Import any text dataset, build a custom tokenizer,
configure a transformer model, and train it — all
from one app. Built for Apple Silicon using Metal.
Free tier lets you explore the full workflow and
train single-layer models. Pro unlocks unlimited
layers for production-quality models.

Rapidscall
Hi. I am releasing Rapidscall today. It is made for training AI on Apple Silicon. Try training today. It is free to download. I would love to hear what you build and what gets in your way.

Rapidscall started as a personal learning project and became a tool for anyone who wants to build their own model — on their own terms, on their own machine. Apple Silicon made it possible. Metal and unified memory mean a MacBook Air has genuine training capability. I wanted to make that accessible. Happy to answer any questions about the app or training process.
