Visor — Who Wrote What: Google Docs History

See who wrote what on any Google Doc or Google Slide — who typed what, who pasted what, and what was deleted along the way. Built for group projects, collaborative drafts, and any document where the final version doesn't tell you much about how it got there. Free and unlimited: every feature on every document, no monthly cap, no account, no sign-in. Open a doc you can edit, click Visor, and it rebuilds the editing history from the document's own edit log. Who wrote what: Every surviving character is traced back to the edit that put it there, so contribution is counted rather than estimated. On a group project, that's the difference between knowing who did the work and guessing. Watch it get written: Replay the document character by character, at the pace it was actually typed. Scrub to any moment, change the speed, or jump straight to a paste. Pastes detection and categorization: Text pasted in from outside is separated from text moved around inside the document. Rearranging your own paragraphs isn't the same thing as importing a block, and it shouldn't look the same. The threshold is worked out per document, because Google bundles fast typing into larger edits and one person's typing is another person's paste. Recover deleted text: Anything written and then removed is still in the edit log, along with who removed it and when. It doesn't survive anywhere else — not in the document, not in an export. Sessions and activity: Edits are grouped into working sessions: days worked, busiest day, longest stretch, and the gaps in between.
