Our story

Built by a student,
for students.

Computus started as one student's answer to a simple frustration: the best math tools were locked behind paywalls, logins and installs. So we built our own — 150+ tools, free for everyone, forever.

Every solver, every plotter, every lab was crafted with a coding agent as a pair-programmer — proof of what curious students can build today.
