PaperTrail

Academic integrity tools for Google Docs. Revision history, authorship consistency, and AI analysis — no verdicts, just evidence.

You've read thousands of student essays. You know when something's off. PaperTrail Academic was built by a teacher who needed more than a hunch. Most writing process tools show you what happened. PaperTrail shows you what happened, helps you analyze whether the writing is consistent with the student, and gives you a structured, documentable report before you have the hardest conversation in teaching. No verdicts. No accusations. Just evidence — organized, objective, and defensible. ✏️ Inspect — Free, no account required Everything you'd expect from a revision history tool, and more. See the complete writing timeline, watch a full replay with paste and deletion moments highlighted, detect external content, track writing sessions and time on task. Every feature Revision History offers. 🔍 StyleMatch — Built by a teacher who knows what "this doesn't sound like them" actually means Client-side stylometric analysis across 8 authorship metrics: function word profile, punctuation fingerprint, sentence length and rhythm, type-token ratio, readability grade, and informality markers. Compare a controlled writing sample against submitted work. Every metric stands independently: no composite score, no overall verdict. The Authorship Consistency Report is yours to interpret. No student text ever leaves your device. 🔬 Verify — For when you want to be thorough before the conversation AI-assisted deep analysis in two modes. The Consistency Report chunks the essay and scores it across six dimensions — register, vocabulary, sentence complexity, argument depth, error density, and cohesion — rendered as a heatmap with a writer baseline profile. The Baseline Deviation Report compares submitted work against a known writing sample across ten dimensions, with AI-suggested follow-up questions and research citations. Transmitted text is not retained after analysis. Why PaperTrail? Other tools give you replay. PaperTrail gives you replay, analysis, and a report built by someone who has sat across from a student and a parent and needed something more than a gut feeling. Academic integrity isn't about catching students. It's about having a structured, repeatable, documentable conversation grounded in evidence. PaperTrail is built for that conversation. Privacy Inspect: zero data transmitted, all analysis local. StyleMatch: entirely client-side, no text ever transmitted. Verify: text transmitted for analysis only, not retained.
