Features
Full Writing Replay
Watch any Google Doc being written from scratch, keystroke by keystroke. Control playback speed (1x, 2x, 4x) and scrub through the timeline.
Paste & AI Detection
Automatically flags large text insertions that indicate copy-paste or AI-generated content. Configurable threshold for what counts as "large."
Evidence Summary (Pro)
Generate a one-click PNG evidence report showing writing timeline, paste events, and authorship statistics — perfect for teachers and editors.
Revision Statistics
See total revisions, typed characters, pasted characters, paste ratio, active writing time, and more at a glance.
Smart Timeline
Visual timeline with color-coded markers for paste events. Long pauses are compressed so you see the writing flow, not the waiting.
Minimal Permissions
Only accesses Google Docs pages. Does not read other tabs, track browsing history, or collect personal data. All analysis happens locally.
How It Works
Open any Google Doc
Navigate to a Google Docs document. WriteTrace automatically detects it and shows a floating action button.
Click "Analyze"
WriteTrace loads the full revision history from Google's servers and prepares the replay. This may take a few seconds for large documents.
Watch the replay
See the document being written in real time. Paste events and large insertions are highlighted in the timeline. View statistics and generate evidence reports.

Frequently Asked Questions
How does WriteTrace access revision history?
WriteTrace reads the revision data that Google Docs already stores for every document. This is the same data that powers Google Docs' built-in "Version history" feature, but WriteTrace presents it as a visual replay.
Can I use WriteTrace on documents I don't own?
Yes, as long as you have view access to the document. WriteTrace works with any Google Doc you can open in your browser.
Does it work with Google Workspace (enterprise)?
Yes. WriteTrace works with personal Google accounts and Google Workspace accounts, as long as the document's revision history is accessible.
What data does WriteTrace collect?
WriteTrace processes everything locally in your browser. Document content and revision data never leave your device. The only network request is license key verification for Pro users.
How is this different from Draftback?
Draftback was a pioneering tool but is no longer actively maintained. WriteTrace offers paste/AI detection, evidence summary export, a modern UI, and active development — at a fraction of the cost.
