False Claim Fingerprints

Continuous data about provably false narratives spreading online — built for false claim detection at scale.

NewsGuard’s global team of information reliability analysts maintains the internet’s most complete, continuously updated, machine-readable feed of data about false claims circulating online.

About our datastream: 

  • Early Warnings: NewsGuard detects and flags high-risk claims before any public reporting or fact-checks 73% of the time.
  • Global Coverage: Data covers false claims spreading across 102 countries worldwide in relevant local languages.
  • Malign Actor Monitoring: Claims sourced from monitoring of 35,000+ news and information sources and malign actors across platforms and the open web.
  • Precise Tracking: Data captures 42K+ instances of claims spreading with exact URLs, dates, excerpts, and relevant multimedia files.

Through a rigorous journalistic process, our analysts provide a definitive analysis of each claim with detailed evidence backing up any determination that a claim is false—along with human-verified URLs, keywords, search terms, social posts, multimedia assets, and language excerpts associated with the claim. 

The False Claim Fingerprints can be used:

  • By analysts tasked with defending against information operations from malign actors such as Russia, China, and Iran.
  • By AI tools to safeguard against false claims in responses or retrieval-augmented generation processes.
  • By technology platforms to safeguard against threats from foreign influence operations and other information threats.
  • By trust & safety teams to combat information threats, and track emerging narratives before they enter the mainstream.

Purpose-built for use by both human analysts and AI tools, NewsGuard’s False Claim Fingerprints provide a continuously updated view of the digital information environment — and a powerful way to track narratives that are emerging and spreading online before they spread widely.
