Hachimo

Hachimo gives Japanese English learners continuity across ChatGPT sessions: it saves agreed lesson results, vocabulary, and recurring mistakes to a private learning memory, turns them into spaced-repetition review, and keeps a personalized 5–15 minute daily plan and progress record.

Hachimo only reads and writes your own learning data: today's plan, lesson records, review cards, practice activities, progress and learner profile. It previews a lesson before saving it, never reveals a review answer before you try, and does not access your email, calendar, files or chat history.
