How it works
Open any Japanese video with subtitles. Glosaire sits beside the player — no separate app to juggle.
Pause on a word, see reading and gloss instantly, and drop it into your deck when it matters.
Practice pulls the same sentence you saw on screen, so every drill is tied to a real memory.
Interactive demos
These snippets use the same UI as practice mode, with local demo data only.
Hover readings, POS, and glosses exactly where they appear in the line.
