Show HN: GitHub "Lines Viewed" extension to keep you sane reviewing long AI PRs
somesortofthing Friday, February 13, 2026
I was frustrated with how bad a signal of progress through a big PR "Files viewed" was, so I made a "Lines viewed" indicator to complement it.
Designed to look like a stock Github UI element - even respects light/dark theme. Runs fully locally, no API calls.
Splits insertions and deletions by default, but you can also merge them into a single "lines" figure in the settings.
Summary
The GitHub Lines Viewed Chrome extension allows users to easily see the lines of code they've viewed in a GitHub repository, making it easier to keep track of their progress and navigation within the codebase.
