This is correct usage. Letting it draft notes and letters is not. (Procedural emails, why not.) Essentially, ChatGPT Pro lets one do e-discovery and preliminary drafting to a degree that’s good enough for anything less than a few million dollars.
I’ve worked with startups in San Francisco, where lawyers readily take cases on contingency because they’re so easy to win. The only times I’ve urged companies fight back have been recently, because the emails and notes the employee sent were clearly LLM generated and materially false in one instance. That let, in the one case that they insisted on pursuing, the entire corpus of claims be put under doubt and dismissed. Again, in San Francisco, a notoriously employee-friendly jurisdiction.
I’ve invested in legal AI efforts. I’d be thrilled if their current crop of AIs were my adversary in any case. (I’d also take the bet on ignoring an LLM-drafted complaint more than a written one, lawyer or not.)
