PromiseDiff

PromiseDiff is a QA tool that compares digital product listings, such as claims about page counts or content types, against the actual PDF or ZIP files delivered to buyers. It validates facts directly, checks semantic content with AI assistance, and categorizes claims as supported, contradicted, or unverified, helping creators avoid mismatches that cause refunds and disputes. The tool runs locally with size and security limitations and emphasizes transparency by attaching evidence to every conclusion.
