Do you use LLM/AI with your #Obsidian vault? If yes, which tool or plugin can you recommend, and why?

Please note that I'm actually looking for *recommendations* – not random picks from the pile, or drive-by search results 😉 Thanks!

@czottmann @hmans Copilot, integrates with my vault, with specific notes or can be used for research. Simple to use.
@csbronit @hmans Thanks! Your vault is in your OneDrive, I take it?
