Burbly completely changed how I study for boards. The spaced repetition is genuinely different from anything else I've tried—I'm retaining way more with way less time. I passed Step 1 with a score I'm proud of.

Everything you wanted to know about Burbly
Burbly combines the gold-standard FSRS spaced repetition algorithm with AI-powered deck generation, social challenges, and real-time analytics—all in a polished, modern app. Unlike Anki, there's no steep learning curve. Unlike Quizlet, your review schedule is adaptive and scientifically optimized, not just a simple timer.
FSRS (Free Spaced Repetition Scheduler) is the most accurate open-source memory algorithm available. It models your personal forgetting curve for each card and schedules reviews at precisely the right time—maximizing retention while minimizing total study time. Burbly uses FSRS so you study smarter, not harder.
Yes. Burbly's AI understands context, not just keywords. It generates cards with clear questions, concise answers, and useful hints—not just copy-pasted text. You can always edit, delete, or add cards after generation, giving you full control over your deck quality.
