Harvey
Large law firms and corporate legal departments running high-stakes work on one platform.
Harvey is an AI platform for law firms and in-house teams, with agents, shared Spaces, a document Vault, contract intelligence, and a command center for usage. The site says more than 3,000 legal organizations use it and that default controls include SAML SSO, audit logs, IP allow-listing, and data lifecycle management.
- Preço
- Not published
- No price, plan, or free trial is listed on the homepage opened. Access is presented through the product site rather than a public rate card. Last checked 5 October 2026.
- Recursos
- SAML SSO. It can carry a stretch of the work, then wait. A person still approves anything that leaves the building.
O que dizem
Litigantes no r/biglaw dizem que o Harvey basta para trabalho de cliente quando o escritório não permite um chatbot público, e citam revisão e checagem de contradições.
No r/legaltech, quem fez um piloto diz que a venda foi pesada e que o produto parecia uma interface fina sobre o GPT. A reclamação é o preço, não uma lista de funções faltando.
“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.”

O que dizem
Um comentário no r/biglaw de quem saiu do Harvey para ferramentas menores cita o Spellbook como um dos lugares onde parou.
Esse comentário não descreve uma falha do Spellbook. Diz que ainda é preciso revisar o resultado.
“So I moved to smaller tools like Spellbook, AI Lawyer, and CoCounsel and it honestly felt like the same practical benefit with less fuss.”
