24 alternatives to EGUARD
After seeing sophisticated phishing attempts slip through Gmail's filters, a friend and I built a browser extension that uses local AI to analyse emails for threats.

Even if you're not comfortable installing it yet, we have screenshots showing how it works. https://www.eguard.app https://chromewebstore.google.com/detail/eguard/dnpofinmilhb...

Hi everyone, My motivation for building this was to address the trouble of mass unsubscribing from unwanted emails and deleting bulk emails while ensuring privacy and control over the process. With this Chrome extension, emails are not sent to any external servers. All calls to the Gmail API happen locally on your device. Feedback and suggestions are welcome!
