Every detector claims accuracy. We measure ours and publish the numbers — by language, by kind of writing, on a corpus you can inspect.
Free scan: we analyze your first ~300 characters
We keep your document so you can find it again, and you can delete it whenever you want. We do not sell it. Manage or delete
One detector says 60%. Another says 10%. Which do you trust? We measured them ourselves and published the numbers.
No single detector is both accurate and authoritative. OmniDetect keeps several, tests them on its own frozen corpus, and sends your text to one of them rather than to an average — then shows you the passages and the reasoning.
Try it before you decide. Guest users get a real analysis of the opening of their document — no sign-up, no card. A free account covers the whole document.
We keep what you submit so it stays in your history and so we can measure our own accuracy against real writing. You can delete any of it, any time, with or without an account. We do not sell it, and the only outside parties who see it are the detection engines that analyse it.
Results in under 5 seconds. Perfect for deadline-night essay checks, last-minute assignments, or bulk content verification.
We don't guess — we verify with multiple independent sources.
Paste up to 50,000 characters. Your text goes over HTTPS to the engine that reads it, and a copy stays in your history until you delete it.
Your language decides which engine answers, and the choice comes from our own benchmark rather than a vendor pitch. The verdict and the passages behind it arrive together.
Results are aggregated into an OmniScore (0-100). When engines agree, confidence is high. Our AI Writing Coach explains flagged patterns and suggests improvements.
We measured the major detectors on one frozen corpus — ours included. See how the numbers compare.

Pay for one scan. Get three independent opinions.
Billing is per word, for the engine that actually read your text. No subscription to a detector you never use, and no charge for engines that never saw the document.
When all engines agree, you can be confident. When they disagree, you know to investigate further. Either way, you're better informed than with any single tool.
AI Writing Coach, Edit & Rescan loop, and privacy-first architecture. OmniDetect adds actionability on top of detection.
