UnTXT — AI Detector & Writing Checker

Check any text for AI tells before you submit. Seven explainable signals show which phrases look machine written and why.

Your writing has tells, and detectors find them. UnTXT shows you every one of them before anyone else looks, because it highlights each phrase that reads as machine written whenever you select some text and run a check from the right click menu. Unlike checkers that hand you a bare score, it marks each signal in its own colour, so the source of trouble is actually visible. The signals cover vocabulary spikes, syntax habits, hedging, templates, rhetoric and puffery, which are the patterns that reviewers hunt for when they suspect a draft. Click a highlight and see why. A short note explains the flag in plain English, and instead of leaving you there, the rewrite flow drops the phrase back into the editor so you can rework it until the wording feels like yours again. Students run coursework and applications through it, while professionals vet reports and letters. To be clear, the verdict stays qualitative rather than numeric, so you learn what sounds human and what needs work. Five checks are free, and no account is needed. Anonymous analysis stays on your device, while signing in adds the enhanced signals and a saved history on the UnTXT site.
