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
GPTZero, Winston AI, and Originality.ai each analyze your text independently.
Consensus-Based Scoring
When all three engines agree, you can trust the result.
Privacy First
Your text is never stored. Only a SHA-256 hash for caching. GDPR compliant.
Frequently Asked Questions
Can OmniDetect check for plagiarism?
OmniDetect focuses on AI content detection using 3 independent engines. For plagiarism checking, we recommend pairing OmniDetect with dedicated tools like Turnitin, Grammarly, or Quetext for complete coverage.
Why do I need both plagiarism AND AI detection?
Plagiarism checkers find copied text. AI detectors find machine-generated text. A student could submit 100% original text that was entirely written by ChatGPT — a plagiarism checker would miss it completely.
Is the AI detection free?
Yes. OmniDetect offers 3 free scans per day with real GPTZero analysis on the first ~300 characters. No credit card needed. Sign up for 1,000 free Word Tokens to unlock all three engines.
What is the best free plagiarism and AI checker combo?
Use a dedicated plagiarism tool (Turnitin for institutions, Quetext or Grammarly for individuals) alongside OmniDetect for AI detection. This gives you both copied-text and AI-generated-text coverage in one workflow.
Can AI-generated text pass plagiarism checkers?
Yes. AI generates original text that won't match any existing source. Plagiarism checkers give it a clean bill — but AI detectors like OmniDetect catch the machine-writing patterns.
