Cluttersignal — Is this real?

Cluttersignal checks any email, text, link, or website for phishing and scams, so you know what to trust before you act.

Is this real? Cluttersignal tells you in a second. Phishing emails, fake invoices, and scam links are built to look legitimate. Cluttersignal checks any email, text message, link, or website for the signs of deception — brand impersonation, look-alike (typosquat) domains, credential and payment traps, manufactured urgency, and more — and gives you a clear verdict before you click, reply, pay, or type a password. WHAT YOU GET • Automatic safety badge — as you browse, Cluttersignal shows an on-device safety badge for the site you're on. No account needed, and nothing about the pages you simply visit is sent anywhere. • Check anything on demand — open the popup or the side panel to scan the email you're reading, paste in a suspicious message, or check a link. You get a clear safe / caution / suspicious / dangerous verdict with the reasons behind it. • Side panel — prefer it always open? Switch to a docked panel that stays visible while you read. PRIVATE BY DESIGN • The on-device badge transmits nothing — it reads the page locally in your browser. • Content you explicitly ask us to check is analyzed to produce your verdict, then discarded — never stored, never sold, never used to train AI models. • A link check sends only the bare domain, never the full address. FREE, WITH AN OPTIONAL UPGRADE • The verdict is free. Connect a free Clutterstrike account to run on-demand checks. • Signal Pro adds the full report: a plain-English explanation, the domain's registration age, and whether you've dealt with that sender or domain before. It's included with every paid Clutterstrike Workspace plan, or $8/month on its own. Cluttersignal is a best-effort signal, not a guarantee. Automated checks can miss threats or misjudge safe content — always use your own judgment before acting.
