Fact-checking infrastructure for publishers
Build trust into every story.
Bring source-linked fact-checking into your product with the API, add a Fact-vs-Opinion bar to WordPress, or check claims directly in Chrome.
Three ways to get started
Choose how you fact-check.
Integrate with your app, publish on WordPress, or verify what you read in your browser.
