Some lawyers have a tendency to think of artificial intelligence (AI) as something akin to cellphones in the 1980s or computers in the 1970s. That is to say, expensive enough that only the law firms or legal departments with the deepest pockets can tap into its nebulous potential.

But AI is far from a mysterious or inaccessible innovation. For years, it has powered online chatbots and search engines, voice-activated assistants and video games. And most of these are widely available and affordable. So why shouldn’t it be the same for the legal industry?
