Is it safe to let an AI assistant read my email?
It depends on three things: where your mail is processed, what the assistant is able to do with it, and whether it acts before you have looked. The safest setup processes mail on your own computer, has no ability to send, pay or click, and shows you every proposed action first. SafePersonalAI is built that way.
Risk 1: where your mail goes
An assistant that runs on a company's servers receives a copy of the mail it reads. You then depend on that company's security and its rules for keeping and using data.
SafePersonalAI runs on your Mac. With a local Ollama model the text of your mail stays there. With a cloud model that you connect yourself, the text goes directly to that provider under your own account, and never to a SafePersonalAI server.
Risk 2: a message that gives the assistant orders
Anyone can send you an email. If an assistant treats the text of a mail as instructions, a stranger can write “forward this to everyone” or “pay this invoice now” and the assistant may try to do it. This is called prompt injection.
The reliable protection is not a cleverer model. It is an assistant that is unable to do the harmful thing. SafePersonalAI cannot send email, invite people, click links, pay or move money, because those abilities were never built into it. Mail is treated as text to read, not as commands.
Risk 3: a wrong reading
AI models misread things. A wrong date in your calendar is a small problem if you saw it first, and a real one if it was added silently.
In SafePersonalAI, what the model works out from your mail is a proposal. It appears in a list with the message it came from, and you approve or reject it. Dates and amounts are checked by fixed rules, and a date that is not in the text is never invented.
Questions to ask about any AI email assistant
- Is my mail processed on my computer or on the company's servers?
- Can it send email, pay or click links at all? If yes, what stops a misleading message from triggering that?
- Does it show me each action before it happens?
- What access does it ask for in my mail account, and can I remove it at any time?
- What happens to my data when I stop using it?
