The nine tools here split into three kinds. Four are the AI assistants built into a practice-management system, listed here because they answer questions across the whole firm's matters: Archie AI inside Smokeball, Clio Duo inside Clio Manage and LOIS by Filevine, which has a free LOIS Explore tier, all priced by quote; and MyCase IQ, included in MyCase plans from Pro at $100/user/mo billed annually, with the Case Assistant and Discovery Assistant on Advanced at $130/user/mo billed annually. Two are document and email management systems with AI on top: iManage Work, with Ask iManage, and NetDocuments ndMAX, with its Legal AI Assistant and AI Search, both quoted. Three are standalone assistants: CaseMark Para takes assignments by email, Teams, Slack or its web app and returns finished documents from a library of more than 1,200 workflows, at $20/seat/mo on Standard and $100/seat/mo on Pro; LawDroid Copilot comes in the LawDroid Ultra bundle with Builder intake bots at $1,188/Year after one free week; and AI Lawyer, a web and mobile assistant with a free trial, is priced by quote.
Across the set the AI puts the firm's own files behind a chat: it summarizes a matter or a document, flags discrepancies between documents, drafts replies in Outlook and edits in Word, checks a draft against the firm's playbooks, finds a file from a plain-language question, runs repeatable workflows such as deposition summaries and medical chronologies, and verifies the citations in its own research. Three of the nine post a price, from $20/seat/mo to $1,188/Year, and six are quoted, with LOIS by Filevine offering a free tier; every figure was read on the vendor's own site on October 31, 2026. Five of the nine vendors post that client data is not used to train their AI models and name a standard: CaseMark Para, Clio Duo, MyCase IQ and NetDocuments ndMAX name SOC 2 Type II, and Archie AI names ISO 27001:2022; LOIS by Filevine posts a SOC 2 Type II statement but no statement about training. CaseMark Para, Clio Duo and LawDroid Copilot list Clio as an integration, Archie AI and CaseMark Para list Smokeball, MyCase IQ lists MyCase, and NetDocuments ndMAX lists CoCounsel Legal, Lexis+ Protégé and Clearbrief.
