Alternatives to Definely

{"intro": "Definely is a paid suite for lawyers creating, drafting, and reviewing complex contracts in Word. Read keeps defined terms and cross-references available within the clause, while Definitions Report identifies defined, undefined, and unused terms. Proof checks incomplete information, formatting, and spacing; Cascade maps clauses, definitions, and references that changes may affect; Enhance answers natural-language questions with clause and definition references; and Vault connects to document-management systems for precedent reuse. It runs on macOS, web, and Windows, supports Microsoft Word and PDF, and offers a Mac 14-day trial.\n\nAn alternative may fit better if you need broader drafting and negotiation, specialized transaction diligence, repository analysis, or access through other tools. Definely pricing is on request, and Draft and Proof currently work in English and Swedish. Compare each option’s workflow, integrations, supported languages, deployment, and review style. Consider whether you need playbooks, tracked redlines, extraction APIs, obligation management, cited research, or a free plan alongside Definely’s contract-focused Word suite.", "rows": [{"ref": "sw:genie-ai", "name": "Genie AI", "best_for": "Business teams drafting, reviewing, and negotiating agreements", "pricing": "Free plan; paid from $59/mo (annual)", "key_difference": "Genie adds plain-English drafting, tracked redlines, document data tables, and broad business-system integrations.", "choose_when": "Choose it for a freemium workflow spanning drafting, negotiation, extraction, and email, CRM, storage, or eSign connections."}, {"ref": "sw:legartis", "name": "Legartis", "best_for": "Companies running standardized legal workflows", "pricing": "Free plan; 14-day trial", "key_difference": "Legartis adds an agentic workspace with intake-to-signature workflows, custom playbooks, scheduled insights, and European hosting.", "choose_when": "Choose it when company standards, approvals, custom playbooks, and contract deadlines matter more than Definely’s Word-centered tools."}, {"ref": "sw:zuva", "name": "Zuva", "best_for": "M&A diligence and contract data extraction", "pricing": "Free plan; paid from $1.25", "key_difference": "Zuva focuses on sell-side diligence, bidder questions, extraction workflows, and a deployable API rather than lawyer-focused Word tools.", "choose_when": "Choose it for transaction reviews, Excel or Word outputs, large document-type coverage, or cloud and self-hosted API deployment."}, {"ref": "sw:lecheck", "name": "LeCHECK", "best_for": "Japanese legal teams reviewing and researching contracts", "pricing": "Pricing on request", "key_difference": "LeCHECK combines risky-clause review with similar-contract comparison, translation, matter management, and cited research in Lisse Legal AI Cowork.", "choose_when": "Choose it when contract templates, registered precedents, Japanese legal research, or broader legal-work functions are priorities."}, {"ref": "sw:thoughtriver", "name": "ThoughtRiver", "best_for": "Playbook-based review across Microsoft tools", "pricing": "From $6/mo · 28-day trial", "key_difference": "ThoughtRiver centers review on lawyer-built concepts and Playbooks, with style-mimicking editing inside Outlook, Word, and Teams.", "choose_when": "Choose it for preset issue criteria, unmet-provision outputs, redlining, and review access through email or Microsoft applications."}, {"ref": "sw:robin-ai", "name": "Robin AI", "best_for": "Repository analysis and obligation management", "pricing": "Pricing on request", "key_difference": "Robin adds clickable source citations, repository analysis, renewal dashboards, and legal AI supporting over 200 languages.", "choose_when": "Choose it when verifiable answers, live precedent editing, deadline workflows, or broad language support outweigh Definely’s contract tools."}, {"ref": "sw:spellbook", "name": "Spellbook", "best_for": "Legal teams needing cited drafting and review in Word", "pricing": "Pricing on request · 7-day trial", "key_difference": "Spellbook adds jurisdiction-aware drafting, cited legal research, reusable playbooks, extensive storage integrations, and zero LLM data retention.", "choose_when": "Choose it for Microsoft Word redlines, precedent-based drafting, cited research, or integrations with iManage, drives, Slack, and Google Docs."}]}
