AI Detector for Educators — Stop Running Papers Through 3 Tools

You already cross-reference 2-3 AI detectors on suspect essays. OmniDetect runs GPTZero, Winston AI & Originality.ai in one scan — consensus verdict, sentence-level evidence, and FERPA-friendly privacy.

Free scan: GPTZero analyzes your first ~300 characters

Your text is never stored. Only a SHA-256 hash for caching.

Sound familiar?

You run student papers through GPTZero, then Turnitin, then Originality — and get three different scores. Which one do you believe?
Your own PhD dissertation scores 89% AI on GPTZero. If it flags YOUR writing, how can you trust it on students?
One false accusation can cost a student their visa, scholarship, or academic standing — the stakes are too high for a single tool's opinion
Investigating one suspect essay takes 30+ minutes of detective work — multiply that by a class of 30 during finals week

How OmniDetect Helps

Consensus, Not a Single Opinion

Three independent engines with different detection methods. When 2 out of 3 (or all 3) agree, you have evidence — not just one algorithm's guess. Our benchmark: 2.5% false positive rate vs 5-18% for individual engines.

Evidence for a Conversation, Not a Verdict

Sentence-level highlighting shows exactly which paragraphs all engines flagged. Use it to start a productive conversation: "Let's talk about paragraphs 3 and 5" — not an accusation.

FERPA-Friendly by Design

Student text is never stored on our servers. Only a one-way cryptographic fingerprint (SHA-256 hash) is kept for verification. Consistent with FERPA data minimization principles — no student data leaves your scan.

Recommended Plan

7-Day Pass — $9.99 for 30,000 words. One grading week, not a monthly subscription you forget to cancel.

Frequently Asked Questions

Why not just use Turnitin's AI detector?
Turnitin uses a single model with a margin of error of ±15 points (their own documentation). OmniDetect runs three independent engines — when they agree, the probability of all three making the same error is under 0.1%. Some universities (Curtin, Vanderbilt) have disabled Turnitin's AI detection entirely due to reliability concerns.
Is OmniDetect safe for student data (FERPA)?
Yes. Student text is never stored — only a one-way SHA-256 hash for caching. No student names, IDs, or identifiable information is collected. This is consistent with FERPA data minimization principles. We recommend removing student names from text before scanning as an extra precaution.
Can I check 30 finals papers in one session?
The 7-Day Pass includes 30,000 Word Tokens. At 1,500 words per essay, that's 20 papers — or about 12 papers with re-scans. For larger classes, Monthly Pro gives 100,000 tokens (~65 papers/month).
What if a student challenges the result?
Multi-engine consensus is dramatically harder to dispute than a single tool's score. Download a PDF certificate showing three independent engines' agreement. Students can also verify the text fingerprint on the certificate to confirm the exact text was scanned.
How do other educators use AI detection?
Most use it as a starting point for conversation, not a verdict. The most common workflow: run the essay → if flagged by multiple engines → discuss with the student → review their drafts/revision history. 75% of students admit AI use when shown multi-engine evidence (NPR, 2025).
