Had a chance to try Westlaw Advantage. It sucks.

I've been able to try most legal "AI" services, but decided to do some tests with WL Advantage, which I haven't used. It's absolutely horrible. No nuance to understanding filings. Suggests defenses and counterarguments that would fail in court because the counterarguments/defenses miss key facts that distinguish the cases I provided from the counterarguments/defenses. When I used the Claims Explorer, it pulled in claims that weren't applicable, and not a single claim that I had been able to find in my own research was there. Building out my own databases using CC yields much better answers than WL, and in less than the 15-30 minutes it seems to take for WL AI to return an answer. The only things WL and LN hold of any value are case law and secondary sources, but even that gate is being broken down as more free-access law databases become available. I guess I expected it to have some "wow" factor, but not "wow, this sucks." These companies have to see the writing on the wall that their value is sinking fast.
