Double Check vs ScamAdviser — honest comparison
What each does
ScamAdviser is a website trust-rating service. You paste in a URL — ScamAdviser returns a 0-100 trust score based on domain age, hosting location, SSL certificate, traffic patterns, and crowdsourced reviews. It's been around since 2012 and has rated tens of millions of sites.
Double Check reads the actual content of suspicious messages — text, email, screenshot — and tells you whether the message is a scam, what kind, and what to do. URL analysis is part of what it does, but it's not the whole product.
What ScamAdviser is good at
Quick risk-rating of a specific website you're about to buy from or hand details to.
Useful for shopping decisions — 'is this Black Friday deal site legit?'
Free for casual use; paid API for businesses.
Browser extension that warns you as you browse.
Where ScamAdviser falls short
Only useful if you already have a URL — most scams don't start with a website, they start with a message.
Cannot evaluate text-message scams, email scams, or screenshot-based scams.
Trust scores can be misleading for brand-new legitimate sites (low score because the domain is young) and for sophisticated scams (high score because the scammer set things up properly).
Doesn't tell you what to do — just gives a number.
What Double Check is good at
Reading any suspicious message and explaining in plain English whether it's a scam.
Handles text, email, screenshots, and URLs all in one place.
Returns a verdict with reasoning and a 'what to do next' answer — not just a score.
Built for non-technical users (older adults, in particular).
Family-alert feature so an adult child gets notified about suspicious messages received by a parent.
Where Double Check falls short
For 'is this random shopping site legit?' style queries, ScamAdviser's specialized rating is more focused.
No browser extension yet — ScamAdviser has this.
Which should you use?
'I'm about to enter my card on this website I've never used — is it real?' → ScamAdviser.
'I got this weird text / email / DM — is it a scam?' → Double Check.
'My elderly parent keeps getting suspicious messages — how do I protect them?' → Double Check, with family alerts on.
'I'm doing a quick safety check on a delivery-tracking page someone texted me' → either works, but Double Check also reads the message that delivered the link.
The realistic stack: bookmark ScamAdviser for one-off site checks. Install Double Check (or have a parent install it) for the continuous flow of suspicious messages that arrive every week.
