Passed.AI
The only academic integrity tool that shows you exactly how a document was written — Passed.AI's Replay Tool, Document Audit, Flow Score, and Originality.ai-powered detection give educators complete writing process visibility for $9.99/month with unlimited scans.
Passed.AI is an educator-focused academic integrity platform co-founded in 2022 by Andrew Rains through Fractional SAAS Inc. (Canada). It provides AI Detection and Plagiarism Checking powered by Originality.ai, a writing process Replay Tool, Document Audit with Paste-In Analysis, Revision Tracking, Flow Score, Contribution Analysis, Time Investment Assessment, and a Chrome Extension for Google Docs.
It also offers Academic Honesty Reports for students wrongly accused of AI use. Pricing is $9.99/month for unlimited scans with 200 included credits, plus a 14-day free trial. AI detection is English-only; the Document Audit and Replay Tool work in all languages.
- ✔ Replay Tool is unique in the academic integrity market — watch the full document writing process at adjustable speed; no other reviewed tool provides live writing visualization at any price point
- ✔ Originality.ai partnership delivers best-in-class AI and plagiarism detection accuracy without Passed.AI needing to maintain a proprietary detection engine
- ✔ Document Audit secondary checks (Paste-In Analysis, Flow Score, Revision Tracking, Time Investment) significantly reduce false positives and false negatives versus single-score detection tools
- ✔ $9.99/month for unlimited scans is dramatically more affordable than Turnitin's institutional per-seat pricing for comparable academic integrity functionality
- ✔ Chrome Extension integrates directly with Google Docs — the dominant writing platform in K-12 and higher education — enabling real-time monitoring without document exports
- ✔ Academic Honesty Reports for students create a dual-purpose platform that serves both detection and defense — addressing the student fairness concern that most academic integrity tools ignore
- ✔ Credits roll over and never expire — unused credits accumulate across months, providing budget flexibility for irregular detection workloads
- ✔ 14-day free trial with full feature access and no credit card required
- × AI Detection and Plagiarism Checking are English-only — the Originality.ai engine is not trained on non-English languages, limiting the platform for educators in multilingual classrooms or international institutions
- × No API integration — documents must be submitted via the web dashboard or Chrome Extension; no programmatic bulk processing for institutions with high-volume automated review workflows
- × Requires Google account login — no email/password registration option, creating a dependency on Google authentication that may create friction in non-Google Workspace institutions
- × Limited payment methods — third-party reviewer confirms reduced accessibility due to narrow payment options versus credit card and PayPal standard coverage
- × No live chat support — the absence of real-time support is a gap for educators dealing with urgent academic misconduct cases requiring immediate platform assistance
- × Credits system adds billing complexity — determining credit costs per feature requires consulting the pricing documentation rather than a flat-rate all-inclusive subscription
- × Document Audit and Replay Tool require the Chrome Extension for real-time Google Docs integration — users on non-Chrome browsers or non-Google Docs platforms must use the manual paste-and-scan workflow
