We are in the midst of a revolution in the way legal practice is being conducted. Traditionally, lawyers consulted practitioners’ texts, reviewed the applicable cases and used their firm’s available models to craft their work product. The move from paper to online sources did not essentially alter this; it merely expanded the resources that were available as even small firms could now consult most standard primary and secondary sources via Lexis or Westlaw. With AI the game has radically changed. Now statutes, cases, practitioners’ texts and vast numbers of documents can be fed to AI systems all at once to provide an analysis within minutes. Work product of all kinds can be fed to AI systems to check for internal consistency, verify citation, to synthesise or simply to improve clarity and presentation.
