GPTBypass vs Undetectable.ai

Undetectable.ai is the most-recognised name in the humaniser category, with broad detector coverage and a large user base. Where GPTBypass is built differently is what carries the promise: we lead with the free detector first (see your real risk before you pay), and the paid fix passes Turnitin under a Green-Or-Free guarantee tied to an on-page re-scan — not a flattering in-app 0% score that real detectors still catch.

Your Turnitin AI score

--Awaiting scan

Run a scan to see your Turnitin AI score.

Free to check · nothing saved · no one ever finds out

Scores vary — check before you submit. Nothing saved, no account, no one finds out.

That's the whole difference. The Powerful Model rewrites the AI fingerprint so detectors read your work as human, and the Green-Or-Free guarantee carries the claim. If a shielded draft still flags on our verified re-scan, we re-humanise it free, and if it still won't pass, you're refunded in full — same day.

The student-specific touches matter too: a true per-detector breakdown instead of a single reassuring number, Citation-Keeper Mode so your references and argument survive, real free limits with no advertised-but-throttled bait, and a literal privacy promise — we never store, sell, or train on your essay. Run your draft through the free detector below and make it pass before you submit.
