I've been looking for something I could host for this kind of thing - for LLM agents. Ended up on https://www.daytona.io/ as I couldn't find anything suitable to self host and realised it was a complex thing to manage. It seems Daytona is open source, including the server platform, but there is no documentation for the server element. Azure also seem to offer a service for this, it's a space that is growing rapidly.
Yeah, I know what you mean, the RAG retrieval is a bit hit and miss for me. It's better if you tag in the notes you want to refer to. But I doubt it has a team behind it like Cursor. Depending on how many notes you have, given it's markdown you could just upload them to a Project in Claude.
I really like what he's setting out to do here but I was a bit put off by the fundraising setup. If the target isn't met the donations still go to him, and there's no pledge to do anything on that case. Is that right or did I miss something?
