Check a student essay for AI-generated writing in under two seconds. You get a sentence-by-sentence breakdown of which parts look AI-written, a confidence score calibrated to mean what it says, and a published account of where the checker is weak. Free to use, no account required.
Most AI checkers give you a number and no way to argue with it. This one shows its work, and tells you where it falls short.
Every result is one of four verdicts, and 'uncertain' is one of them. When the signal is weak, the checker says so instead of guessing a number that sounds authoritative.
Students rarely use AI for a whole essay. Each sentence gets scored on its own, so you can see the three AI-written paragraphs in an otherwise original piece.
Plagiarism tools match text against sources that already exist. AI writing is original by that standard, which is why it passes them. Run both; they catch different things.
Heavily rewritten AI is the case we handle worst, and the checker is English-only. Both are written up on our technology page rather than buried, so you know when to trust it.
Reviewing a whole class at once is available as a custom integration. We build it around the tools your school already uses, so submissions reach you without extra steps.
A flagged student can see exactly which sentences were flagged and how confident the checker was on each. That is a conversation you can have, not a verdict handed down.
A straightforward workflow designed to fit into your existing grading process.
Paste text directly into the analyzer or use the API to integrate with your learning management system. Works with essays, reports, and short-form assignments.
Our ensemble of detection models analyzes the text at the sentence level. Each sentence receives an individual assessment, giving you a granular view of the submission.
See an overall verdict alongside a sentence-by-sentence breakdown. Understand which parts of the text triggered detection and why.
Use the results as a starting point for discussion with students. AI detection should inform, not replace, your professional judgment as an educator.
What we measured, how we measured it, and what it cost you to find out.
Measured in our own testing across thousands of human and AI-written texts. Not a third-party figure.
Typical time to a full result, including the sentence-by-sentence breakdown.
Likely AI, possibly AI, uncertain, or likely human. The middle two exist so the checker can admit doubt.
No account, no card, no trial period. Paste an essay and read the result.
A checker catches AI writing after the fact. These are the things that reduce how often you need it.
Use detection results during drafting stages to teach students about AI-assisted writing and help them develop their own voice.
Design assignments that are harder to complete with AI alone, such as reflective writing, personal narratives, and in-class compositions.
Establish consistent detection practices across your department. We can build a custom integration for department-wide rollout so everyone works from the same setup.
AI detection for higher education admissions and research integrity.
Protect editorial integrity and verify content originality at scale.
What the AI writing percentage measures, and what Turnitin publishes about its own error rate.
Paste an essay and read the result in under two seconds: a verdict, a confidence score, and the specific sentences that triggered it. Nothing to install and no account to create.
