Where to get basic education on AI options?

I'm a partner in a small Colorado litigation firm. I have discovered that Claude can draft very passable motions, responses, deposition question outlines, etc. with just a few uploaded documents. This saves an enormous amount of time. Since I realized how good AI is at creating these documents, I've started down the rabbit hole of trying to educate myself on the best options while complying with all security/confidentiality requirements. So far it looks like Claude enterprise connected to our files (on Egnyte), or Copilot (we could move our files to OneDrive) would be the best options. So far I've been impressed with Claude's output, I'm just starting to play with Copilot so I'm not sure how that will compare. Is there somewhere to go that has basics as far as the best options, how to keep data safe, etc? I'm reading a lot in this sub, but only understand 20% of the lingo, making it hard to follow along. thanks!
