WHAT YOU GET
A DEFENSIBLE ANSWER — OR AN HONEST UNKNOWN.
- YOU BRING THE QUESTION
A claim, link, file, or transaction hash. Intent matters: the same video can be an origin question or a publish question.
- REQUIREMENTS
The question is decomposed into evidence tasks: original, place, date, independence, contradiction, unknowns.
- EVALUATION
SUPPORTED, CONTRADICTED, INSUFFICIENT EVIDENCE, or HUMAN REVIEW. No 98% true.
- THE REPORT
What is established, supported, contradicted, and unknown — plus what would change the finding.
DEMONSTRATION REPORTS
PUBLIC CASES. LABELLED. NOT CUSTOMER STORIES.
Compiled from cited public records. Findings are not invented. If the evidence is thin, the state is INSUFFICIENT EVIDENCE.
DEMO-HASINA-PHOTO
CONTRADICTEDDoes the circulating photograph show Sheikh Hasina at the 5 August 2026 New Delhi press-club appearance?
CONTRADICTED as a photograph of the 5 August 2026 New Delhi appearance. AFP Fact Check (20 August 2026) reports a reverse-image match to a 20 December 2022 Awami League post from Dhaka. Duplios compiled that public record; it did not independently retrieve the 2022 file.
OPEN DEMONSTRATIONDEMO-DHARALI-NEPAL
CONTRADICTEDDoes the circulating flood image show the August 2026 glacial floods at the Nepal–Tibet border?
CONTRADICTED as imagery of the August 2026 Nepal–Tibet floods. AFP Fact Check (2026) traces the still to a 5 August 2025 AccuWeather post of Dharali, India, credited to Reuters Connect.
OPEN DEMONSTRATIONDEMO-YAMAL-AI
CONTRADICTEDAre the circulating images photographs of Lamine Yamal holding a keffiyeh at the 2026 FIFA World Cup final?
CONTRADICTED as photographs of that scene. AFP reports reverse-image matches to Associated Press photographs of a different moment and states OpenAI/Google SynthID and Hive tools flagged the keffiyeh composites. Detector scores are indicators only; they are not a Duplios authenticity verdict.
OPEN DEMONSTRATIONDEMO-C2PA-AUTHENTIC
CONTRADICTEDDoes C2PA prove that a media file is authentic — that the depicted event happened as shown?
CONTRADICTED. C2PA is a provenance-credential system. The 2026 IACR analysis states C2PA was not designed to determine authenticity and that versions 2.2–2.4 fail claimed and essential security goals. Absence of C2PA is not evidence a file is fake.
OPEN DEMONSTRATIONMETHOD
EVIDENCE, NOT OPINIONS.
One hundred copies of the same article derived from one wire are one independence group, not one hundred confirmations. Missing EXIF is not fakery. Missing C2PA is not fakery. An AI detector score is not truth. A blockchain transaction is not a real-world identity.
