Small apps I build for the children in my life, with AI, in a few evenings each. They are working prototypes: all the content is original, they run on a phone, and they keep nothing except what your own browser stores. Use them freely.
Tiny Bow
2026
For a four-year-old at pre-twinkle, and a parent who can't read music
A practice companion for Suzuki violin. Each skill gets an original chant, story, dance, and a five-minute guided session; the printable sheets include a coloring page and a skill ladder. No sheet music or recordings, only piece names.

2026
For a child learning to read, one letter at a time
Phonics words and short stories that grow as each new letter is learned, so everything on screen is readable with the letters the child already has.

For a fifth grader in Taiwan who learns best in small steps
Math practice built on Kumon ideas: six topics in five small steps each, ten timed questions per step, repeat until fast and accurate. A dragon that grows with stars, a wrong-answer notebook with worked solutions, and stickers to collect.

Each app opens best on a phone, and can be added to the home screen from the browser's share menu. Case studies on how they were made will appear under Work as they're written.
