An AI tool built only for legal work that researches case law, reviews contracts, and analyzes large document sets for law firms and in-house teams.
An AI tool for legal document review that drafts, negotiates, and checks contracts inside Word, built for large firms with frequent, high-value deals.
Luminance is an AI tool for contract and document review. Lawyers use it to draft contracts, review and negotiate them inside Microsoft Word, check company-wide compliance, and speed up document review for litigation and due diligence. Luminance calls its accuracy approach a Panel of Judges, which checks answers across several AI models before giving a result, and the company reports it can review an 80-page contract in under five minutes. It is made by the UK company of the same name, holds ISO 27001 and SOC 2 Type II certifications, and counts more than 1,000 customers, including AMD and Staples.
This fits a large firm or legal team with a steady flow of high-value contracts or deals; reviewers describe it as sized and priced for big law firms and large enterprise legal teams, not small ones. Luminance does not publish pricing; third-party reports put licenses at $40,000 to $60,000 a year for a typical deployment and more for larger ones, so treat that as a planning estimate and get a quote scoped to your document volume. A good starting point is a pilot on one deal type, like M&A due diligence, before wider use. The main risk is cost and fit, since the tool is built for high contract volume and a smaller legal team may find it more than they need.
These estimates cover licensing, setup, integrations, staff time, security, administration, and support.

Estimate assumptions: Based on 1 production workspace. This is a planning allowance, not verified product pricing. Confirm the vendor’s billing unit and current price or quote before budgeting.
Benefits have not been estimated: The current research does not estimate potential savings, return on investment, or how long it would take to recover the cost. Earlier benefit estimates are excluded.
Confirm current product identity, commercial packaging, data processing terms, sign-in and access rules, retention, integrations, support model, implementation effort, and rollback conditions.
Verify identity, package, availability, ownership, pricing, and security evidence before approving a pilot
Do not approve a pilot yet. Verify the current product identity, package, availability, owner, pricing, and security evidence; then define one workflow, a baseline, and rollback criteria.
Define what success looks like for a test of Luminance and assign someone to lead it.
Once the requirements above are met, compare a small trial with how your team works today.
Track adoption, output quality, business results, and actual costs against the estimate.
Use the results to decide whether to stop, adjust, or expand the pilot.
Confirm encryption, how the vendor uses your data, customer data separation, how long data stays and how to delete it, activity records, sign-in and user setup, where data is handled, other companies that process data, past incidents, and what your team must manage.
Review before rollout: confirm how to export your data, revoke access, and return to your existing workflow. Assign an owner and test the rollback plan before expanding use.
