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 does a writing checker do in 2026?
Beyond grammar and plagiarism, modern writing checks include AI detection. OmniDetect uses the engine measured most accurate for your language to verify your writing hasn't been flagged as AI-generated — a critical check for academic and professional content.
Can a writing checker tell if I used AI?
AI detectors analyze writing patterns like perplexity and burstiness. OmniDetect shows which passages drove the verdict and publishes its own false-positive rate for that kind of writing — with both, you can judge the result is reliable.
How do I improve my writing to avoid AI flags?
OmniDetect's AI Advisor highlights exactly which sentences were flagged and explains why. Common triggers: overly uniform sentence length, generic phrasing, and lack of personal voice. Edit those sections in your own words, then rescan.
Is this a grammar checker too?
OmniDetect focuses specifically on AI content detection, and publishes its own false-positive rate by language and kind of writing. For grammar checking, pair us with Grammarly or ProWritingAid. For plagiarism, use Turnitin or Quetext alongside OmniDetect.
Can I check my writing for free?
Yes. 3 free scans per day with analysis by a real commercial engine on the first ~300 characters. No sign-up needed. Register for 1,000 free Word Tokens to unlock all the measured engine on the full text.
