What Are These Datasets?
The Atticus Project creates free, open-source datasets that teach AI systems to understand contracts. Each dataset contains real contracts and expert-labeled examples, allowing researchers and companies to build better legal AI tools. All datasets are released under CC BY 4.0 — completely free to download, use, and share.
