Papertrail

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 considerably more. See the complete writing timeline, watch a full replay with paste and struggle moments highlighted, detect external content with novelty scoring, surface struggle moments where the writer cycled through deletions and rewrites, and track writing sessions and time on task. Every feature Google's Revision History offers — plus the 📊 Process View report, a printable, observational PDF you can save or hand to a department head. Sessions, paste activity (with the actual pasted text), struggle moments, five research-cited writing-process metrics. Fillable form fields for student and assignment, all in your browser.

No verdict, no AI, no transmission. Free.

🔍 StyleMatch — Built by a teacher who knows what "this doesn't sound like them" actually means

Client-side stylometric analysis across 7 authorship metrics: grammatical function words, discourse marker profile, discourse-marker position, punctuation fingerprint, average sentence length, sentence rhythm, and sentence-length profile. 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 seven dimensions — register, vocabulary, sentence complexity, argument depth, authorial voice, 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, three independent signals you can bring to the conversation, and a printable 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.
