Open Lingo
What Open Lingo is
Open Lingo is a free, MIT-licensed, open-source language-learning project built by learners. It offers structured courses with adaptive flashcards and practice for speaking, listening, and handwriting. Courses are available for Korean, Japanese, Spanish, and French, while Portuguese is in closed beta. A placement test, grammar and conjugation trainers, graded stories, and listening or role-play conversations provide different lesson formats. FSRS-6 schedules reviews according to what learners remember or forget, and Anki imports can credit words already known. Handwriting checks Hiragana, Katakana, and Hangul against animated stroke order, while speech recognition checks pronunciation. Reviews remain on the device offline and synchronize when connectivity returns. An account preserves progress across sessions and devices. The maker estimates courses at about A1 to A2 or below, says levels are not certified, and notes that courses are still growing.
