From YouTube videos, work calls, articles, and old Anki decks — Dictarium saves every word automatically in one dictionary, then brings it back with spaced-repetition practice until it actually sticks.
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.
Reading an EPUB or PDF in the desktop app? Select a word without leaving the page — even on a scanned PDF.
Drag to select a word or phrase directly in the subtitles while you watch — a definition appears right there, with the exact line it came from saved alongside it. Works on YouTube and Netflix today; more platforms are next.
No puedo creer que perdamos la casa así.
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.
Open an EPUB or PDF in the free desktop app, select a word without breaking your reading flow, and get a definition matched to that sentence — even on a scanned PDF with no selectable text at all.
Ya no sabía si podía confiar en él después de todo lo que había pasado.
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.
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.
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.
No — Spanish is just the example used throughout this page. Dictarium works the same way whether you're learning Korean, German, Portuguese, or anything else.
Yes. Creating an account, capturing words, and practicing with spaced repetition are all free, no card required.
Netflix and YouTube for video subtitles, plus any webpage for reading — on Chrome-based browsers today.
The web app alone covers your dictionary, practice, and stats. The extension is what lets you capture words directly from Netflix, YouTube, or any page as you go — add it whenever you're ready.
