Airport51 Inc · Origin of Pieces
Trace where digital content first appeared and how it evolved.
Free. No account required. Evidence, not a truth verdict.
Searches public archives for the earliest known appearance and independent crawl witnesses. Language: earliest known public witness — never “original source found.”
Text-only analysis can locate matching occurrences and stylistic signals. It cannot declare a definitive origin URL. Language: earliest matching occurrence located — never “original source found.”
File-level provenance (hash, metadata, embedded credentials) is coming soon. Upload analysis is not available in this free Origin Check yet.
Image provenance (online occurrences, Content Credentials / C2PA when present) is coming soon. Absence of credentials is not proof of synthesis.
— a real 2014 essay with inspectable witnesses.
The pipeline
Evidence before scores. Archive and crawl witnesses first; model-derived signals only as secondary context. No single signal decides the reading.
Live lookups against the Internet Archive and Common Crawl for the earliest known public appearance and independent corroboration. Earliest known is not original creation.
An evidence timeline and witness ledger show each observation with timestamp kind, independence, and limitations — inspectable, not a black-box score.
Every report states what was observed, inferred, conflicted, and not established. Provenance is not truth; public existence is not authorship proof.
Publication-era priors and stylistic heuristics appear only after the evidence trail, labeled contextual and weak — never as proof of authorship.

The Human-Origin Prior Curve
The truth boundary. Darwin establishes existence, observed time, and integrity evidence. Whether a work’s claims are factually true sits outside that boundary.
The piece appeared somewhere public, and Darwin can point to where it was observed.
When it appeared or was captured, corroborated across independent witnesses rather than a single source.
Whether the observed record has stayed consistent across the capture span since it was first sighted.
Whether the work’s claims are factually correct. A page can exist, be old, and be unchanged, and still be wrong. Darwin does not rule on this.
The full report
Every voyage kept a log. The Beagle Log is Darwin’s full, dated, reproducible record of a work’s origin, and of everything that has drifted toward it since.

Methodology note
Origin of Pieces verifies provenance, not absolute truth. It shows what was observed, when it was observed, where it was observed, and how strongly independent witnesses support the evidence chain. The free Origin Check is a preliminary reading based on visible timestamp and provenance signals plus on-device text heuristics. It is not a statement that content is “human-made” and not a legal conclusion.
Darwin never treats a single archive result as final. A finding is presented as corroborated by N independent witnesses, and one witness alone is flagged as not independently corroborated. AI-detection heuristics are weak witnesses only. Scores are reproducible computations, presented as evidence strength rather than authority. Input modes are not evidentially equal: URL, text, file, and image analysis carry different claims and confidence ceilings.
Darwin is an evidence-analysis instrument, not legal advice. Where data was not publicly retrievable it is reported as not established, never silently inferred.
