AnkiTov

Why do students forget what they learned last week? Memory decays on a predictable curve, and school schedules rarely schedule timely reviews. Cognitive science has long proven that spaced repetition (SRS) interrupts that forgetting curve and produces durable long-term retention.

AnkiTov is an open-source, self-hosted classroom layer on top of proven spaced repetition: import standard Anki decks, assign them to your roster, and let students review in any browser. It runs on one small server — in the cloud or on your school's own hardware — with zero student PII, zero third-party trackers.
