Inbox Injection Guard Install Guide
Inbox Injection Guard, made by Thuong P. Nguyen, checks your email for concealed instructions meant to trick AI assistants. These can be written in white text, hidden with invisible characters or phrased as orders to the AI to forget its rules. It gives a verdict for each message and quotes the hidden text so you can see it.
This matters once you let any bot read your inbox, because a bot that follows a hidden instruction might forward data or reply to a stranger. The guard only reads, so it adds protection without any risk of changing your mail. Running it before your other email bots gives them a cleaner inbox to work from.
It suits owners, assistants and teams who use AI to read or answer email. Run it on a schedule before other email bots, treat any flagged message with care and report repeated senders to your email provider.
