SendChallenges
Send paid challenges. Prove them on video.
What it does
SendChallenges lets anyone send a challenge link with a reward attached. The recipient can accept it, complete it and prove it on video. What makes it different is the loop: challenges become content, content creates new challenges, and creators can let their audience decide what they do next. We’re starting with creator-fan interaction, but the same mechanic also works between friends and through a public challenges marketplace.

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.
