Then a quiz on what you missed.

Pebble writes it from your own cards, aimed at the ones you got wrong: multiple choice, pick all that apply, true or false. It’s marked the moment you submit, with the why.

Yes. Inline and display maths in any question or answer, rendered the way your notes are. Code blocks get syntax highlighting, and your phone gets a maths keyboard for writing them.

Your own subjects, chapters and cards, your results on them, and the PDFs you hand him. Nothing from anyone else’s library. Every read shows as a line in the chat, so you can see what he looked at.

Every card he writes is a draft you review before it lands; nothing goes into your library unread. Ask him to check any card and you get a verdict and a suggested fix, free. You still press Save.

A card Pebble writes and you keep costs 1 credit, a quiz question costs 1, and a PDF costs 1.5 a page, rounded up, with a minimum of 3 (up to 60 pages). Checking a card is free. Free accounts get 25 credits a week, Pro gets 300, and unspent credits stack up to three weeks’ worth. In a duel, only the challenger pays.

Really. No card, no trial countdown. Unlimited cards, training, statistics, sharing, and Pebble with 25 credits a week. Pro is the same Pebble with 300.

In the first quarter of 2027, on iOS, Android and the web at the same time. Waitlist members get invites first, in signup order.

CSV import ships at launch. An Anki (.apkg) importer is in the works: your review history won’t carry over, but your cards and decks will.

Both. The app and Pebble speak English and French, and you can switch whenever you like.

Your subjects are private by default; you decide what’s shared with friends or made public. Pebble only sees your own library and what you send him, and we never sell your data.
