In their own words
Jambo
Jambo is a flashcard app for language learning and exam revision, with spaced repetition, translation, and AI-assisted card creation. Its Slam review schedule uses fixed intervals of 1, 3, 7, 14, and 30 days. Card generation can start from a prompt, pasted text, a URL, or an uploaded PDF. The built-in Translator supports 30 languages and can save results to a selected deck; free translations use Gemini, while paid tiers also offer DeepL for longer translations. Every tier supports CSV export, and Sushi adds Anki.apkg export with spaced-repetition progress. Coffee and Sushi include ElevenLabs audio plays with daily limits. Class Mode lets teachers share decks with students invited by email, and updates preserve student progress. Jambo is available on Android, iOS, and the web, and the maker says there are no ads on any tier. The free plan allows 2,000 cards, 15 decks, five AI generations per day, and 100 translations per day. A 14-day trial is also listed.
