The science

Built on what actually works

Both Revu Classic and Revu Web are built on the same research foundation — two of the most robust findings in learning science, not trends or hype.

Retrieval practice

Testing yourself on material, not re-reading it, is rated as a high-utility learning technique. It improves long-term retention across materials, contexts, and learner types.

Dunlosky et al. (2013). Psychological Science in the Public Interest.

Spaced repetition

Distributing practice over time, instead of cramming, is also rated high-utility. FSRS, the algorithm Revu uses, optimizes review timing based on your actual recall performance.

Dunlosky et al. (2013). Psychological Science in the Public Interest.

Revu Classic implements FSRS locally. Revu Web extends it with AI-generated retrieval practice, pedagogical session arcs, and calendar-aware scheduling.
