Diego-Andres-Hernandez/OpenJarvis ? reverse-engineered prompt

Build me a local first personal AI app called OpenJarvis that runs on my own device and starts with a simple command line chat plus a browser based desktop style interface.

I want it to be able to chat, browse local docs, do deeper research with citations, and handle a few practical assistant tasks like a morning briefing, simple scheduling style monitoring, and a code helper mode that can run tools safely. It should work offline by default with local models, but fall back to cloud only when needed. Please include a clean setup flow, a way to check whether everything is installed correctly, and a few starter presets so I can get going quickly.

Make the app feel polished and easy to use on macOS, Linux, Windows, and as a desktop app if possible. If you need to look up current docs or best practices for any of the parts, go ahead and check online.
