Find the AI-writing tells in a draft, with their positions, and get a cleaned copy back.

TellsFreeFor writers and developers

Better than by hand

Finds invisible characters and counts patterns across the whole text, which a read-through by eye does not. We do not put a time on it.

Before: what you give it

The example input, as typed in. You paste text or a file's contents.

Our platform doesn't just store your data, it empowers teams to seamlessly collaborate, iterate, and ship. It's not about features. It's about outcomes.

After: what comes back

The first lines of a real run of the tool's own code on that input. Nothing here is edited by hand.

What you get

A 0 to 100 score, each tell with its excerpt and the rule behind it, and a cleaned version of the text

What it cannot do

Rule-based pattern checks, not a detector model: a clean score does not prove a person wrote it. Free tier reads 3,000 characters.

Who it is for

Writers
Developers

The form starts with the same example input, so you can run it first and then swap in your own.
