What it does
DayO Book is scheduling built for real businesses, multi-staff, multi-resource, no-show tools, and customer win-back campaigns, priced at $0.50 per successful booking instead of a monthly seat fee. No bookings, no bill.
The daybook for businesses that can't afford no-shows — embeddable scheduling for salons, boarding, practices, and restaurants, priced per successful booking.
DayO Book is the daybook for businesses that can't afford no-shows: one scheduling engine for any appointment-based business — salons, clinics, studios, shops, and more.

Cancelled before the appointment time, it's never billed. Every booking builds a real customer record automatically. When a day looks quiet, don't just hope someone finds you — email the people who already know you, and let AI write the email. Don't see your business listed? Tell us what you schedule — the engine underneath is the same either way. A shared…from dayobook.com

I've built a color picker and procedural generation algorithm based on the space as well as a bunch of other fun js features and demos throughout the page that use the equations.

I trained a 125M-parameter transformer to autocomplete piano performances in real time (~108 notes/sec on an iPhone 15). The idea is basically GitHub Copilot or Tabnine, except instead of prompting it with code, you prompt it by playing a few notes on a MIDI piano. The model then continues what you played, entirely on-device. The app is free if anyone wants to try it. Happy to answer questions about the model, training, Core ML, or the many things that didn't work.
