About IsThisSpam - Scam & Spam Detector
Check suspicious emails, links, and websites before you act.
IsThisSpam is a browser protection extension that helps you spot phishing, scams, spam, impersonation, and other risk signals - then explains what it found in plain language.
EMAIL PROTECTION
• Check messages in Gmail, Outlook, and Yahoo.
• Analyze an opened message automatically or run a deliberate check.
• Look for phishing, fake invoices, impersonation, suspicious senders, urgent requests, deceptive wording, risky links, and unusual attachments.
LINK AND TEXT CHECKS
• Right-click a link to check it without opening it.
• Select suspicious message text and send it for analysis.
• Check supported social and profile links when you need a second opinion.
BROWSING PROTECTION
• Turn on optional browsing protection to check website addresses as pages load.
• Get an on-page warning when a website matches configured risk settings.
• Use the floating check button to run a manual page check while you browse.
• Manage trusted sites and browsing access from the Protection Center.
CLEAR RESULTS
• See risk categories, supporting signals, explanations, and practical next steps.
• Review recent email and website checks in the Protection Center.
• Keep check history stored locally in your Chrome profile.
FREE TO START
• Begin with no account required.
• Get 10 combined email and website checks per local day.
• After the allowance is used, anonymous users can create an account or sign in to continue; free accounts can upgrade for unlimited protection.
• Eligible Personal, Business, Apple-linked, and StackSocial access can unlock premium extension protection.
PRIVACY AND CONTROL
• Inbox checks work separately from optional all-site browsing access.
• Website access is requested only when you enable browsing protection.
• Choose IsThisSpam Servers, supported cloud providers, or local Ollama/LM Studio providers in Settings.
• Checked content is sent only to the provider you select when a check runs. Local providers process content through the local server you configure.
Automated results are advisory, not guarantees. Always verify unexpected requests through a trusted contact before sharing credentials, sending money, or opening an attachment.
