I most appreciated Complement after learning new concepts because I can use board style questions to see integration and the AI to explain cards in depth. It’s understanding rather than memorizing.

“The significantly better UI/UX compared to Anki helped me stay motivated. Card augmentation keeps things fresh and prevents pattern memorization.”

“Built-in AI chat is like having a tutor available 24/7. It helped me understand pathology concepts I struggled with for months.”

Your Anki stays yours.

Non-destructive import

We import a copy of your decks. Your Anki collection is never modified.

Study anywhere

Review cards in Complement or keep using Anki. Your progress syncs either way.

Export anytime

Download your cards and take them back to Anki whenever you want.

Med school learning tools weren't built for you.

Anki is powerful but lonely. No AI, no context, no explanations.

Making cards takes longer than studying them.

You forget why answers are wrong, not just what they are.

We built Complement to fix all of that. Gokul, Founder

Everything you need to master medicine.

AI-powered explanations and context

Highlight any term for instant definitions, chat with an AI tutor for deeper explanations, and generate practice questions — all integrated with your study flow. Students who chat after forgetting a card are 48% less likely to forget it again.
