HOW IT WORKS
Three steps, and none of them is “open another app”.
1
⌘ + Shift + K
Capture what you're reading
Drag over any Japanese on screen — an image, a video subtitle, a PDF. Kana Lens reads it and breaks the sentence into words and particles.
見

One tap
Save the ones that matter
Every word in the breakdown has a Save button, with the sentence you found it in. That context comes back later when you're reviewing.
留

New tab
Review without deciding to
Your queue is already there when you open a tab. Answer a few, and the grid updates with what you actually recall.
習
YOUR NEW TAB
The study room opens itself.
Kana Lens takes over the Chrome home page. Every new tab is a nudge: what's due, what's shaky, what you've mastered — colour-coded by how well you actually recall it.
✓
Weakest first
The queue leads with the kanji you keep missing, not the ones you added last.
✓
Colour is memory
Green is mastered, violet solid, amber shaky, grey untouched — legible at a glance.
✓
Counts you can trust
Times seen on pages sits next to times recalled correctly, per kanji.
Kanji to meaning tests recognition. Meaning to kanji tests recall — the harder direction, and the one that tells you whether you really know it. Kana Lens shuffles both across your whole list.
✓
Every kanji in your list is fair game — no scheduling to babysit, no cards piling up.
✓
Wrong answers show the reading and the sentence you captured it from.
✓
Each session updates the recall percentage behind every tile.
