Every AI a**istant wants to read your email now. Gemini can summarize your Gmail, Copilot can draft replies in Outlook, and Apple Intelligence can surface what it thinks is important. And almost universally, to do any of this, they have to have complete access to your entire inbox. And that means all of it. Even if you want to incorporate an external cloud-based LLM with your email, you likely need to give it OAuth access to your account, so it can access everything as well.
