Description

ClaimBuster serves as the overarching platform for all fact-checking initiatives within the IDIR Lab. Originally launched to develop an AI system capable of identifying claims that warrant verification, it has progressively advanced towards achieving the ideal of fully automated fact-checking. While journalists primarily utilize ClaimBuster, it is designed for anyone motivated to confront misinformation. Accessing our models is straightforward through our API, which only requires the registration of a free API key. The success of ClaimBuster relies heavily on the contributions from individuals who label data. We encourage you to create an account and participate in labeling to enhance our model's effectiveness. Additionally, we've made our machine learning model training code available as open-source, inviting skilled AI engineers to contribute their expertise. Our claim-detection model even retweets posts it identifies as potentially needing fact-checking, expanding its utility in real-time. By participating, you can play an essential role in the ongoing battle against misinformation.

Description

Lenz is a robust API designed for audit-level fact-checking of AI-generated content, aimed at teams that require verification of factual assertions prior to presentation to clients or customers. This tool analyzes various forms of text, such as drafts, memos, or model answers, identifying factual claims that can be substantiated by credible public sources and providing a detailed outcome for each assertion. Its operational framework is built upon four key API functions: extracting claims that can be verified, performing a rapid multi-model assessment of these claims in bulk, elevating ambiguous statements to a comprehensive verification process, and facilitating follow-up inquiries that are based on the verification findings. The complete verification process is structured into five distinct stages: defining the issue, conducting research, engaging in debate, undergoing a panel review, and reaching a conclusion. Lenz meticulously searches through public information, evaluating evidence based on factors like authority, relevance, and timeliness, while also employing models from various vendors to present arguments for both sides of a claim. Ultimately, it delivers a verdict, a confidence score, references to cited sources, and a trace of the reasoning that allows users to conduct their own audits, ensuring transparency and reliability. With Lenz, teams can enhance their decision-making processes by ensuring all claims are thoroughly vetted before they reach their audience.
