Luminance offers 3 pricing tiers: Professional, Enterprise, Enterprise Plus (AI Agents). The Enterprise plan is large enterprises and law firms needing ai-powered contract lifecycle management with autonomous agents, compliance modules, and custom deployment options.
Compared to other ai legal tools software, Luminance is positioned at the mid-market price point.
Luminance is an AI-powered contract intelligence platform built by mathematicians from Cambridge University, now serving over 700 organizations across 70 countries. Unlike general-purpose legal AI tools, Luminance uses proprietary Legal-Grade AI trained on over 150 million verified legal documents to automate contract review, risk detection, negotiation, and compliance. In 2025, Luminance introduced autonomous AI agents capable of drafting, negotiating, and completing contract tasks without human oversight -- a first in the legal AI space.
Pricing is custom and based on contract database size, with per-user estimates ranging from $10-$100/user/month depending on organization size and features. Luminance does not publish fixed pricing tiers. Annual contracts for mid-size legal teams typically range from $20,000-$100,000+, while large enterprises with autonomous AI agent capabilities can expect $100,000-$500,000+ per year. Luminance raised $75 million in 2025, bringing total funding to $165 million, reflecting strong enterprise demand.
Key considerations before purchasing: Luminance's database-size pricing model can lead to cost escalation as you digitize more contracts, advanced AI agent features are premium add-ons above the base platform, and on-premise deployments incur additional infrastructure costs. However, Luminance's plug-and-play deployment (some customers operational within 24 hours), 80+ language support, and autonomous negotiation agents make it a compelling choice for organizations managing large, multilingual contract portfolios.
In this 2026 pricing guide, we break down Luminance's enterprise pricing model, identify hidden costs like database scaling and agent add-ons, compare Luminance to alternatives like Harvey AI, CoCounsel, Ironclad, and Kira Systems, and help you determine if Luminance is the right contract intelligence platform for your organization.

Frequently Asked Questions
01 How much does Luminance cost?
Luminance uses custom enterprise pricing based on the size of your contract database rather than a fixed per-seat rate. Industry estimates place costs at $10-$100 per user per month depending on organization size and features selected. Luminance does not publish fixed pricing tiers and requires you to contact their sales team for a custom quote. Annual contracts for mid-size legal teams typically range from $20,000-$100,000+, while large enterprises can expect $100,000-$500,000+ per year.
02 Is Luminance free?
No, Luminance does not offer a free plan or a standard free trial. The platform is designed for enterprise and mid-market legal teams and requires a custom subscription. You can request a demo through their website to see the platform in action before committing. For free or low-cost alternatives, consider Clio's AI features (starting at $39/user/month) or general-purpose AI tools like ChatGPT Plus ($20/month).
03 What is Luminance?
Luminance is an AI-powered contract intelligence platform founded by mathematicians from Cambridge University. It uses a proprietary Legal-Grade AI trained on over 150 million verified legal documents to automate contract review, negotiation, and compliance. Luminance serves over 700 organizations across 70 countries and supports 80+ languages. In 2025, Luminance launched autonomous AI agents that can draft, negotiate, and complete contract tasks without human oversight.
04 How does Luminance pricing work?
Luminance prices based on the size of your contract database rather than a traditional per-seat model. This means costs scale with the volume of contracts you store and analyze rather than the number of users accessing the platform. This model makes Luminance accessible to smaller teams with large contract volumes, but it also means costs can escalate as you digitize more legacy contracts. Volume discounts are available for larger organizations.
05 Luminance vs Harvey AI: which is better?
Luminance and Harvey AI serve different primary use cases. Luminance specializes in contract intelligence -- automated review, anomaly detection, negotiation, and compliance across your contract portfolio. Harvey AI focuses on broader legal research, memo drafting, and case law analysis. Luminance is stronger for organizations with large contract volumes needing lifecycle management, while Harvey AI is better for firms needing AI-assisted legal research and document generation. Luminance also offers autonomous AI agents for contract negotiation, a capability Harvey does not yet match.
06 Luminance vs CoCounsel: which should I choose?
Choose Luminance if your primary need is contract intelligence, review, and lifecycle management across a large portfolio. Choose CoCounsel if you need AI-powered legal research integrated with Thomson Reuters content and Westlaw. CoCounsel starts at $220/user/month with no seat minimums, while Luminance uses database-size pricing requiring a custom quote. CoCounsel is more accessible for solo practitioners and small firms, while Luminance targets mid-market to enterprise legal teams with substantial contract volumes.
07 How long does it take to implement Luminance?
Luminance advertises near-instant cloud deployment, with some customers (like Clyde & Co) reportedly up and running within 24 hours. The platform is designed as plug-and-play, requiring no special technical skills. However, achieving optimal performance for specialized legal workflows may require additional data tagging, custom configuration, and user training that extends the effective implementation timeline to 2-6 weeks for full organizational adoption.
08 Does Luminance support multiple languages?
Yes, Luminance supports over 80 languages for contract review and analysis. The platform can process multilingual contracts without requiring separate configurations or add-ons. This makes Luminance particularly valuable for global organizations managing cross-border contracts and multi-jurisdictional compliance requirements. Multi-language support is included in all pricing tiers.
09 What are the alternatives to Luminance?
Key alternatives to Luminance include Harvey AI ($100-$500/user/month) for broader legal AI research and drafting, CoCounsel by Thomson Reuters ($220-$500/user/month) for AI legal research with Westlaw integration, Ironclad for contract lifecycle management with workflow automation, Kira Systems for AI contract review and due diligence, and Clio ($39-$139/user/month) for practice management with AI features. For organizations focused specifically on contract review and analysis, Kira Systems is the closest competitor in capabilities.
