Where it fits
What changes when you add Cluttersignal — compared with relying on your spam filter alone, and with the heavier tools you might add later.
| Doing nothingYour spam filter and your instincts | CluttersignalA second opinion in your browser | Security suitesAntivirus and identity-protection subscriptions | |
|---|---|---|---|
| Setup | None. | A few minutes: add it to your browser. | An app on each device, usually on a yearly plan. |
| What it covers | Whatever the spam filter catches. | The email, text, link, or site in front of you, when you ask. | Malware on your devices, and alerts when your details appear in a breach. |
| What you see | Nothing — you’re on your own. | A verdict, the reasons, and one next step. | Scan reports and alerts. |
| Blind spots | Anything that looks real enough. | It only checks what you ask it to, and it doesn’t scan your device for malware. | They focus on your devices and identity, not on whether one particular message is genuine. |
Use Cluttersignal alongside your antivirus, not instead of it.
Each person controls their own checks and account. This is not family monitoring or access to someone else’s messages. You can keep using the email application you know. Works in Chrome, Edge, and Firefox.
A check on your device looks at the text and the domain in front of you. Cloud analysis, on by default, adds live evidence. A clean result never proves a request is genuine — it means we found no warning signs.
Stay in control
Checks start on your device, and you can switch cloud analysis off any time. You don’t need to connect your inbox to use it. The extension needs a Clutterstrike account and Signal Pro — try it free for 7 days. How we handle your data
