Who This Guide Is For (and How to Read It)
The Legal Map
AI tools arrived in legal work faster than most firms could write a policy for them. The Thomson Reuters 2026 AI in Professional Services Report (opens in a new tab) found that 41% of law firms and 47% of corporate legal departments say their legal teams are using GenAI, up from 28% and 23% respectively in 2025. Broader surveys report even higher numbers. The figure depends heavily on how the question is asked: survey design moves the answer from 26% to 92% .
Adoption
Lawyers are already using it.

Adoption is rising fast. Understanding comes next.
Thomson Reuters, AI in Professional Services Report (2025, 2026). Surveys that count any AI tool, not only generative AI, report much higher figures. Definitions matter.
This guide is a plain-language map: what the tools do, where they fail, what the rules say, and how to begin. No technical background required.
Who it is for
Lawyers and the people who work with them: partners and associates, in-house counsel, judges, legal operations, paralegals, students. Whether you use AI daily or have never opened a chatbot, the guide starts from what you already know: legal work.
It won't sell you a tool, and it isn't advice on your own professional rules. It gives you the questions to ask, the sources behind each answer, and enough understanding to judge the rest yourself.
How to read it
- Read in order, or jump to your question. Eight chapters, one for each question lawyers keep asking. Every lesson stands alone.
- Lessons take a few minutes. Your progress is saved in this browser.
- Hover or tap a dotted term, like hallucination, for a short definition. All terms are also in the survival glossary.
- Every figure links to a dated source. AI moves fast; a six-month-old claim may already be stale.
- Try the interactive examples. Where data is illustrative rather than measured, the example says so.
