How do I incorporate AI into my workflow without compromising my clients’ privacy and confidentiality?

I see AI use as giving away my clients’ proprietary info, and I fear legal repercussions for using it in my service-based business as a virtual assistant. However, I also fear that not using AI in any capacity is holding me back. I don’t think clients will work with me if I let AI read our emails or incorporate it into workflows that use their proprietary data. But I get burnt out easily and need to do something about it. How do I incorporate AI in a way that honors client confidentiality and doesn’t share sensitive client info with a third party?
