Welcome to Mentis!

Mentis isn't your typical flashcard app. We built it to be completely customizable - use it however YOU want to learn!

Scientifically Proven Memory System

We use the SM-2 spaced repetition algorithm - a smart reminder system that shows you flashcards right before you'd forget them. Instead of cramming, you review cards at perfectly timed intervals (1 day → 6 days → weeks → months), making memories stick permanently with 90% less effort.
