A scam & phishing checker for Gmail
ScamChk puts a coloured dot on the emails in whatever Gmail view you’re looking at: your inbox, or any label. Red means a likely scam or phishing attempt. You see it before you click, not after.
Scam or phishing, with hard evidence: a forged sender, a link that hides where it goes, an address Google lists as dangerous.
Something doesn’t add up. ScamChk says what, and what to do before you click.
Promotional mail with no signs of a scam. Unsubscribe if you know the sender.
Never “safe”: a second opinion, not a guarantee. We say exactly that.
Open an email and the colour sits next to the subject. Click it: what we found, in one sentence each, and what to do next. No jargon, no scare tactics.
Is the sender who it claims to be? Do the links go where they say? Does Google list them as dangerous? Most emails are decided here.
When the facts can’t decide, an AI model reads the email for pressure, fake logins, payment lures and impersonation.
Scam, phishing, or just marketing: one colour, the reasons, and what to do next.
A scam is any email that tries to trick you out of money or something valuable: a fake invoice, a prize you never entered, a “too good to be true” investment, a stranger who needs help.
Phishing is a kind of scam that pretends to be someone you trust (your bank, a delivery service, your email provider) to get your password, card details or other personal data, usually through a link to a fake sign-in page.
ScamChk checks for both. A red dot means either.
Spam is unwanted bulk mail: annoying, usually harmless. Gmail’s filter already catches most of it. ScamChk looks at what made it into your inbox. Legitimate promotions get the blue Marketing dot.
No. Auto-check is off by default, and you decide which emails to check: the one you open, the ones you select, or the page you’re looking at. ScamChk reads only the emails it checks.
With Auto-check on, it checks the page of emails you’re looking at, in your inbox or any label. Never your whole mailbox in the background. An email keeps its colour once it’s checked, so it isn’t checked over and over.
No. The checking runs on our servers, not on your computer. ScamChk only adds the dots and the panel to Gmail. A check takes a few seconds, and you can keep reading and working while it runs.
Gmail, in Chrome on a computer. You sign in with your Google account.
Nothing during the limited beta. We’re still working out the prices for after that. Plans will start under $3 a month, with an introductory price for early users.
We email you at least 14 days before, with the price and the date. Choose a plan and ScamChk keeps working. If you don’t, it stops checking when the beta ends. The beta needs no card, so nothing is ever charged unless you choose a plan.
Yes. It’s a second opinion, not a guarantee, which is why green says “No red flags found” and never “safe”. When in doubt, go to the company’s site or app yourself instead of using the email’s links.
Make sure it gets a red dot before you click anything in it. ScamChk is free in a limited beta. Spots go first come, first served. Leave your email and we’ll tell you the moment new spots open.
