A YouTube video, a work call, a page you’re reading, an old Anki deck you never finished — Dictarium pulls words in from all of it. One dictionary, reviewed with practice that adapts to what you actually remember.
Free · no card required
However a word reaches you, it ends up in the same place — reviewed together, not scattered across five apps you never open.
Highlight a subtitle on YouTube — the word, its meaning, and the exact line it came from are saved instantly.
A call, a lecture, a show in the next room — the desktop app transcribes it live, tap a word to save it.
Select a word or phrase anywhere on the web with the browser extension, and add it straight to your dictionary.
Import an Anki deck or a CSV — bring years of flashcards in instead of starting over.
No source yet? Ask for a dictionary on any topic — "kitchen Spanish," "business French" — and get one instantly.
Watching something on YouTube, hit the capture button the instant you hear a word you don’t know — Dictarium grabs the subtitles around that exact moment, timestamped so you can always jump back to the scene. YouTube works today; Netflix and more platforms are next.
An article, a forum thread, documentation for a tool you’re learning in another language — select a word or phrase anywhere, tap the button that appears, and it’s saved with the paragraph around it. Same extension, same dictionary, just not tied to a video.
A call, a lecture, a show playing in the next room — the desktop app turns whatever’s on into a transcript in the background. Select phrases from the transcript yourself today; generating a whole dictionary straight from the conversation is next.
Every dictionary and tag gets scored by what’s overdue and what you’re actually struggling with. Sessions are built to avoid mixing look-alike words — the thing that really hurts recall — so opening the app, the next practice is already picked for you.
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.
Make a dictionary public, and other learners can bookmark it. Someone else’s dictionary for the show you’re already rewatching is the fastest way into new vocabulary.
