Osmolog - Language Immersion Tracker

Track active and passive immersion across video, custom websites, and Anki reviews, with no account required.

Track language immersion across streaming video, Anki reviews, MPV, Manatan, Steam games, and everyday study—all in one private dashboard. Osmolog separates active immersion from passive background listening. Once set up, supported playback is tracked automatically, so you can focus on the language instead of a stopwatch. • Automatic active and passive tracking for YouTube, Netflix, Twitch, and Crunchyroll • MPV, Manatan, and Steam tracking through Windows Osmolog Companion • Anki review time through Osmolog Connect • Custom video websites and optional experimental providers • Manual entries for reading, conversation, gaming, and offline study • Phone tracking with a free confirmed account—even while your computer is off • Goals, streaks, calendars, and language insights • Groups and Pairs, with account requirements shown in the app • JSON backups and CSV exports Optional language detection for Netflix and Crunchyroll processes audio locally without uploading recordings. Local tracking needs no account. Basic Chrome Sync shares totals and preferences; full-history cloud backup requires Pro. No ads. Analytics and error reporting are off by default.
