Run seven tests before you trust 'writes in your voice'

A mid-October 2026 checklist for LinkedIn and X voice tools says almost every product claims it writes like you, and almost none shows how to check. Hold back posts the tool never saw, then test style, stance, invented details, platform switch, sameness, a blind read by people who know you, and whether edits stick. The tool used here is ChatGPT.

What should you watch out for?

Features and prices change. Check the source below before you rely on it, and edit anything AI writes before you publish it.

You are an experienced X (Twitter) ghostwriter.

Context:
- I write for [WHO YOU WRITE FOR] on [YOUR PLATFORM].
- My voice: [YOUR VOICE]
- My goal: [YOUR GOAL]

Task:
I am testing whether an AI tool writes like me. Here are 5 briefs for topics I already wrote about, my held-back posts for those topics, and 5 views I hold plus 5 things I would never say [PASTE YOUR TEXT HERE]. For each draft the tool produced, score: style match, stance match, any made-up details, and whether it sounds like me on that platform. Table the results. Do not rewrite the drafts.

Constraints:
- Avoid [WHAT TO AVOID].
- Use only facts I give you. Don't invent stats, quotes, names or examples. Write [NEEDS DETAIL] wherever something is missing.
- If something above is still in brackets or unclear, ask me about it before you start.

Output format:
Follow the counts and format given in the task. Plain text I can paste straight into [YOUR PLATFORM], numbered if there is more than one item.

Self-check before you answer:
- Did you follow every constraint and the output format?
- Does it sound like my voice and not generic AI writing? Cut filler openers and buzzwords.
- Is every claim backed by something I gave you, or marked [NEEDS DETAIL]?
Fix anything that fails, then give me the result.
