Sanoja turns the pages you're already reading into Finnish practice. Select or double-click any word on any webpage — English shows you Finnish, Finnish shows you English, detected automatically. Hear it pronounced, and every word you look up is saved into a spaced-repetition word list so it actually sticks, with mastered words graduating into a separate "known" list. No separate app, no tab-switching — just the page you're already on. Free, open source, no account, no ads, no tracking.
