Why Law Firms Need Agents & How We Built Them: An AWS Event
Why agents (not chatbots) are the right shape of AI for law firms, and what we presented at the AWS event in London.
At a recent AWS event in London, we shared the architectural principles behind the agents we've built into the FinLegal platform.
Why agents, not chatbots
Chatbots are open-ended. Legal work isn't. Firms need systems that can take structured inputs (a cohort of matters, a set of criteria, a library of precedent) and produce structured, auditable outputs.
Agents are the right shape because they combine reasoning with tools. They can query the matter database, retrieve documents, run analyses and generate outputs — each step logged and verifiable.
The design principles
- One agent, one job. Don't ask a single agent to do everything — decompose the task.
- Cite every claim. Outputs without source citations can't be defended.
- Humans in the loop. The fee-earner approves, the AI accelerates.
- Your data, your control. No training on client data, no cross-firm leakage.
