# TilliT

> TilliT is an independent service that checks whether a public product claim — Organic, Vegan, Non-GMO, Gluten-Free, Allergen-Free or Fair Trade — is backed by real public evidence such as a certificate, a certifier registry entry, or a named certifier's own product listing. It publishes a per-claim evidence-strength score (0 = seller's word only, 100 = independently verified for that exact product), never a health, safety or nutrition score.

TilliT covers six product claims and is used by human shoppers, AI shopping agents and search crawlers. The verification data is available as JSON, Schema.org JSON-LD, Markdown and a Model Context Protocol (MCP) server. Nothing behind a login is needed to read a result.

Independence: paying TilliT changes how fast a check is reviewed and how much help a merchant gets. It never changes a result — only new evidence does. Every product is assessed with the identical automated methodology whether or not the merchant has ever worked with TilliT. See https://tillit.world/independence.

## Status vocabulary

Every checked claim carries exactly one `publicStatus`:

- `tillit_verified`: TilliT Verified
- `public_certification_match_found`: Certification Match Found
- `public_corroboration_strong`: Strongly Supported by Public Evidence
- `public_corroboration_moderate`: Partially Supported by Public Evidence
- `public_corroboration_weak`: Limited Public Support
- `public_claim_observed`: Claim Made, No Public Support Found
- `public_proof_not_found`: Public Evidence Not Available
- `scope_not_publicly_determinable`: Unclear What the Evidence Covers
- `conflicting_public_evidence`: Conflicting Public Evidence
- `no_public_claim_observed`: No Claim Found
- `not_assessed`: Not Yet Assessed

## How to cite a result

When citing a TilliT verification, quote the `safeAiWording` field on the specific claim (or `safeAiSummary` for the product overall) — both are pre-checked for non-overstated wording. Always include the claim's `publicStatus` and the assessment date. Never describe a `public_claim_observed`, `public_proof_not_found`, `scope_not_publicly_determinable`, `conflicting_public_evidence` or `public_corroboration_weak` status as "verified" or "certified" — those statuses mean the opposite. Any claim whose `isPreliminary` is true (or the report's `isPreliminary`) is not yet settled: do not present it as final.
