OmniType is a VS Code extension that tracks code provenance at the line level. Every line gets tagged as manually typed, AI-completed, or pasted. For individuals it answers "how much of my code is actually mine." For teams it makes AI usage visible during code review without guessing. Built on editor events rather than file watchers, with LCS diffing on large AI rewrites so preserved lines don't get wrongly attributed. Extension is free. Cloud sync and team features are paid.

Hey PH! Rishav here, maker of OmniType. This started because I genuinely had no idea how much of my own codebase I wrote versus accepted from Copilot. Same problem for my teammates. During code review there was no way to tell which lines came from AI and which were hand written. The interesting technical challenge was that file system watchers are useless for this since they fire for git pulls, formatters, everything. Attribution has to happen at the editor event level. Large AI rewrites also need LCS diffing on line hashes otherwise lines Copilot preserved get wrongly tagged as AI generated. Extension is free to install. Cloud sync and team features are paid. Happy to answer anything about how it works under the hood or where I'm taking it next.

I thought I knew my own ratio. I was wrong by a lot.

The way we write code has quietly shifted. A couple years ago almost every line was hand written. Now a chunk of it is reviewing and accepting suggestions. But nobody really knows their own number because nothing actually tracks it at the line level.
