Jaggo is the reading companion for language learners. Hit an unknown word while reading? Look it up, save it, and Jaggo drills it with matching lessons until it sticks — in any language.
No bloat, no gamification treadmill — just the tools that actually help you remember the words you read.
Add any word you encounter while reading. Jaggo stores the word, its translation, and the context in which you found it — all searchable and editable, in any language.
Match words to their translations in a fast-paced card game. Harder words appear more often so your weak spots get extra practice.
Type any word and get instant translation suggestions from our AI. Review and accept the one that fits your reading context, then save it to your dictionary.
No ads, no selling your data. Your word list syncs to your account for backup — and you can delete your account and all your data at any time.
Reading a book and hit an unknown word? Open Jaggo, type it in, and the AI suggests a translation. Tap save — done in under ten seconds, then get back to your book.
Jaggo picks words from your reading dictionary and presents them as a matching game. Sessions take 2–5 minutes and focus on the words you find hardest.
The more words you save and review, the more you understand on the next page. The stats page tracks your progress and highlights words that still need work.
