### Built on

KYW stands on the shoulders of open projects, and it’s a pleasure to say so.

- **FSRS** – the Free Spaced Repetition Scheduler, a community-maintained memory model. It schedules your reviews.
- **SuperMemo & Anki** – the spaced-repetition ideas it all grew from.
- **The language-learning community** – for word sets, bug reports and ideas.

Thanks to everyone who keeps knowledge open.
