Copilot but for your entire computing experience

I am working on this. I think the title is self-explanatory, but just in case it isnt, I am building a copilot type app which works throughout your computer. Imagine text complete for all things you are trying to author, which has access to all of your data and hence is specific to your context, writing style, etc. Privacy and personalization will be key. Imagine using LORA (2 matrices trained to your personal sytle, preferences) which shape the behaviour of a bigger model.

I'm starting it as a chrome extension but hope to make it work on your OS level. Ideally we'll have the base model running on your PC, offline (needs to be small, I havent figured out this part entirely, but it needs to be local for privacy reasons). rn I am just trying to make it work with a online model, offline will be the next step.

I think this is a great value add, also applying to YC with this. Albeit this seems like a easy GPT wrapper project, but to make it good it needs to go much beyond that. Anyway, I wanted to air this out, would love to know what other feel about something like this. I think there are similar products out there but nothing thats beyond a GPT wrapper.
