ChatGPT Voice Prompts

Twelve copy-paste ChatGPT voice prompts that make ChatGPT or Claude write in your brand voice, not generic AI voice, from LinkedIn posts to support replies.

Twelve prompts, ready to paste into ChatGPT or Claude. Each has a slot for your Voice Charter (your 25-word "who we are, who we serve, how we sound" sentence). No charter yet? Grab the Voice Charter Template first; these prompts are only as good as what you feed them. They're the day-to-day toolkit for the Cohesion pillar.

How to use: paste prompt 1 at the start of any session, then use prompts 2 through 12 as needed inside that same session.

1. The voice-loading system prompt

Start every session with this. It does more than all the others combined.

You are a writer for a brand with this voice: [PASTE VOICE CHARTER]. Approved feelings: [3 to 5 adjectives]. Banned feelings: [3 to 5 adjectives]. Banned words: [your list]. Rules: Write like a smart person talking, not a brand performing. Every claim must be concrete (a number, an example, a named thing). No summary closers. No exclamation points unless I use one first. Vary sentence length. When unsure, choose clear over clever. Before writing anything, confirm you've loaded this voice in one sentence, then wait for my request.

2. LinkedIn post

Write a LinkedIn post in the loaded voice about [TOPIC]. Under 200 words. Open with a specific moment or number, not a hook formula. One idea only. End with a question or a plain ask, never "Thoughts?" No hashtag pile: two hashtags maximum.

3. Email newsletter section

Write a newsletter section in the loaded voice about [TOPIC], 120 to 180 words. Assume the reader knows us; skip introductions. Subject line options: give me 3, each under 45 characters, none clever at the expense of clear.

4. Blog intro

Write the first 100 words of a blog post about [TOPIC] in the loaded voice. Rules: no throat-clearing, no "in this post we'll cover," no dictionary definitions. Start where the reader's problem starts. The reader should know by sentence two whether this post is for them.

5. Support reply

Write a support reply in the loaded voice. The customer's issue: [PASTE ISSUE]. Structure: acknowledge the frustration in one line, give the fix in numbered steps, end with one sentence inviting them back if it doesn't work. Warm but efficient. No "we apologize for any inconvenience."

6. Rewrite in my voice

Rewrite the following text in the loaded voice. Keep every fact, name, and number exactly as written. Change only tone, rhythm, and word choice. Flag anything you couldn't make sound like us and tell me why. Text: [PASTE TEXT]

7. The de-AI-ify pass

Edit this draft to remove AI tells. Specifically: delete scene-setting openers ("In today's world"), delete "It's important to note," break up rule-of-three sentence stacks, remove the summarizing final paragraph, replace vague intensifiers (incredibly, truly, seamlessly) with specifics or nothing, and vary sentence length so no two consecutive sentences share a structure. Keep the meaning intact. Show me a list of what you changed. Draft: [PASTE DRAFT]

8. X / short social

Write 3 versions of a post for X in the loaded voice about [TOPIC]. Each under 250 characters. One observation, one question, one blunt statement. No thread. No "hot take" framing.

9. Sales page section

Write a sales page section in the loaded voice for [OFFER] at [PRICE]. Name what the buyer gets, item by item, and what happens after they pay, step by step. No urgency theater, no "spots are filling fast" unless it's literally true and I've told you so.

10. The voice check

Score the following text against the loaded voice, 1 to 10, on: sounds like us, concrete claims, banned words avoided, and would-a-human-say-this. For anything under 8, quote the offending line and rewrite it. Text: [PASTE TEXT]

11. Idea expansion without drift

Here are my rough notes: [PASTE NOTES]. Turn them into a full draft in the loaded voice. Do not add claims, examples, or opinions I didn't give you. Where my notes are thin, insert [NEED: description] markers instead of inventing material.

12. The channel recast

Take this finished piece and recast it for [CHANNEL]. Keep the core idea and the loaded voice. Adjust length and structure to fit the channel's norms, and tell me in one line what you changed and why. Piece: [PASTE PIECE]

Three habits that make these work

  1. One session, one voice. Load prompt 1 once, then stay in that conversation. Starting fresh chats all day means re-teaching your voice all day.
  2. Always run prompt 7 before publishing. Even good drafts pick up one or two tells.
  3. When output drifts, fix the charter, not the chat. If you correct the same thing three times, that correction belongs in prompt 1 permanently. That's the whole game: your prompts should improve weekly, because your edits feed them.
