I left Google earlier this year and created Dyad, a local, open-source AI app builder made with Electron.

The motivation: I tried one of the popular cloud-based AI app builders, but when I pulled down the app to run locally and debug in Cursor, it just didn’t work. So I created Dyad, an app builder that runs fully on your computer, making it easy to switch between Dyad and coding tools like Cursor or Claude Code.

I've gotten questions about how it works under the hood so I wrote an architecture doc explaining how it does tool calling using XML tags, etc: https://github.com/dyad-sh/dyad/blob/main/docs/architecture....

Let me know what you think and happy to answer questions about building an Electron app, etc!
