WritingTrace is a Chrome extension that records and plays back the entire writing process in Google Docs, giving educators forensic-grade evidence of student authorship. Instead of relying on AI detectors that produce false positives up to 26% of the time, WritingTrace shows the actual keystroke timeline — every edit, pause, paste, and revision — so you can verify work through transparent process tracking.

AI detectors guess whether text was machine-generated and frequently produce false positives. WritingTrace takes a fundamentally different approach: it captures the writing process itself, providing direct evidence of how a document was actually created.
Rewind and watch the evolution of a document character-by-character. Analyze pacing, pauses, and revisions with a full keystroke timeline that captures edit velocity and writing behavior patterns.
All document processing happens on-device within the browser — no student writing data is ever transmitted to or stored on external servers. Designed from the ground up for FERPA compliance.
Seamlessly integrates with Google Docs as a Chrome extension. No new platforms to learn, no setup for students, no workflows to change — just install and open any Doc to start tracing.
Key takeaway: WritingTrace replaces algorithmic guesswork with observable evidence, shifting authorship verification from accusation to transparent conversation.

WritingTrace works by reading the fine-grained revision data that Google Docs already stores for its real-time collaboration features. It reconstructs the full editing timeline on-device — no recording, no surveillance, just the data Google already has, presented in a useful format.
Add WritingTrace to Chrome in one click. No account required to start — the extension activates automatically in Google Docs.
The WritingTrace sidebar appears with a live activity timeline. The "Trace-Cursor" maps the flow of thought, highlighting areas of high-velocity paste vs. thoughtful drafting in real time.
Play back the document's creation as a video, export an animated GIF of the edit process, or generate a forensic report with per-session analytics — all processed on-device.
WritingTrace changed the dynamic from 'Accuser vs. Student' to a supportive coaching session about the writing process. It's the forensic proof we desperately needed.

Students now feel safe to explore ideas. They know that as long as they put in the work, the evidence of their effort is automatically captured and protected.

Everything educators need to know about forensic writing playback, privacy, pricing, and how WritingTrace compares to AI detectors and alternatives.
WritingTrace is a Chrome extension that records and plays back the complete writing process in Google Docs. It captures keystroke timing, revision patterns, and edit velocity to create a forensic timeline of authorship — all processed on-device without sending student data to external servers.
No. Unlike probabilistic AI detectors that produce false positives up to 26% of the time (Stanford, 2023), WritingTrace provides direct process evidence. Instead of guessing whether text was AI-generated, it shows the actual writing timeline — edits, pauses, pastes, and revisions — so educators can make informed judgments.
Yes. WritingTrace processes all document data on-device within the browser. No student writing, revision history, or personally identifiable information is transmitted to or stored on external servers. This architecture ensures full FERPA compliance by design.
While both tools replay Google Docs revision history, WritingTrace offers forensic-grade analytics including edit-velocity mapping, paste detection with character counts, and exportable forensic reports. WritingTrace also provides on-device processing with no data sent to external servers, and a free tier of 100 documents.
Revision History focuses on AI usage flags and writing pattern alerts. WritingTrace takes a different approach: it provides raw process evidence without algorithmic judgment. Educators see the full timeline and make their own assessments. WritingTrace also includes GIF export of the edit process and detailed per-session analytics.
Yes. WritingTrace works with any Google Doc, including documents created or assigned through Google Classroom. Install the Chrome extension, open any Doc, and the WritingTrace sidebar appears with full playback and analytics capabilities.
WritingTrace collects no document content on its servers. All writing analysis happens locally in your browser. The only data stored remotely is your account email (for subscription management) and an anonymous document count for free-tier usage tracking.
WritingTrace offers a free tier that includes analysis of up to 100 documents. Premium is $9.99/month and provides unlimited document analysis, priority support, and advanced analytics features. School and district licensing with volume discounts is also available.
WritingTrace does not monitor in real-time. It reads the existing revision history that Google Docs already stores for its collaboration features. The extension is visible only to the user who installs it — students see no indication unless the educator chooses to share.
WritingTrace is available as a Chrome extension and works on any platform that supports Chrome, including Windows, macOS, ChromeOS, and Linux. It integrates directly with Google Docs through the browser.
