The Shift from Passive to Proactive Legal AI

By Matthew Leopold, LexisNexis.

Most legal AI today still behaves like a vending machine. Feed in a prompt, wait, and hope the output resembles something useful. If you’re lucky, it does. If not, you’re fiddling wiht the buttons or slamming the side of the machine wondering where it all went wrong.

but law doesn’t work like that.

Legal reasoning is rarely linear. it builds in layers; part logic, part instinct and with plenty of meandering detours along the way. Lawyers shape ideas, test hunches and chew over problems. Yet most legal tech tools remain passive,waiting to be told what to do.

Which makes them impressive, but frustratingly static.

Generative AI has come a long way. Lexis+ AI, for instance, set a new standard when it launched. It can summarise, draft and research in seconds, complete with links to underlying citations. But even with the best tools, lawyers can still find themselves doing the heavy lifting, notably with generic, non-legal models.

Ask the wrong question, and you’re stuck rewording the same prompt five different ways. Guide it too little, and it misses the point. Guide it too much, and you might as well have done it yourself.

This is where things begin to shift.

From Passive to Proactive

A new generation of legal tools is starting to behave differently. Not by waiting for instructions – but by offering them.

Protégé is the next evolution in the Lexis+ AI journey. Freshly launched in the UK, it’s a generative AI assistant designed with agentic capabilities. In plain terms? It doesn’t just answer your questions.It sees what you’re working on and suggests what comes next.

Start asking a research question and Protégé will offer suggestions and follow on questions. Not becuase you asked.Because it’s spotted what you might need.

It’s not a vending machine.It’s more like a switched-on trainee. The one who’s been quietly prepping documents while you were on a call.

Fewer Switches, More Momentum

This isn’t about speed. It’s about the cost of context-switching.

Most lawyers spend their day bouncing between tasks. Not just mentally, but digitally. Drafting, prompting, clarifying, formatting. Switching tools.reframing c
