Brand Voice DNA Prompt: Make AI Write Exactly Like You

How to Use the Brand Voice DNA Prompt

What This Does

This prompt analyzes your real writing samples and builds a complete Brand Voice DNA Profile — a structured, reusable document that tells any AI exactly how you write, so future outputs sound like you without constant editing.

Step 1: Gather Your Writing Samples

Find 3 to 5 pieces of writing you created without heavy editing. These could be emails you dashed off, Instagram captions, newsletter sections, DMs, LinkedIn posts, or any off-the-cuff writing. The less polished, the better — your real voice lives in unguarded writing, not in the version you rewrote three times.

Step 2: Fill In the Required Parameters

You need three things to run this prompt.

• WRITING_SAMPLES: Paste the full text of 3 to 5 real writing samples. More context gives the system more to work with.
• CREATOR_NAME: Your name or brand name as it should appear in the profile header.
• PRIMARY_CONTENT_TYPE: The main format you publish — for example, weekly newsletter, LinkedIn posts, Instagram captions, sales page copy, or YouTube scripts.

Step 3: Add Optional Parameters If Relevant

• COMPETITORS_TO_AVOID: List any brands or creators you do not want to sound like. This defines your voice’s active anti-patterns.
• DREAM_READER: One sentence describing your ideal reader. Skip it and the system will infer from your samples.

Step 4: Run the Prompt

Paste the full prompt with your filled-in parameters into ChatGPT, Claude, or Gemini. The output will include your sentence rhythm pattern, vocabulary fingerprints, emotional register description, punctuation and formatting habits, a list of what your voice never does, and a master AI instruction block ready to reuse.

Step 5: Verify With the Calibration Test

The profile includes three short sample outputs written in your voice. Read them out loud. If they sound like something you would actually say, the profile is accurate. If something feels off, identify whether it is rhythm, word choice, or tone — and add a correction note to the master instruction block before saving.

Step 6: Save and Reuse

Copy the master AI instruction block into a notes app, Notion page, or document you can access easily. Paste it at the top of any future AI prompt for any content type, and your output will start from your voice instead of a generic baseline.

Pro Tip

The more unedited your samples are, the more precise the profile will be. If the first run feels slightly off in one area, add two or three additional examples that better capture that element and run the prompt again.
