AI Essay Checker — Verify Your Essay Before Submission

Universities worldwide now scan every submission through AI detectors. Getting flagged doesn't just mean a bad grade — it can trigger a formal academic integrity investigation.

OmniDetect lets you check your own essay before your professor does. Paste your text, get sentence-level highlighting of flagged passages, and use the AI Writing Coach to understand why specific sentences look AI-generated. Edit, rescan, and repeat until your essay reads as authentically yours.

The key advantage: we tell you where we are unreliable. Formal academic prose is the hard case for every detector, so we publish our false-positive rate for it separately — 5.2% on our frozen English corpus, against 1.0% for personal writing. A flagged sentence in an essay deserves more scepticism than a flagged one in a blog post, and you should know that before you rewrite anything.

Academic papers are especially prone to false positives because formal, structured writing shares patterns with AI output. Our benchmark found that all 3 of our false positives (out of 118 human samples) were academic or professional texts.

For research papers, the measured approach is critical: engines disagree most precisely where formal academic prose lives. Running the engine measured most accurate for your language together means one engine's blind spot cannot become your verdict on its own — the consensus algorithm surfaces the disagreement instead of hiding it.

Paste your abstract, introduction, or full paper (up to 50,000 characters) for a thorough check. The AI Writing Coach will flag specific academic writing patterns that trigger detectors and suggest alternatives.
