Small products for real problems
This site is a notebook of small, concrete products — tools built for real, everyday problems, mostly around helping kids turn screen time into practice time.
Here you'll find the products themselves, and a blog where I write down the thinking behind them.

Kid Typing & Recitation Practice

Kid Typing & Recitation Practice

A web app that helps kids practice typing, recite classic articles, and learn English — all at the same time. It tries to make kids 'addicted' to something useful that used to be boring, and to turn as much of their screen time as possible into practice time.

Audio Repeater

Audio Repeater

A desktop tool that automatically cuts a video's audio into sentence-sized pieces. No more fiddling with A-B loop points — just click a piece to repeat it. My son used it to recite the entire transcript of The Lion King.
