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.
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.
