Learn a language from your own mistakes
Langu remembers every word you got wrong, schedules it for exactly when you're about to forget it, and generates the next lesson from your gaps — not from a generic word list. Spanish first; built for any language, in any script, in any direction.
Spaced repetition
A proven review schedule shows you each word at the edge of forgetting. Struggling words come back soon; solid ones drift weeks out.
A content factory
Cards, quizzes and reading pitched at the words you actually know — from a topic, a pasted passage, or a raw word list.
A grader that explains
Free-text answers judged on meaning, not on a missing accent — and every correction explained and filed in your mistake journal.
