    Cautellus — The Internet’s Side-Eye
    
    Scan suspicious links, webpages, texts, and emails for scam warning signs before you click, reply, pay, or share information.
    
    Modern scams do not always look like scams.
    
    Fake Amazon emails look real. Package delivery texts sound believable. Marketplace buyers and sellers seem normal. Job offers look professional. Romance profiles use convincing photos. Fake invoices, payment screenshots, checks, and “urgent account warnings” can fool even smart people.
    
    Cautellus gives you a fast scam-risk check in plain English — right from your browser.
    
    Before you click the link, trust the message, send the money, or hand over personal information, Cautellus helps you pause and check for red flags.
    
    Get a Clear Scam Risk Result
    
    Cautellus gives you an easy-to-understand result:
    
    ✅ SAFE
    ⚠️ SUSPICIOUS
    🚨 SCAM DETECTED
    
    You also get a simple explanation of what looks risky, so you are not left guessing.
    
    What Cautellus Does
    
    Cautellus adds an extra layer of scam protection while you browse.
    
    You can:
    
    ▸ Click “Scan This Page” to check the website you are viewing
    ▸ Right-click a link and choose “Check this link for scams”
    ▸ Highlight suspicious text and scan it instantly

    When to Use Cautellus
    
    Use Cautellus anytime something online feels a little off.
    
    Examples include:
    
    ✓ A text says your package is stuck at customs
    ✓ A fake “Amazon order” email asks you to click
    ✓ A Marketplace seller wants payment outside the platform
    ✓ A recruiter offers easy money for a vague job
    ✓ A customer sends a suspicious invoice or payment screenshot
    ✓ A family member asks, “Is this Microsoft warning real?”
    ✓ A dating profile feels too perfect
    ✓ A link, message, website, or offer gives you that uneasy feeling

    Who Cautellus Helps Protect
    
    Cautellus can help:
    
    ✓ Online shoppers
    ✓ Parents and elderly relatives
    ✓ Small business owners
    ✓ Customer service teams
    ✓ Job seekers
    ✓ Marketplace buyers and sellers
    ✓ Online dating users
    ✓ Anyone who receives suspicious links, messages, screenshots, or offers
    
    For small businesses, Cautellus works like a quick safety check before opening unfamiliar links, responding to questionable messages, or trusting unknown websites.
    
    Why Cautellus Is Different
    
    Many browser tools only check whether a website is already known to be dangerous.
    
    Cautellus looks deeper.
    
    It reviews the actual content you choose to scan, including page text, links, visible information, and scam-pattern signals. Then it explains the warning signs in a way normal humans can understand.
    
    Cautellus can help detect:
    
    ✓ Brand impersonation
    ✓ Fake delivery notices
    ✓ Suspicious payment requests
    ✓ Marketplace scam behavior
    ✓ Romance scam warning signs
    ✓ Job scam patterns
    ✓ Sketchy links and domains
    ✓ AI-generated scam language
    ✓ Urgency, pressure, and manipulation tactics
    
    Because sometimes the scam is not the website.
    
    Sometimes it is the message.
    The fake invoice.
    The too-perfect offer.
    The “just send the deposit” moment.
    
    That is where Cautellus steps in.

    DON'T GET SCAMMED.
    
    ScamSecurityCheck gives you a 3-second sanity check before you click, reply, send money, or hand over information. Get back SAFE / SUSPICIOUS / SCAM DETECTED — with exactly WHY, in plain English.
    
    Modern scams don't look like scams anymore. AI-generated phishing emails are pixel-perfect. Fake "Amazon" texts mimic the real thing. Job recruiters have real LinkedIn profiles. Romance matches have real-looking photos. The bad guys got better. This extension helps you catch up.
    
    ══════════════════════════
    
    WHAT IT DOES
    ══════════════════════════
    
    
    ▸ Click "Scan This Page" to instantly check any site you're on
    ▸ Right-click any link → "Check this link for scams"
    ▸ Right-click selected text → "Check selected text for scams"
    ▸ See a 0–100 risk score plus the specific reasons it scored that way
    ▸ If a recent FBI alert matches what you scanned, you'll see it linked directly in the result
    
    ══════════════════════════
    
    WHEN YOU'LL USE IT
    ══════════════════════════
    
    
    - That "your package is held at customs" text → right-click the link, scan it
    - A LinkedIn recruiter offering $200/hr for 5 hrs/week → scan their page
    - An "Amazon order confirmation" you don't remember placing → scan the page
    - A Facebook Marketplace seller with a too-good price → scan the listing
    - Your mom asking "is this Microsoft alert real?" → scan it for her in 3 seconds
    - Anything that gives you that gut feeling something's off
    
    ══════════════════════════
    
    WHY IT'S DIFFERENT
    ══════════════════════════
    
    Most "phishing checkers" only look at the URL. ScamSecurityCheck cross-references multiple layers of intelligence on every scan:
    
    ✓ Brand impersonation patterns (chase-secure-verify.top fools nobody once you see it)
    ✓ Sketchy top-level domains (.top, .buzz, .click — the same crew uses them all)
    ✓ Active scam databases from Reddit's scam-victim communities
    ✓ Recent FBI Internet Crime Complaint Center alerts
    ✓ FTC consumer fraud bulletins
    ✓ AARP fraud watch reports
    ✓ AI risk analysis for urgency, money asks, and fake authority
    
    ══════════════════════════
    
    WHO IT'S FOR
    ══════════════════════════
    
    
    - Anyone who's ever frozen with a sketchy text in their hand
    - Adult children worried about elderly parents getting targeted
    - Online dating users who want to vet a profile before they trust
    - Job seekers verifying recruiters before sharing a resume
    - Online shoppers checking sellers before they pay
    - Small business owners protecting their team from BEC scams

    ✓ A dating profile feels too perfect
    ✓ A link, message, website, or offer gives you that uneasy feeling
    
    Before you click. Before you pay. Before you reply. Scan it with Cautellus.
    
    It can help protect:
    
    ✓ Online shoppers
    ✓ Parents and elderly relatives
    ✓ Small business owners
    ✓ Customer service teams
    ✓ Job seekers
    ✓ Marketplace buyers and sellers
    ✓ Online dating users

    Why Cautellus Is Different
    
    Many browser tools focus only on known bad websites.
    
    Cautellus looks deeper.
    It reviews the actual content of the page you are looking at — including links, page text, and visible information — then explains what looks risky.
    
    Cautellus can help detect:
    
    ✓ Brand impersonation
    ✓ Fake delivery notices
    ✓ Suspicious payment requests
    ✓ Scammy marketplace behavior
    ✓ Romance scam warning signs
    ✓ Job scam patterns
    ✓ Sketchy links and domains
    ✓ AI-generated scam language
    ✓ Urgency, pressure, and manipulation tactics

About

Cautellus — The Internet’s Side-Eye

Cautellus helps you check suspicious websites, links, and page text before you click, pay, reply, or trust what you’re seeing online.

Modern scams do not always look like scams. Fake delivery texts, Amazon emails, Marketplace buyers, job offers, payment screenshots, invoices, and urgent account warnings can all look believable.

Cautellus gives you a fast scam-risk result right from your browser — in plain English, not cybersecurity nonsense.

What You Can Do

▸ Scan the webpage you’re viewing
▸ Right-click a suspicious link and check it
▸ Highlight suspicious text and scan it
▸ Use Cmd+Shift+S or Ctrl+Shift+S for a quick scan
▸ Get a 0–100 scam risk score
▸ See warning signs explained clearly
