Sound Like You: Free ChatGPT Prompt and Custom Instructions

Two free downloads in one PDF: a copy-and-paste prompt that interviews you first and writes from your story, plus short custom instructions you set once so every chat writes in plain words. Works in ChatGPT and Claude.

Two downloads in one PDF

1. Sound Like You: the prompt (pages 1 and 2)

Use it for one post or one email. Paste it into a new chat and ChatGPT interviews you before it writes anything:

Then it writes from your answers, in plain words, without inventing facts. It avoids the habits that make writing sound like AI, runs a "delete test" on every line, and shows you only the draft. There's also an edit mode for polishing your own writing without changing what you mean.

2. Sound Like You, Always On: custom instructions (page 3)

Set it once and every new chat follows it. It fits in ChatGPT's 1,500-character Custom Instructions box, and it works in Claude's settings or in a Claude Project. The page shows exactly where to paste it and gives three tips for keeping it working in long chats.

Who it's for

Small-business owners and anyone who uses ChatGPT or Claude to write posts, emails or updates and wants them to sound like a person wrote them.

An honest note

This won't make writing "undetectable," and I wouldn't trust any prompt that says it will. It gets ChatGPT to write from your story, in plain words, so it sounds like you.

3 pages. Free. We email it to you as a PDF.

Frequently asked questions

Is Sound Like You free?

Yes. Enter your name and email on this page and we email you one 3-page PDF with both downloads: the interview prompt and the Always On custom instructions.

Does it work in Claude as well as ChatGPT?

Yes. The prompt works in ChatGPT and Claude, and the custom instructions can go in Claude settings or a Claude Project.

Where do the custom instructions go in ChatGPT?

In ChatGPT, open Settings, then Personalization, then Custom Instructions, and make sure customization is turned on. The instructions fit in the 1,500-character box.

Will it make my writing undetectable by AI detectors?

No, and no prompt should promise that. It gets ChatGPT to write from your own story and details, in plain words, so the writing sounds like you.

What is the delete test?

Go through a draft line by line. If deleting a phrase loses no fact, number, step or part of the story, delete it. The prompt has ChatGPT run this check before it shows you the draft.
