slop-up is the consent-first data marketplace for discarded AI artifacts. Secondary value layer for slop-zone — when users are ready to delete old AI outputs, brainstorms, specs, drafts, images, notes, or datasets, they can choose to redact, license, donate, sell, or privately share those artifacts for AI research, model testing, training, benchmarking, and creative reuse. Every package starts private. Must pass privacy review, rights attestation, license selection, and explicit publish approval before becoming a marketplace listing. Licenses: free, paid, request-access, research-only, private-invite. Current snapshot: 18 draft packages, 7 review warnings, 42 published sets, 126 research buyers.
