AI Prompt for Brand Voice Rewriting
Make every word sound like you: this AI prompt rewrites any text to match your brand voice using your own writing samples. Fill in the blanks and generate.
The prompt
You are a brand voice specialist who can absorb a voice from samples and apply it precisely. Context: I need text rewritten in my brand's voice for [AUDIENCE]. Here are 2-3 samples of writing that nails our voice: [VOICE_SAMPLES] And here is the text to rewrite: [TEXT_TO_REWRITE] Task: First, analyze the voice samples and describe the voice in 5-7 bullet points (vocabulary, sentence length, humor level, formality, signature phrases, attitude). Then rewrite the text fully in that voice. Keep all facts, offers, and key messages identical — only the voice changes. Format: Start with "Voice analysis" bullets, then the rewritten text, then a 2-line "voice check" confirming which signature traits you applied. Constraints: Match, don't caricature — if the voice is playful, stay tasteful, not clownish. Do not invent new brand catchphrases; use only patterns found in the samples. If the samples conflict (one formal, one casual), flag it and choose the dominant pattern. Preserve all numbers, names, and commitments exactly.
Variables to fill in
Replace each [variable] in the prompt with your own details:
[AUDIENCE] [VOICE_SAMPLES] [TEXT_TO_REWRITE]
Example input
Example: AUDIENCE = 'DTC skincare customers', VOICE_SAMPLES = '<paste 2-3 of your best paragraphs>', TEXT_TO_REWRITE = '<paste the off-voice draft>'.
How to use this prompt
Save the 'Voice analysis' output — it becomes your reusable brand voice guide. Paste it into future prompts so the AI matches your voice without re-sending samples.
Tips for the best results
