It overlays a small info box on YouTube videos (including embedded ones) that shows:

- Time you'll save (or add) compared to 1x speed - Adjusted time remaining based on current speed - Percentage watched - Works on Shorts too

It also comes with a speed controller that supports:

- Speeds up to 16x - Bigger or finer increments (e.g. 0.1) - Default startup speed - 1-click toggle between 1x and current speed - Remembers last used speed

No tracking, no analytics. Built this for myself but figured others might find it useful.
