AI-assisted case law research for briefs

There was a recent decision in US that said AI prompts were disclosable in litigation as they didn't attract privilege (I have incredibly oversimplified this)

Whilst we are a completely different jurisdiction and have different rules on privilege, but this serves as a good warning.

Spoiler - lawyers use AI, personally I use two different AI tools (one attached to a legal research database and the other on my case management system) both cost a huge amount of money per year compared to the open-source products and also have GDPR compliant data controls (unlike open source). But I know how the free/low cost alternatives have been useful to many litigants. So don't stop, but be wise, just in case we somehow follow the US court's lead, this would include:
- no telling AI your settlement expectations
- no writing anything you wouldn't want your opponent or courts to see
- if you're uploading documents to analyse make sure it is a document that is in circulation or that you will be disclosing
- turn off the feature that allows the chat to train other models

Lawyers on this page, can you think of any other tips?

Civil lit, solo and sharing this because I've been sitting on it feeling quietly mortified and maybe sharing so no one makes a similar mistake may be useful. Motion for summary judgment, damages issue, used AI to help pull supporting case law, running behind and the citation looked completely legitimate, right format, plausible jurisdiction, reasonable year, case name that tracked with the argument, I read the summary and it made sense so I moved on. Opposing counsel flagged it in their response, the case does not exist. No sanctions, OC was reasonable about it, I filed a corrected brief, life went on. But I submitted a motion with a fabricated citation to a federal court and the only reason it's not a Mata v. Avianca situation is that opposing counsel decided not to make it one, which is not a process control I want to rely on. Every single AI citation gets checked against Westlaw now before it goes anywhere near a filing, no exceptions, especially not when I'm behind, because that's exactly when mistake happens and exactly when I'm most tempted to skip the verification step.
