What it is
The Global Trust Index is GriGsi’s core: people vote Trust or Warn on domains, URLs, emails, phone numbers, IBANs, or any text. Votes are aggregated into a simple trust score and tier. The layer is hash-first; we minimise PII (Personally Identifiable Information) — see the Privacy Policy for servers, telemetry, and exceptions. The more people contribute, the more useful the index becomes for everyone.
Tiers
The server assigns a tier from votes and signals (e.g. number of unique voters, positive ratio, time span, countries):
- Observation New or not enough data; low vote count or spread.
- Soft trust Enough positive votes and diversity (e.g. many voters, high positive ratio, time span).
- Confirmed Strong consensus: many voters, high positive ratio, longer span, often multiple countries.
- Flagged Suspicious activity (e.g. velocity, abuse). Shown so you can be cautious.
How to use it
Extension
Install the GriGsi extension (Chrome, Edge, Opera, Firefox, Safari). You see trust for the current tab and can check any domain, email, or link in the popup. Vote Trust / Warn with one click. Free; optional licence removes ads and unlocks unlimited Info Noise Index.
Website
On the Check Index page enter a domain, URL, or email and click Check. Results show tier, votes, and trust %. You can vote from the result.
API
For your site or app: GET /trust?hash=... or GET /api/trust/batch. Free tier has limits; paid plans for higher volume. See API & embed.
Trust badge
Embed a small widget on your site to show your domain’s trust score. Embed snippet.
Extension: GriGsi Sentinel (when the trust panel appears)
The browser extension can show an in-page GriGsi Sentinel panel when you open a site so you can confirm or continue. That flow is about browsing safety and interruption — it is not the same as the Global Trust Index score itself, and it is not the same as Info Noise Index → “My trusted sites”. The Info Noise Index setting only splits sources inside Info Noise Index; it does not control Sentinel.
First install only
Right after install (or if you resume first-run setup from the popup), the tab may open with ?welcome=1: a ~5 second Sentinel preview (skippable) runs first, then the same tab shows Sentinel on the left and Community / Private choice on the right until you decide. Opening setup later from Options to change mode does not run this flow again.
Quiet / exception domains
The extension ships with a curated list of about 300 hostnames (large platforms, payments, retail banks, government and health portals, common tools, and similar high-traffic sites). For those hosts — including typical subdomains (e.g. mail.google.com when google.com is listed) — Sentinel does not open automatically, so everyday browsing is not stopped on every navigation.
Other sites
If a site is not on that exception list, Sentinel will appear. That is expected behaviour, not a bug.
Why it can feel “sometimes yes, sometimes no”
The extension also fetches a server-published list (e.g. GET /trusted-domains on the GriGsi server). When that succeeds with a non-empty list, it replaces the built-in list until the next refresh. So the same hostname can follow built-in rules at one moment and server rules after an update — it is not random; it reflects which list is active.
This page (Check Index on the web)
Typing a domain here only queries trust for what you enter. It does not use the Sentinel / exception-list navigation flow.
FAQ
Yes. Personal use (extension + website check) is free. Contextual ads may show in the extension; a Pro licence removes them. Organisations pay for Spaces; developers/companies pay for API and embedding.
Anyone using the extension or the website. Votes are tied to an anonymous client id (no email, no account). Rate limits apply to prevent abuse.
The value you check (e.g. domain, email) is hashed (SHA-256) before being sent. Only the hash and vote counts are stored; we never store the raw value.
Yes. In a paid Space you can use shared trusted domains and your own fact-checking (Info Noise Index) with your chosen sources. See Spaces and Plans.
That is GriGsi Sentinel. It uses a built-in exception list (and sometimes a server-updated list) so widely used sites stay quiet while other sites still get a prompt. This is separate from Info Noise Index → My trusted sites. Details: Extension: GriGsi Sentinel above.
