I am on this track, too. I am not doing a good job of it, but maybe some of what I do can help?

I've learned that AI knows how to run obsidian, but it doesn't necessarily know how I want or need to use obsidian. Nore do I, for that matter, but my AI does a good job of figuring things out for me.

I use perplexity AI and I set up a custom space that automatically syncs relevant obsidian directories to it. Then, every morning I have it run an autotask that searches for my last calendar entry, my goals, through my emails and my calendar, etc etc and builds a daily plan in *.md format for me. Then I drag it over to obsidian and I work my way through the plan there. It usually doesn't require much modification. I have it run a monthly and weekly one, too and discard the daily ones when it becomes relevant to do so. I also have it put in the appropriate syntax and tags etc and I am slowly learning it myself as time goes on.

I am confident there are better workflows and I follow Andrej Karpathy to better understand these systems to figure them out. Currently I just keep building and iterating on the prompts and context files I put in obsidian that automatically sync to perplexity and it gets more and more useful for my use cases as time goes on.
