A study platform that pairs structured courses with flashcards. The SM-2 algorithm schedules reviews at the right intervals so material sticks. Slides-style lectures break topics into single concepts with keyboard navigation.

The challenge

Most study tools either store flashcards or host courses, not both. Learners lose progress switching between apps and review material at the wrong time.

The solution

We built one platform where courses, lectures, and flashcards live together. The SM-2 algorithm sets the next review date for each card from recall performance. Progress tracking covers courses, lectures, and card mastery, and a request system lets users ask for new course topics.
