Is anyone building an LLM based digital surrogate?

I’ve toyed with the idea of building a digital assistant/surrogate to handle most of my coordinating Dr. appts, negotiating bills, inquiring about trash/medical/home/car services and generally just being a proxy between myself and my non-friend interactions.

Is anyone working on this or having any luck using any services like this? I’d pay $100s/month for this but don’t have $100,000 or 12 months to invest in an MVP unfortunately
