GuardScope is built for one job: helping Gmail users investigate suspicious emails before they act.
GuardScope works inside Gmail in Chrome and keeps the analysis focused on the email you choose to inspect.
The backend checks sender authentication, links, domain signals, threat feeds, and AI reasoning in one request.
You get a 0-100 risk score, plain-English reasoning, red and green flags, and suggested next steps.
Each scan combines AI, sender authentication, URL intelligence, and domain context into a plain-English report.
Mercury-2 reviews tone, urgency, impersonation cues, and social-engineering patterns.
Extracted links are checked against malware and phishing intelligence providers.
SPF, DKIM, DMARC, DNS, and domain signals help explain sender trust.
RDAP and lookalike checks help surface newly registered or suspicious domains.
The website, extension, and Chrome Web Store disclosures should tell the same story: GuardScope analyzes user-selected Gmail messages and does not keep email content.
Email content is processed only for the scan the user starts.
Email bodies, subjects, headers, sender details, and extracted URLs are not stored in GuardScope databases.
Account, quota, billing, promo, and abuse-prevention metadata may be retained where needed to operate the service.
Google API and Chrome extension user data use is limited to GuardScope email threat analysis.
Early users receive 30 days of Pro access while the Chrome Web Store launch is finalized. No credit card is required for the code.
We use this email only to deliver and support your promo code.
5 analyses per day per IP. No account required to start.
5 analyses per month per account with account-based history and settings.
30 days of Pro access for early users. Paid Pro is planned after launch.
No. Email content is processed for the scan you request and is not stored in GuardScope databases.
Anonymous users receive 5 analyses per day per IP. Signed-in free accounts include 5 analyses per month unless upgraded or using a promo code.
GuardScope needs access to Gmail pages so it can read the currently open email only when you ask it to analyze that message.
No security tool can detect every threat. GuardScope provides advisory analysis so you can make a more informed decision.
The first launch users can request a code for 30 days of Pro access. Codes are limited and can be revoked if abused.
Join the Chrome launch list and get GuardScope ready for suspicious Gmail messages.
