Complement

The idea behind Complement

Learning should
stay with you.

We’re building the place where understanding becomes lasting knowledge. It started with our own experience of learning medicine.

Why we started

Knowing the answer
is just the beginning.

Medical school asks you to learn an extraordinary amount. Spaced repetition makes that possible. But when a card doesn’t make sense, repeating it only gets you so far.

Complement brings explanations, questions, and practice into the same place as your cards. You can stop at the idea you don’t understand, explore it, and return to studying with more than an answer to memorize.

Our first community is medical students. Our ambition reaches further: a platform that helps anyone build knowledge over a lifetime.

“The core of Complement is going to stay free. Anyone who’s studying should be able to use this.”
