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. Ce qu'on en dit Des plaideurs sur r/biglaw disent que Harvey suffit pour le travail client quand le cabinet interdit un chatbot public, et ils citent la relecture et la détection de contradictions. Sur r/legaltech, un utilisateur de pilote dit que la vente était lourde et que le produit semblait une fine interface sur GPT. La plainte est le prix, pas une liste de fonctions manquantes. - “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.”Reddit · u/tulumtimes2425 Tarif et fonctions de Harvey/Alternatives à Harvey 2 ### Legora Law firms and in-house teams that want agentic workflows across research, review, and delivery. Legora describes itself as collaborative AI for lawyers, with the Legora aOS connecting information, communication, and execution of legal work. Its Agent plans, executes, reviews, and delivers work, and the product list includes a Word add-in, Outlook add-in, tabular review, legal research, and a portal. Ce qu'on en dit Sur r/legaltech, une comparaison dit que Legora semblait plus simple que Harvey pour un petit cabinet. Le même commentaire le juge plus limité, et un autre dit que ce n’est pas ce qu’un grand cabinet devrait acheter. - “Legora looked a bit easier to use but also more limited.”Reddit - “Harvey is a waste, too high of a price. Legora apparently isn't Enterprise ready if you're at a large law firm.”Reddit Tarif et fonctions de Legora/Alternatives à Legora 3 ### Spellbook Law firms and in-house teams that negotiate contracts in Microsoft Word. Spellbook reviews and drafts contracts and applies playbooks, with intake from email and Slack and a Word add-in plus an Associate multi-document agent. The company says it is trusted by 5,000+ legal teams and lists SOC 2 Type II, HIPAA, GDPR, and zero data retention with LLM providers. Ce qu'on en dit Un commentaire sur r/biglaw, de quelqu’un qui a quitté Harvey pour de plus petits outils, cite Spellbook parmi les endroits où il a atterri. Ce commentaire ne décrit pas un échec de Spellbook. Il dit qu’il faut encore relire le résultat soi-même. - “So I moved to smaller tools like Spellbook, AI Lawyer, and CoCounsel and it honestly felt like the same practical benefit with less fuss.”Reddit Tarif et fonctions de Spellbook/Alternatives à Spellbook 4 ### Paxton Litigation attorneys and small firms that want research and drafts tied to the case file.

CoCounsel is Thomson Reuters' AI for legal, tax, audit, compliance, and drafting work, grounded in its content and connected to Westlaw, Practical Law, Checkpoint, Microsoft 365, and document-management partners. The company says customer content and prompts are not used to train CoCounsel or the underlying models, and that OpenAI and Google calls use zero-retention APIs. Ce qu'on en dit Le même commentaire sur r/biglaw range CoCounsel avec les outils plus petits qui ont remplacé un siège Harvey pour la rédaction quotidienne. Dans ce fil, nous n’avons pas lu un échec distinct de CoCounsel. Le point commun est qu’une personne relit encore le brouillon. - “Still have to review everything yourself either way.”Reddit Tarif et fonctions de CoCounsel/Alternatives à CoCounsel 7 ### Lexis+ AI Attorneys who want drafting and research grounded in LexisNexis authority and Shepard's. The Lexis+ with Protégé free-trial page, which describes the product formerly presented as Lexis+ AI, says it accelerates research, drafting, and analysis grounded in LexisNexis content and Shepard's citations.
