Also a Chrome extension [0]! The concept is to use the browser's context menu to run commands on the LLM, so it stays out of your way most of the time but feels like a somewhat native experience.
The stack is: 1. TypeScript/Node/tRPC/Postgres/Redis/OpenAI on the backend 2. SolidJS/Crxjs/tRPC on the front end 3. Astro for the docs/marketing site
And deployment is currently through render.com for the databases and servers, and manually via a zip file to the Chrome webstore for the extension itself.
