Fit
Best For & Not For
Luminance
✅ Best For
✅Enterprise legal, compliance, procurement, and HR teams at global companies that need a single AI platform to handle contracts across every business function, not just legal, with the accuracy and security that sensitive commercial agreements demand.
✅Multinational corporations that operate across multiple jurisdictions and need AI that can handle regulatory compliance monitoring, cross-departmental contract workflows, and bulk analysis of legacy contract repositories.
❌ Not For
❌Startups and small businesses that need a lightweight, self-serve contract review tool, as Luminance is architected and priced for enterprise deployments with dedicated implementation support.
❌Teams looking primarily for litigation research or case management tools, as Luminance is focused on the contract lifecycle and compliance surface rather than litigation workflow.
Westlaw
✅ Best For
✅Attorneys at law firms and corporate legal departments who need access to the most comprehensive and accurate legal research database available, with AI tools that surface verified answers and cite-check every source automatically.
✅Litigators and appellate attorneys who rely on KeyCite to verify authority, judge analytics to inform case strategy, and litigation document analysis to surface counterarguments and gaps in opposing briefs.
❌ Not For
❌Solo practitioners and small firms on tight budgets who need basic legal research at a lower price point, as Westlaw is a premium-priced subscription that may exceed the research budget of very small practices.
❌Teams looking for a contract lifecycle management or drafting-focused AI tool, as Westlaw is fundamentally a legal research and authority verification platform rather than a contracting or document automation system.
