Worldwide Chat (WWC) by LastHopeLabs

Worldwide Chat (WWC) adds a live chat panel to every website you visit, with a built-in scam warning. Everyone with the extension on the same site sees the same room talk with people who are reading the same page, right now.

How it works

• Open the chat bubble in the corner of any page.
• Send a message, or set a nickname with /nick Name.
• One room per website: lasthopelabs.com has its own room, reddit.com has its own no mixing.
• Nothing to configure: while you browse, the bubble automatically checks the page and shows a small "risk %" label (with warning colors) when a page looks like a scam.

Automatic risk check (new in 0.3.1)

• On every page, only the site's hostname and page path are sent to our server. There, a tiny AI model (URLBERT) plus detection rules (brand typosquat, scam keywords, public-hosting traps) and WHOIS/RDAP data (domain age, registrar) score the page.
• The bubble shows "risque X%" from 25% and colors itself: red at 70%+, orange 45-69%, yellow 25-44%. Below 25% nothing is displayed legit sites stay clean.
• Whitelist = zero false positives: any page on a trusted domain (241+ major sites, incl. all Google country domains) always shows 0% risk.
• Pages confirmed as scams (public scam list) show 100% + a red SCAM badge, and the bubble moves to a visible position.
• The analyzer never blocks: if the model cannot load, the chat keeps working.

Features

• Instant live chat with everyone on the same site.
• Reviews tab: rate the site you are on (1-5 stars) and read what others think.
• Light and dark themes.
• Your identity is a random identifier (SID) stored in your browser: no account, no email, no password.
• A possession key keeps your identity safe: nobody can reuse your SID from another computer.
• Built-in anti-spam (rate limit per connection).

Privacy

• Only the hostname and page path of the page you are viewing are sent — to pick the right room and to run the scam check. No page content, no text, no forms, no history, no cookies.
• Messages you send are delivered to people on the same site and stored temporarily (last 1,000 messages per room).
• No ads, no trackers, no browsing history collection. Full policy: chat.lasthopelabs.com/privacy.html
