Darwin : Digital Origin of Pieces Can a piece’s human origin still be proven? Has AI content diluted it? Paste URL or text → Human-Origin Snapshot in your browser. Cross-checks independent sources (Internet Archive, HN, Wikipedia, Crossref, OpenAlex, GDELT) for first appearance and witnesses. Certifies only: Existence • Timestamp • Integrity (Not truth - just provenance.) Free. Still evolving. Suggestions welcome. Cheers Bastiaan
