HOW IT WORKS

Three core features.

01
CORE FEATURE

AI Generation

Drop a lecture PDF. Chippy generates focused, exam-ready cards while you grab coffee.

02
CORE FEATURE

Spaced Repetition

Powered by an enhanced SM-2 algorithm (the same science behind Anki), Hamstr schedules your reviews so you remember more with less effort.

03
CORE FEATURE

Make Cards

Build your own cards manually. Your format, your wording, your way.

FEATURES

Everything you need. Nothing you don't.

AI Cards in Seconds

Drop a lecture PDF. Chippy uses leading reasoning AI models, guaranteed, to generate focused, exam-ready cards in seconds.

Spaced Repetition that Works

SM-2 scheduling with learning steps. Review what's due, skip what you already know.

Repeat Cards Your Way

Choose how often cards come back, so difficult cards show up sooner and the ones you know stay out of the way.

Ready in Seconds

No plugins, no config files, no learning curve. Open the app, drop a PDF, start studying. That's it.

Anki Export Built In

Already use Anki? One click sends your deck to AnkiConnect with tags intact.

Tag-Based Review

Auto-tagged by lecture and topic. Drill one chapter or the whole semester.

BUILT BY A STUDENT

Hamstr was made because other flashcard apps don't work.

Flashcards work, but it shouldn't take weeks to learn how to use a flashcard app effectively, or force you to settle for one that doesn't help you learn. Hamstr takes the best parts of every flashcard app and brings them together in one simple, workable app anyone can use. And since making flashcards takes too long, Hamstr lets AI make them better than any human could.

FAQ

Common questions.

Is Hamstr only on Mac?

Yes, Mac first. Windows and browser versions are on the roadmap.

Do I need an Anki account?

No. Hamstr has its own built-in review system. Anki export is optional.

What happens if I cancel?

You keep all your cards and can still review them. AI generation pauses until you resubscribe.

Is my data safe?

Cards are stored securely in the cloud tied to your Google account. You can export anytime.
