VocabCatcher

Capture, translate, review, and sync vocabulary from any page, YouTube video, or Short.

VocabCatcher turns every web page and every YouTube video into an English lesson. Select a word or a sentence anywhere and see its meaning, pronunciation and real examples at once. Save it, and VocabCatcher brings it back at the right moment so it stays in your memory instead of fading after a day. Translate into 128 languages, from Arabic, Urdu, Spanish and French to Hindi, Turkish, Indonesian, Swahili and many more. WHAT YOU GET • Instant lookup Select any English word or sentence to see definitions, IPA phonetics, examples and natural audio pronunciation, with the meaning in your own language. • YouTube and Shorts captions that follow the speaker Captions appear line by line, the way they do on Netflix, and break at natural pauses instead of at random points. Every line stays long enough to read. Show dual subtitles, blur the translation until you hover, adjust the position, size and colours, and fine-tune the audio sync. Captions step aside while YouTube shows its seek preview, so they never cover it. • Spaced repetition that fits your browsing A 5-stage review (Learning, Familiar, Solid, Strong, Mastered) brings words back as small bubbles while you browse. Words you miss come back sooner but never lose the progress you made. Each word shows its stage and how common it is, from Basic to Advanced. • Your words, your way Several meanings appear as clean separate cards. Edit any meaning, import word lists from TXT files or pasted text, and review in the popup whenever you like. • Cloud sync and the VocabCatcher website Sign in once to keep your words, archive and progress on all your devices. The companion website adds a learning streak, leaderboards, a media library, an Explore section, a placement test and an optional AI coach. • Streak that rewards real learning Your streak counts reviews, bubbles and new words, and stays honest for cloud users with a quick visit to the website at least once a month. • Your data stays yours No ads and no tracking. You can delete your cloud account and everything stored in it, right from the extension or the website. • Made to be comfortable Dark and light glass themes, adjustable transparency and text size, and a fast, light design that never gets in your way.
