AI Vendor Data-Trust Index live

A transparent, source-cited comparison of how AI products handle your data — does the vendor train on it, is zero data retention available, can you opt out. Every value carries the exact policy quote, source URL, and date it was checked.

Source-cited & verified

Every value is checked against the vendor's live policy and carries a verbatim quote, source URL, and date. Ambiguous cases are marked unclear rather than guessed. An automated verifier re-checks weekly; changes are logged. Spotted an error? Send a correction →

What this answers

One plain question with a cited answer: if I send my data to this AI product, what happens to it? The headline fields are whether the vendor uses your inputs to train its models, whether a zero-data-retention option exists, and whether you can opt out. "Unclear" is used deliberately — a missing or ambiguous policy is never rounded up to a favorable answer.

How each value is established

Each field is extracted from the vendor's published policy and stored with the exact supporting quote, the source URL, a confidence level, and the date it was checked. A value changes only when the source text changes, and every change is dated. Nothing is inferred beyond what the policy states. An automated verifier re-checks the sources weekly: it only publishes a definite value when a verbatim quote from the live policy supports it, and holds the current human-verified value otherwise. Ambiguous or unconfirmable fields are marked unclear, never guessed.

How an AI agent can use it

Every response is source-cited with the quote and URL behind each value:
