DEVONthink vs MS Copilot with OneDrive

I am a longtime DT user, but started recently considering to move all my files to OneDrive to user the natural language search of Copilot, auto-summary and other powerful features., which are amazing. I am not the biggest fan of MS, but I am not aware of any other tool from Apple or Google that offers something similar. Not to talk about DT. Does anyone have experience with such a move?
