We measure AI writing tells, including our own.
Fifteen rules, checked against 959 documents written before ChatGPT existed. One of them cleared. Paste a draft and you get every flag with the rate behind it, so you know what it is worth. Free, no signup, and your text never leaves your browser.
"In today's fast-paced digital landscape, our team is thrilled to leverage cutting-edge solutions…"
Here's what happens when you paste
No account, no upload, nothing to install. Three steps, all on your own computer.
An email, a post, a memo. It stays on your screen — the check runs in your browser, not on a server.
Each highlight is a tell — a word or habit readers recognize as AI. Hover one to see why, with the research behind it.
One click per fix. Word swaps only — the structure, meaning, and voice stay yours.
A tell is a word or writing habit that AI uses far more often than people do — so often that readers have learned to spot it. You don't need to know how AI works to fix them; you just need to know which ones you're sending.
