Extract Your Brand Voice From Your Own Writing, Then Reuse It
Get a voice instruction block that makes every future output sound like you.
You are a linguist and brand voice analyst. Analyze observable patterns in my writing. Do not describe my voice with adjectives until you have evidence for each one. MY SAMPLES [PASTE WRITING SAMPLES — 3 to 5 pieces I actually wrote, not edited by anyone else] STAGE 1 — MEASURE Report, with a short quoted example for each: - Average sentence length and how much it varies - Paragraph length and rhythm (do I stack short lines, or build long ones?) - Vocabulary level and any specialist or regional words - Formality level and where it shifts - Humor: present or not, and what type (dry, self-deprecating, absurd, none) - Emotional intensity and where I raise or lower it - How I open a piece — pattern across all samples - How I close — pattern across all samples - Transitions I actually use between ideas - Punctuation habits, including dashes, ellipses, parentheses, sentence fragments - Phrases and constructions I repeat - Persuasion style: evidence, story, direct assertion, questions, contrast - Point of view and how often I address the reader directly STAGE 2 — INFER Only now, name 5 adjectives for my voice. Each must cite a specific pattern from Stage 1 as evidence. Discard any adjective you cannot evidence. STAGE 3 — DEFINE THE EDGES List what my voice never does — words, structures, tones absent from every sample. This is what stops future output sounding like generic AI. STAGE 4 — BUILD THE INSTRUCTION Write a reusable "write in this voice" block under 200 words that I can paste at the top of any future prompt. It must contain concrete rules (sentence length targets, punctuation, opener style, banned constructions), not adjectives. STAGE 5 — PROVE IT Rewrite this sentence in my voice: "We help businesses improve their marketing results." Then explain which of my patterns you applied. If my samples are too short or too inconsistent to support this analysis, say so directly and tell me what to send instead.
How to use this prompt
- Copy the whole template — the structure matters as much as the words.
- Replace every bracketed placeholder with your real details. Vague inputs produce vague output.
- Paste it into ChatGPT, Claude or Gemini and let it finish before you judge it.
- Give one round of feedback: name what to keep, what to cut, and what to change, then ask for the revised version.
Why it works
This prompt gives the model a role, the background it cannot guess, the outcome you actually want, the limits it must respect and the exact format for the answer. Those five pieces are the difference between a generic paragraph and something you can use. The words behind them are explained in the prompting glossary.
