AI assistant that reads your emails and explains suspicious messages in plain English. Is this email a scam? Fred is an AI-powered email safety assistant that reads every message in your inbox and explains what it found in plain English — so you always know whether an email is safe or suspicious.
Stop wondering "is this email legitimate?" — Fred explains it for you.
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.
FRED EXPLAINS EVERY EMAIL — NOT JUST THE SUSPICIOUS ONES
Not sure what an email is or why you got it? Fred tells you in one plain sentence: "This is an advertisement. Kohl's is trying to sell you something." "This is a bill or payment notice. It's asking you to pay." "This is a bank or financial notice. It's just letting you know something — there's nothing to buy or sign." Fred also spots sponsored content, tells you whether anything needs doing, and explains confusing words like "EOB" or "ACH transfer." If an email is pretending to be your bank, Fred says exactly that.
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.
