Find real contacts & write cold emails in 10 seconds
What it does
ColdPitch finds verified contacts at any company and writes a personalized cold email for each one. The whole thing takes about 10 seconds. Type in a company → get real contacts (name, title, email) → get a personalized cold email ready to send. You can also generate a 3-email follow-up sequence with one click. Cold email research normally takes 20+ minutes. We compress it to 10 seconds without sacrificing quality. Free plan available. No credit card required.

I trained a 125M-parameter transformer to autocomplete piano performances in real time (~108 notes/sec on an iPhone 15).

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.

The whole model is a single 14MB binary that runs a full session in 28MB of RAM; 45m parameters at 2bit compression. Needle hits 500 tokens/sec decode speed on a Raspberry Pi 5, sits between 400-1,500 tokens/sec on VR devices like Meta Quest 3S and Apple Vision Pro, and ranges…
