For reading

Stop switching tabs to look up a word

An article, a forum thread, documentation for a tool in another language — select a word or phrase anywhere on the web, and it's saved with the sentence around it, in the same dictionary as everything else you're learning.

How it works

Select it, and it's already saved

The browser extension works on any page, not just a fixed list of supported sites. Select a word, tap the button that appears, and it lands in your dictionary along with the paragraph it came from — so you never lose the context that made it click.

Mark it, and it plans the next review itself

After each card, just say whether you knew it. Dictarium uses that to steer review time toward the words you’re actually shaky on, not the ones you’ve already got. Want more nuance? A 4-point scale — Again, Hard, Good, Easy — is one toggle away in settings.

Hear it the way it’s actually said

A word doesn’t sound the same everywhere — Dictarium gives you real voices to choose from instead of one flat default: American or British English, Latin American Spanish, Brazilian Portuguese, and more. Pick the one you want once, and every card plays it back that way from then on.

Not a copy-paste translator

A translator tab gives you an answer and forgets you asked. Dictarium turns every lookup into a dictionary entry you'll actually review again — so the fifth time you hit the same word, you already know it.
