Doppelcheck, a browser-based AI tool, facilitates fact-checking for journalists and enables a quick assessment of the credibility of information.


Doppelcheck is a browser-based tool designed as an AI assistant for fact-checking in journalism. The slogan "Individual press review at the push of a button" encapsulates the goal of simplifying the validation process for journalists and ensuring that they can quickly assess the credibility of information and easily identify biased texts.

The Open Source Solution


In a time when generative AI is spreading rapidly, misinformation and disinformation pose a significant challenge to the media industry. Journalists are faced with the enormous task of identifying credible sources from a flood of data. Doppelcheck addresses the need for a reliable tool that automates the detection of disinformation and biased reports, facilitating integrity in journalistic work.


The idea behind Doppelcheck is to provide a comprehensive solution for journalists to facilitate research and text analysis. By integrating various APIs, language models, data sources, and analysis tools, a modular system is envisioned. This system aims to efficiently assist journalists in fact-checking and debunking false narratives.


Doppelcheck's solution comprises key features such as the Keypoint Assistant, which extracts and highlights the main points of a text, and the Sourcefinder Assistant, which searches for relevant documents from external and internal sources. The Crosschecker Assistant then compares the main points with these documents to assess their consistency, providing journalists with a robust tool for their investigative needs.
