Stack-check protocol · AI vendor lookupBeta

Grade any software vendor against the six questions.

Beta. This lookup only reads each vendor’s own public TOS, MSA, DPA, trust center, and privacy pages. Validate every answer with the software provider before you sign anything.

Reads the vendor’s current terms and grades their answers to the six questions below. Rate-limited to 5 fresh lookups per hour.

Searching the vendor’s documents… this usually takes 15–30 seconds.
