI extracts the voice from what already works.
How to use this prompt
- Pick your AI model. Choose the tab for Claude, ChatGPT, Gemini or Copilot. Each variant is tuned for that model.
- Copy the full prompt. Click Copy Full Prompt to copy the text to your clipboard.
- Paste into your AI tool. Open your chosen model and paste the prompt into a new chat.
- Replace the [placeholders]. Swap any bracketed fields for your company name, audience, product or tone.
- Run and refine. Review the output. If anything is off, ask the AI to tighten tone, length or format.
Prompt Variants by Model
Act as a brand strategist. Build a voice and style guide from my content.
My best content:
<examples>
[PASTE 3-5 PIECES]
</examples>
Business [TYPE] · audience [WHO] · personality (3 words) [e.g., "sharp, warm, no-BS"] · voices I admire [1-2 brands and why] · writing I dislike [what feels wrong]
Create:
1. Voice profile — 3-4 sentences with an archetype
2. Tone spectrum on 5 scales (formal-casual, serious-playful, etc.)
3. Vocabulary rules — words we use, words we never use
4. 8 do/don't example pairs
5. Platform adaptations — website, email, social, support
6. Reusable AI voice prompt — one paragraph anyone can paste into any AI tool
7. 3-question litmus test for brand consistency
Success means the do/don't pairs are drawn from patterns in the content I pasted, and text written with the AI voice prompt would pass the litmus test.
Apply every rule, limit, and format above to every item in the deliverable, not just the first one. Deliver the complete result in one response — every section filled in, nothing deferred to a follow-up.
If a required input is missing, ask for it once before starting; otherwise proceed and label any assumption you made.Notes: R40 refresh; tuned to vendor prompting guidance
