Passed.AI

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 — Watch exactly how a student wrote their document at adjustable playback speed; see every keystroke, deletion, paste, and revision in chronological sequence; the only tool in the reviewed academic integrity market that provides full writing visualization rather than a static score.

• Document Audit — Comprehensive per-document report including AI Reliance Score, Plagiarism Score, Paste-In Analysis (all pasted content with timing and source), Revision Tracking (detailed change history with timestamps), Flow Score (natural writing progression vs. AI insertion patterns), Contribution Analysis (individual inputs in collaborative documents), and Time Investment Assessment (duration spent on the document).

• AI Detection (Powered by Originality.ai) — Originality.ai is partnered directly into the Passed.AI platform for best-in-class AI detection accuracy; trained on ChatGPT, GPT-2, GPT-3, GPT-J, and GPT-4 outputs; returns sentence-level Human vs. AI probability scores; English only.

• Plagiarism Check (Powered by Originality.ai) — Identifies non-cited passages against external online sources; returns specific source matches; integrated into the same Document Audit report as AI detection for a unified submission review.

• Chrome Extension (Google Docs Integration) — Integrates Passed.AI's full Document Audit directly into Google Docs; enables in-app analysis without exporting documents to an external dashboard; the primary workflow path for educators using Google Workspace.

• Academic Honesty Reports — Students wrongly accused of AI use can submit their documents to Passed.AI for a formal, evidence-backed report using the same Document Audit and Replay Tool that educators use — providing a documented defense mechanism accessible directly through the platform.

• Credits System (Pay-As-You-Go) — Each subscription includes 200 credits per month that roll over and never expire; each credit covers up to 200 words at one cent per credit; credits unlock advanced AI detection and plagiarism scan features beyond the base unlimited scans included in the subscription.

• Flow Score — Measures the natural progression and coherence of writing within a document to distinguish organic human drafting patterns from AI-generated content blocks inserted in unnatural uniformity — a secondary check layer that reduces false positives from stylistically consistent human writers.

Passed.AI is purpose-built for educators, academic institutions, and students navigating academic integrity disputes — not for content marketers, SEO professionals, or general AI writing workflows.

• Teachers and university professors — use the Document Audit and Replay Tool to evaluate submitted assignments with full writing process visibility; the secondary checks (Paste-In Analysis, Flow Score, Revision Tracking) provide defensible, context-rich evidence for academic misconduct conversations rather than a single contestable percentage score.

• Academic institutions and departments — the $9.99/month flat-rate unlimited scan pricing makes Passed.AI accessible for individual educators without institutional procurement; the Chrome Extension integrates into existing Google Workspace environments with no IT infrastructure change.

• K-12 schools using Google Classroom — the Chrome Extension's Google Docs integration is optimized for the Google Workspace for Education environment dominant in K-12, making Passed.AI the most frictionless AI integrity tool for this specific technology stack.

• Students wrongly accused of AI use — Academic Honesty Reports provide formal, evidence-backed documentation of genuine human authorship using the same tools educators use, giving students an accessible professional-grade response to false positive accusations.

• Academic integrity officers and department heads — the Contribution Analysis feature for collaborative documents, combined with timestamped Revision Tracking and the Replay Tool, provides the level of documented, timestamped evidence required for formal academic misconduct proceedings.

Passed.AI's differentiators are the Replay Tool, the Document Audit's multi-layer secondary checks, the Academic Honesty Report for students, and the Originality.ai partnership — creating the only academic integrity platform that addresses both institutional detection and student defense in one subscription.

• Replay Tool (Writing Process Visualization) — No other reviewed academic integrity or AI detection tool allows educators to literally watch a document being written. The Replay Tool plays back every keystroke, paste event, deletion, and revision at adjustable speed — transforming the adjudication conversation from ‘your AI score was 87%' to ‘here is the documented evidence of exactly how this document was created.' This shifts the burden of proof from contested percentages to observable behavior, which is fundamentally more defensible in a formal academic misconduct process.

• Document Audit Multi-Layer Secondary Checks — The combination of AI Reliance Score, Plagiarism Score, Paste-In Analysis, Flow Score, Revision Tracking, Contribution Analysis, and Time Investment Assessment in a single report is unique in the market. Single-metric tools (GPTZero, Copyleaks, Winston AI) return one number; Passed.AI returns a contextualized behavioral profile of how the document was created — dramatically reducing false positive risk.

• Academic Honesty Report (Student Defense Tool) — Passed.AI is the only reviewed academic integrity platform that builds an explicit student-side service: providing formal, evidence-backed reports for students facing wrongful AI accusations. This dual institutional/student positioning is unique in the category and directly addresses the AI detection fairness concern raised by academic researchers and covered in major press including NPR and NBC News.

• Originality.ai Partnership (Detection Accuracy) — Rather than maintaining a proprietary detection engine (which requires continuous retraining as LLMs evolve), Passed.AI partners with Originality.ai — the provider independently rated as the highest-accuracy AI detector in the market. This partnership gives Passed.AI access to state-of-the-art detection accuracy without the engineering overhead of maintaining a competing detection model.

Passed.AI is a web app with a Chrome Extension — optimized for Google Workspace for Education environments and accessible on any modern browser through the dashboard.

• Web App (passed.ai) — Fully browser-based dashboard accessible on any modern desktop browser (Chrome, Firefox, Safari, Edge); paste-and-scan interface for AI detection, plagiarism checking, and Document Audit without Google Docs; suitable for non-Google Workspace institutions.

• Google Chrome Extension (Google Docs Integration) — The primary integration path for K-12 and higher education Google Workspace environments; integrates the full Document Audit (AI Detection, Plagiarism Check, Paste-In Analysis, Revision Tracking, Flow Score, Replay Tool) directly into the Google Docs interface; monitors document writing in real-time without requiring manual exports.

• Google Docs (Full Native Integration) — The platform is specifically designed around Google Docs as the primary document environment; Document Audit features including Contribution Analysis, Time Investment Assessment, and Replay Tool leverage Google Docs' native version history and collaboration metadata for maximum data richness.

• Originality.ai (Detection Engine Partnership) — AI Detection and Plagiarism Checking are powered by Originality.ai's proprietary engine, trained on ChatGPT, GPT-2, GPT-3, GPT-J, and GPT-4 outputs; English language only; returns sentence-level probability scores embedded within the Passed.AI Document Audit report.

• All Languages (Document Audit and Replay Tool) — The Document Audit, Replay Tool, History Report, Paste-In Analysis, Revision Tracking, Flow Score, and Contribution Analysis features work regardless of document language; only AI detection and plagiarism checking are limited to English content due to the Originality.ai engine's training scope.

Passed.AI is the most contextually complete academic integrity platform in the reviewed market — the only tool that shows educators exactly how a document was written, not just whether AI was suspected. The Replay Tool, Document Audit multi-layer secondary checks, Originality.ai partnership, Chrome Extension for Google Docs, and Academic Honesty Reports for students create a feature set no direct competitor replicates at $9.99/month for unlimited scans. English-only AI detection, no API, Google account dependency, limited payment methods, and no live chat are real limitations.

For educators in Google Workspace environments who need defensible, process-documented evidence for academic integrity decisions — not just a detection percentage — Passed.AI is the most capable and most affordable purpose-built solution available.
