What it actually is
Covers 14 languages along an explicit CEFR path, and its best feature is the community exchange: you submit short writing or speaking exercises and real native speakers correct them, free of charge, in exchange for you correcting theirs. The free tier is limited to core lessons; Premium unlocks grammar, offline and the full path. A solid Babbel alternative if you specifically want writing practice with human feedback.
