Features & roadmap
This is a free study tool. Every feature is open to everyone — no paywall, no usage caps. Here is what already works, and what is being considered next.
Available now
Full grammar library
All 955 grammar points from N5 to N1, filterable by level, type and study status.
Analytics & review insight
Study progress, level breakdown, retention curve and weak-grammar tracking.
Personal library
Add as many private grammar entries as you like and hide defaults you don't need — no limit.
Cloze practice
Questions generated from example sentences, scoped to today's, studied, or all grammar.
Planned
Mistake notebook
Collect the grammar you miss in practice so you can drill it on its own.
Import & export
Bring in personal grammar via CSV / JSON and export your study data as a backup.
Better mobile flow
A study flow tuned for phones, and exploring offline support.
Continued content work
Ongoing proofreading of examples and more contrast notes for confusable grammar.
These are directions, not commitments — no fixed timeline yet.
Support the project
All features are free. If it helps your JLPT prep, you can buy the author a coffee — entirely optional, and it unlocks nothing.
