Questions before you paste
Clear limits make a better quality gate.
What does “unsupported” mean?+
The supplied source does not justify treating the draft statement as agreed scope. It does not prove the statement is false in the real world.
Does my text leave the browser?+
This browser pre-check runs on your device. It does not send the pasted source or draft to Discovery QA.
Is the browser checker the same as the full kit?+
No. This page uses a lightweight text-matching heuristic. The full kit provides a structured, AI-assisted audit across omissions, contradictions, roles, business rules and readiness.
Can I paste confidential material?+
Only use material you are authorized to process. Remove secrets and unnecessary personal data even when a tool runs locally.
How we measure use
We count page loads, checker runs and selected link clicks by day and broad campaign source. These counters do not contain your pasted text, findings, email, IP address or visitor identifier. They use no analytics cookies or browser storage and respect Do Not Track and Global Privacy Control. Our hosting provider processes technical requests to deliver the site. Gumroad has its own privacy practices when you follow a product link.
When the pre-check is not enough
Audit what the draft invented — and what it quietly left out.
The complete Discovery QA Kit adds missed evidence, source contradictions, roles and permissions, business rules, testability, open decisions, traceability and an estimation-readiness score.
