Is it safe to give an AI access to your email? Prompt injection explained
Prompt injection, permissions, read-only access and drafts: what can go wrong when an AI reads your mail, and how to limit the risk before you connect.
Shared memory and privacy for your AI assistants
Giving an assistant access to your email or your messages raises fair questions. What can it read, what can it change, and what happens if a message contains instructions written to trick it? This category answers them plainly. You will find how prompt injection works and how to limit it, how to choose which tools an assistant is allowed to see, and why some sources such as Telegram are connected read-only. It also covers the shared memory Fezola keeps for Claude, ChatGPT and your other assistants: one place where useful facts are stored, which you can read, edit and erase at any time. By default, replies are created as drafts and never sent. Start with the article on giving AI access to your email safely.
