YOUR AI EMAIL SAFETY ASSISTANT
Open any email in Gmail, Outlook, or Yahoo Mail. Fred reads it automatically and shows a color-coded safety badge right in your inbox:
🟢 Safe — Verified sender, no threats found 🟡 Uncertain — Suspicious elements found, review before acting 🔴 Likely a Scam — Do not click links, download attachments, or reply
Click the badge for a full breakdown: risk score, detailed AI explanation, and every red flag Fred found.
HOW FRED ANALYZES YOUR EMAILS
Fred uses a two-stage AI pipeline that keeps safe emails fast and gives suspicious ones a deeper look:
AI triage — a fast AI model reads every email you open and flags anything that looks off
Deep AI analysis — flagged emails get a full threat assessment with a risk score and a detailed, plain-English explanation
The deep analysis only runs when triage flags something, so your inbox stays fast while real threats get explained.
