Osmolog: An Exposure Tracker for Language Learning

Why it surfaced

Osmolog separates active viewing from passive listening, identifies languages from audio, captions, and player data, and remembers corrections for recurring channels or series. Its history stays on your computer, and the unusually candid homepage explains the whole mechanism as a one-person learner's attempt to replace manual stopwatch discipline.

A Chrome extension that automatically tracks the languages you watch and hear across YouTube, Netflix, and Twitch.
