An AI harness is the machinery that lets AI act on a case instead of just answering questions about it. Here is what the first one built for personal injury does, and why it had to be built where the client is.
The most interesting use of AI agents in PI is not replacing attorney judgment. It is building software that can remember the case well enough to help move it forward.
AI can cut an hour off a demand letter draft. It can also cost you $50,000 in settlement value if you use it wrong. A field guide to the workflow that actually works.
