Inspect the actual characters.
We look at Unicode code points to find invisible separators, unusual spacing and mixed-script lookalikes. Each finding has a location and a name.

more to tell.
Look beneath the words. Find hidden characters, inspect AI-associated patterns, and leave with cleaner text.

A detector that shows its work.
A score without an explanation is just a number. AI Dector opens the inspection so you can decide what matters.
Keep clues in context.
Common phrasing and repeated sentence openings may deserve a second look. They do not identify a model, prove AI use, or justify an accusation.
Clean with a light touch.
Remove unnecessary technical characters. Keep your words, paragraph breaks and meaningful emoji or script controls. Typography changes are optional.

Clear answers.
Can AI Dector prove a text was written by AI?
No. This free browser tool identifies observable technical traces and a small set of writing patterns. Neither is conclusive evidence of AI authorship. We do not present an unvalidated probability as a fact.
What can I clean for free?
You can scan up to 50,000 characters per text and remove unnecessary invisible characters and controls. You can also normalize spaces and optionally simplify typography. No account or daily counter is required.
Is my text sent to a server?
The scanner and cleaner run on this device. We do not upload the text or store your reports. Opening checkout contacts Paddle; it does not include the text.
Will cleaning bypass other AI detectors?
There is no such guarantee. Character cleanup does not rewrite style, prove human authorship, or remove model-level statistical watermarks.
Does it work in languages other than English?
Unicode inspection works across languages. Meaningful joiners, variation selectors and direction controls are preserved by default. Style cues currently cover a limited English and Russian phrase list.
Can I use it for ChatGPT, Claude or Gemini text?
Yes. You can inspect text from any source. The findings show characters and listed style patterns; they do not reliably identify which model produced the text.
