What it checks
Six ways to check before you act
Paste it, upload it, or type it in — Scam Checker looks for the signals scammers rely on and explains every verdict in plain English.
Links & websites
URLs are checked against Google Safe Browsing and domain-registration signals, so a blocklist hit, a clean result, and an unavailable check are never confused.
Emails & texts
Paste an email, SMS, or WhatsApp message. Urgency language, payment-change asks, gift-card requests, and credential traps are flagged and explained.
Screenshots & documents
Upload an image, PDF, or Word file. It is scanned in your browser for embedded links, QR codes, bank details, and crypto wallets — the file itself is never uploaded.
QR codes (quishing)
QR codes found in images and PDFs are decoded and their destination run through the same URL checks — the fastest-growing scam delivery trick.
IP addresses
Any public IP — including ones found inside a message — is checked against AbuseIPDB's abuse-report database.
Community reports
Every result shows matching scam reports from other users, with counts and recency, and you can add your own to warn the next person.
Privacy
Checked in your browser, not on our servers
A scam checker only deserves trust if it treats your data the way we tell clients to treat theirs.
Files and screenshots are analysed in your browser — they are not uploaded or stored.
Pasted content is not kept as scan history; only extracted indicators (links, numbers) are checked server-side.
Free to use with no account and no sign-up.

FAQ
Scam Checker questions
Is Scam Checker really free?
Yes. The web tool is free to use with no sign-up. It exists because scam triage should be available to everyone, not just businesses that can pay for a consultant.
Does it upload my files or messages?
No. Images, PDFs, and documents are scanned inside your browser and never uploaded. Pasted messages are not kept as scan history — only extracted indicators such as links, phone numbers, and IP addresses are checked against reputation services.
Can it guarantee something is safe?
No tool honestly can. A 'lower risk' verdict means no known red flags were found — it is not a guarantee. For payments, always verify account details with the other business using a phone number you already trust.
Got a suspicious message sitting in your inbox right now?
Check it in seconds — free, no sign-up, nothing stored. And if your business handles invoices and payments, Sam can put protections behind the whole team.
