   Funciones

   SAML SSO. It can carry a stretch of the work, then wait. A person still approves anything that leaves the building.

   Qué dicen

   Litigantes en r/biglaw dicen que Harvey basta para trabajo de cliente cuando el despacho no permite un chatbot público, y mencionan revisión y detección de contradicciones.

   En r/legaltech, quien hizo una prueba dice que la venta fue pesada y que el producto parecía una capa fina sobre GPT. La queja es el precio, no una lista de funciones que falten.

   • “I find Harvey invaluable in my work (I’m a litigator). I think that ChatGPT performs better, but Harvey is more than good enough, and we’re not authorized to use public models with client materials.”

     Reddit

   • “For the price, complete bullshit. the sales team oversells like crazy, but under the hood it’s just a thin UI on top of GPT with a prompt sheet and some document storage.”
