Select a word right inside the page you're reading — a definition matched to this exact sentence appears instantly, with pronunciation, real examples, and a picture when one helps. It's saved to that book's own word list automatically, no separate step.
Most e-reader dictionaries give you a flat list of every possible meaning and leave you to guess. Dictarium's desktop reader matches the definition to the sentence you're actually reading, adjusts for your own level, and — if the page is a scan with no selectable text at all — recognizes it first, so you can look up words on that page too.
Ya no sabía si podía confiar en él después de todo lo que había pasado.
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.
A built-in e-reader dictionary answers one lookup and forgets it. Dictarium keeps a running word list per book, with the exact sentence each word came from, so revisiting a book later shows you exactly what you already worked through — and every word feeds the same dictionary as everything else you look up, on any device.
See every book you have added, how far you have gotten, and how many words you have saved from each one — all stored on your own device, ready the moment you open the app.
Dictarium's desktop reader opens your EPUB and PDF books and looks up any word instantly — with a real definition, pronunciation, and a running vocabulary you can turn into a dictionary.
