Recursio: Learn English

Learn English vocabulary and grammar — and actually remember it. Recursio is a focused English practice app with your own word list, grammar by topic, spaced repetition, and an AI coach.

Recursio helps English learners stop forgetting the words and grammar they already study. Instead of a fixed course, you choose what to learn — useful words, grammar topics, sentence and speaking practice, and Coach sessions — and Recursio brings your weak spots back into review, right before you forget.

Best for learners who can already work in English at a basic level. Definitions and examples are shown in English, so you practice inside real English instead of translating.
