- [Tutor](https://rossmiller.dev/tutor/): AI tutor that writes books for you, answers questions, and tests your understanding. Open source: https://github.com/rsml/tutor.

## Case studies

- [Chord Colors](https://rossmiller.dev/craft/chord-colors/): How an interactive encyclopedia of music theory teaches with color instead of sheet music.
- [Tutor](https://rossmiller.dev/craft/tutor/): How an AI tutor writes personalized books that adapt to how you learn.

## Writing

- [Making illegal states unrepresentable in TypeScript](https://rossmiller.dev/writing/making-illegal-states-unrepresentable/) (2026-06-25): Using the type system to shape AI-generated code instead of grading it after the fact, so whole classes of bugs cannot be written down.
