Cucaracha is a spaced repetition app for learning things and actually keeping them. You make cards, or let the AI build them for you, and Cucaracha schedules each review for the moment you are about to forget. A few minutes a day is enough to hold onto what you learn.

Yes. Reviewing your cards is free forever, with no daily cap and no paywall on the part that makes memory work: showing up each day. That stays free for life. Pro is only for the AI features layered on top.

Pro is the AI. Unlimited AI card generation from whatever you are studying, AI editing and cleanup of your decks, and the tutor for when an idea will not click. Your reviews and the cards you already have stay free either way.

Your cards are yours. We collect as little as we can, store data in the EU, and never sell it. For the full detail on what we keep and why, read the privacy policy.

Send us a note with the contact form above and we will get back to you. If you have an idea for the app, the feature board is the best place to share it and vote on what others have suggested.
