AI Prompt to Rewrite Copy in Brand Voice

AI prompt to rewrite in brand voice: paste bland copy, get on-brand text with a change log. Free template. Start getting better output in under a minute.

The prompt

You are [BRAND]'s voice guardian. You rewrite off-brand copy until it sounds unmistakably like us.

CONTEXT: Brand voice summary: [VOICE_SUMMARY]. Key voice rules: [VOICE_RULES]. Here is the copy to rewrite:
---
[COPY_TO_REWRITE]
---
Where this copy appears: [PLACEMENT, e.g. checkout email]. Audience: [TARGET_AUDIENCE].

TASK: Rewrite the copy fully in [BRAND]'s voice.

FORMAT:
1. The rewritten copy, ready to publish.
2. Change log: 5-8 bullets, each naming what changed and which voice rule it follows (e.g. "Cut 'utilize' → 'use' per Rule 3: plain words").

CONSTRAINTS:
- Keep all facts, prices, dates, and names exactly accurate.
- Match [VOICE_SUMMARY] in every sentence — read it aloud as a final check.
- Keep the same approximate length unless the voice rules demand shorter.
- If a sentence can't be made on-brand without changing its meaning, flag it instead of forcing it.
- Save every approved rewrite in a shared folder; within a few months you will own a library of on-brand examples better than any guide.

Variables to fill in

Replace each [variable] in the prompt with your own details:

[BRAND] [VOICE_SUMMARY] [VOICE_RULES] [COPY_TO_REWRITE] [PLACEMENT] [TARGET_AUDIENCE]

Example input

BRAND='Pippa Paper Co.', VOICE_SUMMARY='cheerful, crafty, like a creative friend', VOICE_RULES='short sentences; contractions always; no corporate words; one exclamation max', COPY_TO_REWRITE='We are pleased to inform you that your order has been dispatched...', PLACEMENT='shipping confirmation email', TARGET_AUDIENCE='stationery lovers'

How to use this prompt

Use this whenever freelancers, developers, or legal hand you copy that 'says the right thing wrong.' The change log doubles as voice training for whoever wrote the original.

Tips for the best results

Rewrite in batches — do all transactional emails in one session for consistency.
If the AI keeps missing the voice, your VOICE_SUMMARY needs sharpening, not the prompt.
Keep approved rewrites as examples in your voice guide.
