Go further than a single tool
AI for Lawyers 2026 covers the tools worth using, the regulation and 100 practical prompts across nine practice areas. The Professional Programme teaches the method live, on real legal scenarios.
Reading the result honestly
This is a planning estimate, not a forecast. The two assumptions that matter most are the hours genuinely spent on AI-suitable work and the percentage saved. Both depend less on the tool than on how well your lawyers are trained to use it — which is why the same software can transform one firm and disappoint another.
- Hourly billing: time saved only creates value if it is reinvested in other billable or higher-value work. Fees must remain reasonable — ABA Formal Opinion 512 addresses this directly.
- Fixed fees and in-house teams: time saved flows more directly into margin or capacity.
- Hidden costs: training, policy work, verification time and change management. Budget for them.
Run a pilot before a rollout
Choose three to five lawyers, two or three well-defined tasks, and a four-to-six week window. Record time before and after. Replace the slider value above with what you actually measured. For help choosing what to pilot, see the best AI tools for lawyers in 2026 — and for training that makes pilots succeed, our organisational programmes.
Frequently asked questions
How much time does AI save lawyers?
It depends heavily on the task and training. Plan conservatively at 10–20% on AI-suitable tasks and validate with a pilot.
Is time saved the same as money saved?
Not under hourly billing, unless the time is reinvested. It is closer to direct value for fixed-fee work and in-house teams.
