The eight tools here split into two kinds. Four are general document automation: Clio Draft turns Word files into fillable templates, pre-fills court forms from the matter and sends client questionnaires, with built-in AI that converts existing Word documents into reusable templates, priced by quote; Gavel generates Word and PDF documents from client-facing forms from $83/mo on its Lite plan billed annually; XpressDox builds templates directly in Microsoft Word at $59.00/user/mo on its Essential plan; and Legito offers a free workspace and prices its full platform by quote, with Kedy AI converting Word documents into automated templates. The other four are estate-planning tools: Luminary and Vanilla read existing trusts and wills into source-cited summaries, diagrams and client deliverables, both by quote; Trust & Will EstateOS, which is free to use, extracts beneficiaries, trustees and provisions from uploaded plans and routes referrals, and is built for analysis rather than drafting; and Wealth Docx comes in WealthCounsel membership bundles, priced by quote, with the LawY AI assistant included.
Across the set the AI does the variable parts: it turns a firm's own Word documents into templates, extracts the names, dates and provisions from documents already on file, answers questions about the workspace, and drafts the summary or the first draft from the template. Posted prices run from free (Trust & Will EstateOS and Legito's free workspace) to $59.00/user/mo and $83/mo, five of the eight are quoted, and every figure was read on the vendor's own site on October 31, 2026. Four of the eight vendors post that client data is not used to train their AI models and name a standard: Clio Draft, Gavel and Luminary name SOC 2 Type II, and Legito names ISO/IEC 27001; Trust & Will EstateOS and Vanilla post a SOC 2 statement but no statement about training. Among practice platforms, Clio Draft and Gavel list Clio as an integration, Wealth Docx lists LEAP, and XpressDox lists iManage, NetDocuments and DocuSign alongside Microsoft Word.
