Over the last few weeks, we've seen a growing focus on how we evaluate legal AI tools. The latest contribution is the Vals Legal AI Report, which gives an in-depth study of four popular legal AI tools across tasks like data extraction, summarisation, and chronology creation. This is very welcome: the pace of development of AI tools shows no signs of slowing down and many law firms are grappling with which solutions to spend time, energy, and money on. However, less has been written about evaluating AIlegal drafting. With that in mind, we wanted to explore the challenges involved and share some practical steps for effective evaluation of AI drafting tools.
