What Comprova does

Comprova (legal name: Projeto Comprova) is a non-partisan, non-profit collaborative fact-checking initiative founded in 2018 and coordinated by Abraji (Associação Brasileira de Jornalismo Investigativo), headquartered in São Paulo, Brazil. The project brings together journalists from 42 Brazilian media organizations, including AFP, Folha de S.Paulo, Estadão, UOL, SBT, and Correio Braziliense, to investigate and verify suspicious content circulating on social media and messaging apps in domains such as politics, public health, climate change, elections, and virtual scams. Each verification is produced by three reporters from different organizations and undergoes peer review requiring consensus from at least three non-participating journalists before publication, a process the project calls cross-checking. Since inception, 425 journalists have participated through eight phases of investigations.

The product portfolio consists of collaborative fact-checking reports (Verificações de Fatos), explanatory articles (Comprova Explica), virtual scams investigations (Golpes Virtuais), contextualization pieces (Contextualizando), and step-by-step guides (Passo a Passo), plus media literacy courses and an AI guide for journalists. The platform integrates third-party AI detection tools (Hive Moderation, Hiya/Invid) for deepfake and synthetic audio identification, Google NotebookLM for educational content, and Copernicus satellite imagery for environmental verification. Distribution occurs through a dedicated website, a mobile application, and social media channels including a WhatsApp channel launched in 2025.

Comprova operates as a free public service with no commercial revenue. The initiative is funded by institutional grants from Google News Initiative and Meta Journalism Project, with methodological support from First Draft. The core customer segment is Brazilian citizens exposed to disinformation on social media and messaging platforms; the user base grew 260% in new users and 116% in page views between June and October 2025 following the adoption of a new empathetic verification approach.

Broad incumbents

• Full Fact: UK-based fact-checking charity founded in 2009 with AI-assisted verification tools and government-policy misinformation focus. Comparable as a non-profit peer fact-checker with similar technology-augmented methodology and cross-checking workflows to Comprova.
• PolitiFact: U.S.-based Pulitzer Prize-winning fact-checking organization and IFCN signatory that pioneered the Truth-O-Meter rating methodology. Comparable as a peer fact-checker in a different market with similar political-disinformation focus, though operates as a single newsroom rather than a coalition.
• Snopes: Pioneer U.S.-based fact-checking website founded in 1994 covering misinformation across politics, health, science, and consumer topics. Comparable as an established global fact-checking brand with similar verification workflow and IFCN certification, though single-organization model differs from Comprova's coalition structure.

Others

• International Fact-Checking Network (IFCN): Industry body housed at Poynter Institute that certifies fact-checking organizations including Comprova through its Code of Principles. Serves as the umbrella network for the global fact-checking community and the certification framework that platforms rely on for content moderation partnerships.
• Abraji (Associação Brasileira de Jornalismo Investigativo): Brazilian Association of Investigative Journalism that coordinates and houses Comprova as a project. Parent organization with overlapping mission in investigative journalism training and ethics, providing institutional infrastructure and member newsroom relationships that Comprova leverages.

Regional players

• Maldita.es: Spanish fact-checking organization founded in 2018 with methodology and operational model highly comparable to Comprova, including collaborative verification and media literacy programs. Comparable as a peer fact-checker in another major market with similar European/Latin misinformation dynamics.

Direct peers

• Aos Fatos: Brazilian fact-checking organization founded in 2018 that rates and publishes verification reports on Brazilian political, health, and public policy claims. Operates in the same Brazilian fact-checking space as Comprova with overlapping coverage of election-related misinformation and comparable IFCN certification status.
• Agência Lupa: Brazilian fact-checking agency owned by piauí magazine that publishes verification reports and analysis of Brazilian political discourse. Directly competes with Comprova in the Brazilian fact-checking category with similar methodology and audience targets.
• AFP Fact Check: Global fact-checking operation of Agence France-Presse that publishes multilingual verification reports including Brazilian Portuguese coverage. AFP is also a participating newsroom in the Comprova network, making it both a partner and a parallel publisher of Brazilian fact-checks.

Emerging players
