NarrativeCheck
A fact-checking workspace for journalists and content moderators that automatically flags when a video contradicts its own narration — e.g., a caption claiming "we never visited the site" while footage clearly shows the visit.
Investigative journalists, political fact-checkers, and social media content moderation teams
- Upload a video plus its transcript/captions and receive a side-by-side timeline flagging every claim the visuals contradict
- Confidence score per flagged mismatch with the exact visual excerpt supporting or undermining the claim
- One-click export to a standard editorial fact-check brief with citations
- Moderation API for social platforms to auto-flag misleading political uploads at ingestion time
