Science-Based Learning Platform

Master Anything with Intelligent Spaced Repetition

Square combines advanced learning algorithms with modern course creation tools to help educators build courses that students actually remember.

Without SquareWith Square

Most Students Forget 90% Within a Week

The Ebbinghaus forgetting curve shows that without reinforcement, memory retention drops exponentially. Traditional learning platforms ignore this fundamental problem.

70%

Forgotten in 24 hours

Students lose most learning within a day without reinforcement

90%

Forgotten in 7 days

Nearly all learning vanishes within a week using traditional methods

$1.5T

Wasted annually

Global spending on ineffective learning that students forget
