Cluttersignal — Is this real?

About

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.
