    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 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, 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.

    PaperTrail lets you watch any Google Doc being written from the very first keystroke to the last. Open it on a student's document and you'll see exactly how the text came together — every word typed, every paragraph rewritten, every chunk of text that appeared all at once.
    
    HOW IT WORKS
    
    Click the PaperTrail bubble on any Google Doc or Classroom document. The sidebar opens and analyses the full revision history in seconds. Then hit Open Playback to watch the document rebuild itself in real time.
    
    During playback, additions are colour-coded so your eye goes straight to what matters. Small additions glow green and fade quietly — normal typing. Medium additions flash amber — a pasted sentence, worth a glance. Large additions pulse red — hundreds of characters appearing in a single revision. At 25x or 50x speed you can scan a long essay in seconds and the red flashes tell you exactly where to look.
    
    WHAT MAKES IT DIFFERENT
    
    Most revision tools tell you that something was pasted. PaperTrail shows you what was pasted — the full text, with the timestamp and author, right there in the sidebar.
    
    The paste comparison window is unique. Click Compare in the Paste Events section and every flagged paste opens side by side with a similarity score between each pair. A score above 70% means two pastes share most of the same words — a strong signal that content was moved around to look more original than it is. This catches something playback alone doesn't.
    
    The sidebar also gives you a risk score from 0 to 100, a correction ratio (human writers typically delete 15-35% of what they type — very low ratios are a flag), writing session breakdown, and a revision timeline where every paste event is marked in red.
    
    WHO IT'S FOR
    
    Teachers who want to understand how a piece of writing was actually produced. Academic integrity coordinators who need to document unusual writing patterns. Anyone who has ever looked at a polished essay from a student who struggles in class and wondered how it got written.
    
    PaperTrail doesn't make accusations. It makes the writing process visible so you can have an informed conversation.
    
    PRIVACY
    
    PaperTrail reads revision data directly from Google's own API — the same data behind the built-in revision history. Nothing is sent to any external server. No data is stored between sessions. No account required. Everything runs locally in your browser.
    
    Works in Google Docs and Google Classroom. Free, with no usage limits.
