Andrew and the Marvellous Analytical Engine: A Practical Primer for Lawyers is a clear, practical guide to artificial intelligence for lawyers who want to understand the technology without becoming computer scientists. Drawing on the history of computing from Babbage and Lovelace to modern large language models, Andrew Hogan explains what AI is, how it works, where it can help in legal practice, and where it can go badly wrong. The book considers legal research, drafting, litigation workflows, legal AI platforms, agentic systems, confidentiality, privilege, hallucinated authorities, professional duties and synthetic evidence.
Throughout, the emphasis in on practical use combined with professional judgment. Written from the perspective of a practising barrister, and illustrated with a distinctive steampunk visual world, the second edition is intended for solicitors, barristers, judges, trainees and other legal professionals seeking a sensible introduction to AI. The central message is simple: use the machine, check the machine, remain responsible.
