AI-Based Search

I would love to see an AI-based chat tool for searching ACROSS all of my notes with responses that reference relevant notes. The quick-open menu could be supercharged with AI-based chat features like mem.ai or Evernote's AI-Based search. A few examples I can think of:

1. Q: "What notes do I have related to X topic?" Response: a list of relevant notes back (preferably with back-and-forth interaction to hone my search).
2. Q: "I am starting a new project about X, what do I already know that would be relevant to this project?" Response: a detailed response and links to relevant notes that I could quickly save to a new note
3. Q: "What is the next most important task for X project?" Response: the task with the highest point score from my note for that project
4. Q: "Where am I staying in Chicago next week?" Response: The specific answer based on my note about my trip planning to Chicago next week.
