Japanese learners lack flexible, trustworthy practice between lessons
Self-directed Japanese learners want to revisit material, reinforce memory, and supplement their current studies without starting over in another service. Some find lesson reviews too limited, while making useful vocabulary decks—with readings, pitch accent, and varied fonts—can be cumbersome enough that they return to pen and paper. Trust in automated instruction is also a concern, though pronunciation, translation, and other requests point to needs beyond a first version of a study companion.
For self-directed Japanese learners using language apps. Mentioned from Feb 2024 to Jun 2025 on Bluesky and Hacker News.

Is there an app for learning Japanese that let's you go back and retake or redo a lesson plan because Duolingo isn't cutting it with my memory retention issues
making new decks with readings, pitch, different fonts etc is a pain in the ass. So back to pen and paper
