Keelo

Keelo turns the words and expressions you don't know into ready-to-study Anki flashcards — no manual card-writing required.

How it works
1. Capture a word or expression you just ran into — in either language you're learning.
2. Keelo's AI drafts a complete flashcard: translation, definition, example sentences, a cloze sentence, grammar notes, and pronunciation.
3. Review and edit the draft, save it to a deck, then export straight to Anki.

Built for real studying, not another app to juggle
Keelo doesn't reinvent spaced repetition — it feeds the tool you (or millions of learners) already trust. Export any deck as a ready-to-import .apkg file and open it in Anki Desktop, AnkiDroid, or AnkiMobile. Every field maps automatically; nothing to configure.

Your AI key, your control
Keelo uses your own API key from Claude (Anthropic) or GPT (OpenAI) — whichever you already have. Your key is stored only on your device, sent directly with each card request, and never saved, logged, or seen by Keelo's servers beyond that single request. No Keelo subscription, no markup on AI usage — you pay your provider directly, at their rates.

Organize your way
Create as many decks as you like, one per language pair or topic. Swipe to delete, edit any card after the fact, and track your daily capture streak.

Available in English, Portuguese, Spanish, French, and German, with more languages on the way.

Keelo is currently in beta — features are actively evolving based on real study habits, and we'd love your feedback.
