About
Fact Check Explorer is a free, web-based search tool by Google that aggregates published fact-checks from credentialed third-party fact-checking organizations worldwide. Users can search by keyword, claim, or public figure to instantly surface relevant verdicts — including ratings like 'True,' 'False,' or 'Misleading' — sourced from publishers like PolitiFact, Snopes, AFP Fact Check, and hundreds of others across many languages and regions. The tool is built on the ClaimReview structured data schema (Schema.org), which publishers use to mark up their fact-check articles. Google's crawlers ingest this data and make it queryable through the Explorer interface and the companion Fact Check Tools API, which allows developers to programmatically access the same database via REST calls using a Google API key. Fact Check Explorer is aimed at journalists, researchers, fact-checkers, and educators who need to quickly verify whether a claim has already been reviewed. Results display the original claim, the claimant, the verdict, the reviewing organization, the publication date, and a direct link to the full fact-check article. The API and web interface are both provided free of charge as a public-interest resource.
Key Features
- Global Claim Search: Search a continuously updated database of fact-checks by keyword, topic, or public figure, surfacing verdicts from hundreds of credentialed fact-checking organizations worldwide.
- ClaimReview Schema Integration: Built on the open ClaimReview structured data standard, allowing publishers to contribute their fact-checks and ensuring results include structured verdicts, claimant info, and ratings.
- Publisher & Language Filtering: Filter results by specific fact-checking organizations or browse across dozens of languages and regions, reflecting a truly international network of fact-checkers.
- Fact Check Tools API: A free REST API (requiring a Google Cloud API key) gives developers programmatic access to the same claim database, returning structured JSON with claim text, rating, publisher, and URLs.
- Google Search & News Integration: Fact-checks indexed via ClaimReview also surface as rich result labels in Google Search and Google News, extending their reach beyond the Explorer itself.
Pros
- Completely Free: Both the web interface and the Fact Check Tools API are available at no cost, making it accessible to individuals, newsrooms, and developers alike.
- Broad International Coverage: Aggregates fact-checks from hundreds of organizations across many countries and languages, providing a genuinely global perspective on verified claims.
- Structured, Machine-Readable Data: Results are based on the standardized ClaimReview schema, making data consistent, well-organized, and easy to consume programmatically via the API.
- No Account Required for Basic Use: The web Explorer can be used immediately without signing in or creating an account, lowering the barrier to entry for casual users.
Cons
- Dependent on Publisher Participation: Coverage is limited to claims that have been fact-checked and marked up with ClaimReview by participating publishers; unreviewed misinformation will not appear in results.
- No Native Mobile App: There is no dedicated iOS or Android application; mobile users must rely on the browser-based interface, which lacks a tailored mobile experience.
- Quality Varies by Publisher: The tool aggregates from a wide range of organizations, and the rigor, methodology, and credibility of individual fact-checkers can vary significantly.
