AI Detector — Don't Guess. Know.
The Multi-Engine AI Content Detector
Tired of copy-pasting into GPTZero, then Winston, then ZeroGPT? One scan. Three engines. One answer you can trust.
Free scan: GPTZero analyzes your first ~300 characters
Your text is never stored. Only a SHA-256 hash for caching.
Why OmniDetect Beats Single-Engine Tools
GPTZero says 60%. Winston says 10%. Which do you trust? We built a better way.
The Consensus Engine
Why copy-paste into 4 different tabs? We run GPTZero, Winston AI, and ZeroGPT simultaneously — three independent verdicts, one consensus answer.
Free Before You Pay
Try the real thing first. Guest users get a genuine GPTZero analysis — no sign-up, no credit card. You only pay when full three-engine consensus is needed.
No-Log Privacy Guarantee
Your work stays yours. We never store your original essays or articles. Data is processed in RAM and cryptographically hashed.
Lightning-Fast Analysis
Results in under 5 seconds. Perfect for deadline-night essay checks, last-minute assignments, or bulk content verification.
Three Steps to Certainty
We don't guess — we verify with multiple independent sources.
Paste Your Text
Paste up to 50,000 characters. Your text is sent directly to detection engines via HTTPS and never stored in our database.
3 Engines Analyze Independently
GPTZero, Winston AI, and ZeroGPT each use different AI detection models to analyze your text simultaneously — independent verdicts, no bias.
Get Your Consensus Report
Results are aggregated into an OmniScore (0-100). When engines agree, confidence is high. Our AI Writing Coach explains flagged patterns and suggests improvements.
Why Pay for Two When You Can Have All Three?

The Arbitrage Advantage
Pay for one scan. Get three independent opinions.
Three Engines, One Price
GPTZero alone costs $10/month. Winston AI costs $14/month. Together that's $24+/month. OmniDetect gives you all three engines for $9.99/7 days.
Consensus > Single Opinion
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.
Plus Features None of Them Have
AI Writing Coach, Edit & Rescan loop, and privacy-first architecture. OmniDetect adds actionability on top of detection.
