SanojaSanojaSelect or double-click any word on the web. Sanoja translates it between English and Finnish, reads it aloud, and saves it so you can review it later — for free, with no account and no tracking.
Vocabulary that shows up while you're already reading something you care about sticks a lot better than a word list.
Select an English word and see it in Finnish, or a Finnish word and see it in English — detected automatically, no language picker.
Click the speaker icon to hear the Finnish pronunciation, using your browser's own text-to-speech — always the Finnish side, since that's the point.
Every word you look up is saved automatically. A Leitner-box quiz brings words back at increasing intervals until they actually stick.
Get a word right consistently and it graduates out of active review into a "known words" list — progress you can actually see.
Works reading English or Finnish, and remembers everything you've looked up. Scroll or use the arrows to see more.
Double-click an English word — or highlight a short phrase — and a small card pops up with the Finnish translation. No popup windows, no switching tabs.
Select a Finnish word on a Finnish-language page and Sanoja shows you the English translation instead — detected automatically, no language picker.
Every word you look up gets scheduled for review with a Leitner-box spaced-repetition system — get it right and it comes back in 3 days, then a week, then longer.
Search, sort, and export your full word list any time, with a separate collapsed section for words you already know well.
Switch to the word-cloud view for a quick visual sense of what you've been reading — the bigger the word, the more often you've looked it up.
Turn the extension on or off, or enable automatic pronunciation every time you select a word, right from the toolbar popup.
