Summary

Will Chen, a former Latham & Watkins lawyer, launched Mike, an open-source legal AI platform, which has generated significant online discussion. Mike offers core functions similar to commercial platforms like Hargora, including document review, creation, editing, project management, tabular review, and workflow capabilities. Chen highlights Mike's ability to properly render documents in landscape, make precise tracked changes, and replicate documents across multiple files simultaneously. While the web app at mikeoss.com is a demo, the platform is designed for firms to implement locally or on their intranet, enhancing security by keeping client files in-house. Mike aims to provide an accessible, affordable alternative to expensive, closed legal AI systems, particularly for small and medium-sized law firms, and garnered over 1000 GitHub stars and 300 forks within 72 hours of its launch.
