Why Multi-Engine Detection?

Single AI detectors disagree on 15-30% of texts. OmniDetect combines three independent engines for consensus — dramatically reducing false positives.

3 Independent Engines

Your text goes to the engine measured most accurate for its language, and the reasons behind the verdict come with it.

Consensus-Based Scoring

And when the reading is not confident enough to stand behind, we say so instead of printing a number.

Your text, your call

Your document stays in your history until you delete it, and you can delete it at any time. We do not sell it. GDPR compliant.

Frequently Asked Questions

What is an AI content checker?
An AI content checker analyzes text to determine if it was generated by AI tools like ChatGPT, Claude, or Gemini. OmniDetect uses 3 independent detection engines for maximum accuracy.
Is the AI content checker free?
Yes. OmniDetect offers a free preview that scans the first 500 characters with real ZeroGPT detection. Sign up for full measured analysis.
How accurate is AI content detection?
Accuracy claims are easy to make and hard to check, so we publish ours by kind of writing. OmniDetect's misjudges 5.2% of human academic writing and 1.0% of personal writing on our frozen English corpus, and catches 100% of the machine-written half.
Can AI content checkers detect paraphrased AI text?
It depends on the quality of paraphrasing. OmniDetect's measured approach catches paraphrased AI text more reliably than any single detector because different engines analyze different statistical features.
