What you get
FSRS, the open memory model, brings each word back just before you'd forget it, fitted to your own reviews after a few hundred of them. Memory shows how much you could recall today and the day you reach your target, so the months to N1, HSK 5 or B2 are a line you can read, not a feeling.
Current 78% · target 90% · about 24 more days
Every session is the words that fit the minutes you set. Come back after a missed week and it's the same size: the words you've started to forget come first, and new words wait until the old ones fit. The advice everyone gives, turn off new cards until the pile goes down, happens by itself.
10 minutes a day · the Relaxed pace
Every card reads aloud in your phone's own voice: the front, the back, both, or hands-free with the volume keys on a walk. Generated clips in a natural voice come with the vocabulary card and Convert to audio, and they stay on the card, so they play offline too.
Read aloud · free, offline, hands-free
The vocabulary card fills its own reading, a spoken clip, an example sentence with its clip, and a picture where one fits, for you to check before you save. Words in context, not isolated. Twenty are free, then it's a Plus feature; a card from anywhere takes four taps.

Fair questions
Honest: not at launch. What it has: a card from anywhere in four taps, paste a list to make cards at once, import any Anki deck, and a vocabulary card that fills its own reading, clip, example sentence and picture from the word.
Read aloud reads every card in your phone's own voice, free, offline, hands-free if you like. Generated clips come with the vocabulary card (20 free, then Plus) and Convert to audio (25 free).
Import Core 2k, Kaishi or any Anki deck with its audio and history. The shelf holds shared decks and Bunshu's own originals, Kanji N5 among them, free.
Cards and reviews are free and unlimited on every plan, with no ads, in writing, and export is always free. Plus sells unlimited AI, not the basics.
No. Your session stays the size you set, the words you've started to forget come back first, and new words wait until the old ones fit. No queue to clear.
In writing
