What is Luminance?
Luminance is a legal AI platform developed by a company founded by Cambridge University machine learning researchers. It automates core legal processes including contract review, due diligence, drafting, and negotiation support. Adopted in 60+ countries by 700+ law firms and corporate legal departments, it's a leader in the legal AI space. The "Autopilot" feature released in 2023 significantly raised the bar for legal AI. It autonomously reads contracts, detects risk clauses, compares against market standards, suggests revisions, and auto-generates drafts. Contract reviews that took lawyers hours can be completed in minutes. It covers the entire contract lifecycle: drafting (AI auto-generates from templates based on conditions), review (auto-detection of risk clauses, deviations, and unfavorable terms), negotiation support (revision history analysis, negotiation point suggestions), and management (contract database, renewal alerts, condition search). For due diligence, where thousands to tens of thousands of contracts must be reviewed in short timeframes for M&A deals, Luminance dramatically improves efficiency. AI auto-detects and flags Change of Control clauses, restrictive provisions, and potential risks. It supports 80+ languages for cross-border matters. Its legal-specific AI model deeply understands legal terminology, writing style, and logical structures, capturing legal nuances that general-purpose AI might miss. ISO 27001 and SOC 2 Type II certified for secure handling of confidential legal documents. On-premises deployment is also available.

How to get started with Luminance
A practical, five-step path we recommend for anyone evaluating Luminance for the first time — designed to minimise wasted time and help you decide fast.
1Sign up for Luminance
Head to the official Luminance website and create an account. You can start with the free plan without entering payment details, which is ideal for testing how it fits your workflow.
2Set up your workspace
Install the app on web if a native client is available, or simply open it in your browser. Configure basic preferences such as language, notifications, and default output style so that subsequent runs feel consistent.
3Run your first task with Autopilot (autonomous contract review and revision suggestions)
Start with a small, low-stakes task to understand how Luminance responds. Write a clear prompt or input, review the output, and iterate. This low-risk exploration is the fastest way to build intuition for what the tool excels at.
4Integrate into your daily workflow
Once you know its strengths, introduce Luminance into one concrete workflow — not ten. Replace one existing step with it and measure the time saved or quality gained over a week before expanding usage further.
5Upgrade based on real usage
Rather than upgrading upfront, monitor which limits you actually hit (message count, output length, export features). Upgrade only when a specific limit blocks your productivity, not because the higher plan looks more attractive on paper.
