Confidentiality Is the Next Hallucination: AI Client Confidentiality for Lawyers
Fake AI citations went from curiosity to a docket of thousands. AI client confidentiality is on the same curve. The triggers, our forecast and four controls.
This is where we take legal AI apart and test what actually holds up. The section covers model benchmarks, tool reviews, hallucination audits, and the architecture choices that separate a working legal system from a chatbot with a law-firm logo. Start with our 300-prompt benchmark of the best AI for legal work, the field guide to AI lawyer apps in 2026, and our independent legal-AI hallucination audit. If you are evaluating vendors, deciding whether your firm can use AI at all, or trying to read past the marketing, these posts give you the numbers and the failure modes rather than the pitch.
