Developed by former BigLaw M&A attorneys Madison Keeble and Geetika Jerath, the platform aims to capture the tacit knowledge that traditionally requires years of on-the-job observation to master. The system operates through three specialized modes: a mentor mode for 24/7 guidance, a tutor mode for personalized deal-work simulations, and an interview mode designed to prepare students for high-stakes partner questioning. By facilitating unlimited repetitions in a controlled environment, rubi seeks to bridge the gap between classroom theory and the fast-paced demands of transactional legal practice.

Texas Law has integrated the tool into its Law and Business Program, providing access to every incoming student this fall. Similarly, the Corporate Institute at the University of Minnesota Law School is utilizing the platform to complement its existing clinical and externship offerings. According to Vishal Sivamani, a rising 2L at the University of Chicago Law School, the ability to practice underlying legal tasks provides a necessary foundation for effectively supervising AI tools in future practice. The platform is currently available for institutional adoption and individual purchase, signaling a shift in how law schools and firms approach the training of the next generation of associates.
