Know what’s actually AI-written, before the score does the deciding.
We test AI detectors and humanizers head-to-head, false positive rates, bypass resistance, LMS fit, so teachers, students, and writers can trust a score before it changes someone’s outcome.
Top AI detector tools, tested
Ranked on false-positive rate first, because a wrongly flagged student or writer is the real cost of getting this wrong.
Pangram Labs
A verified near-zero (0.01%) false-positive rate, with hybrid and AI-assisted writing detection across 20+ languages.
GPTZero
Trusted by over 3,500 colleges, with a sentence-level deep scan mode and a free tier of 10,000 words per month.
Turnitin
The default academic integrity tool inside most LMS platforms, scanning for AI writing, paraphrasing, and source plagiarism together.
AI humanizers & bypass tools, stress-tested
We run every humanizer back through the detectors above to see what actually survives, not just what the vendor claims.
Undetectable AI
The leading AI rewriter designed to bypass major detectors by restructuring syntax, adjusting perplexity, and introducing natural human burstiness.
StealthWriter
Its Ghost Mode aggressively transforms AI drafts, producing multiple alternative humanized versions per pass.
editGPT
Keeps a natural editorial tone while removing the robotic patterns that trip academic scanners, with visible track changes.
Built for whoever’s holding the score
The right question about an AI score depends entirely on which side of it you’re standing on.
For teachers
False positive rates, ESL bias, and how to act on a flagged essay without a false accusation.
