## Luminance

Luminance grew out of research at the University of Cambridge and has been building contract-focused AI for over a decade. Its core proposition is that contracts contain knowledge about how a business actually operates, and that knowledge should be visible to every team that depends on it, not just to lawyers who happen to open the file.

The platform covers three broad jobs. Discovery turns a contract portfolio into actionable insight by surfacing risk, obligations and commercial opportunities without manual searching. Negotiation brings precedent, playbooks and accepted positions into the drafting process so teams review faster and hold on to the terms that matter. Automation keeps contracts moving through connected intake-to-signature workflows that pull stakeholders and systems into one process.

Luminance positions itself as an enterprise-grade offering rather than a self-serve tool, and it reports use across Legal, Procurement, Finance, Sales and Executive teams, with over a thousand enterprises claimed as customers. It is designed around the breadth of contract types a large organisation holds, and around the compliance and audit expectations that come with that scale.

**Pricing & Plans:** Contact for pricing. Luminance does not publish plan details or per-seat rates; it runs a demo-led enterprise sales process and quotes per organisation.

- **Portfolio-wide contract discovery:** Turns a contract portfolio into searchable insight, surfacing risk, obligations and commercial opportunities in seconds rather than through manual review.
- **Negotiation with precedent and playbooks:** Brings prior positions, accepted clauses and negotiation playbooks into each review so teams move faster and protect the terms that carry risk.
- **Workflow automation from intake to signature:** Connects stakeholders, systems and actions into a single workflow so contracts keep progressing instead of stalling between teams.
- **Cross-functional access:** Delivers contract context to Legal, Procurement, Finance, Sales and Executive users, including supplier terms, auto-renewals and unrecognised commitments.
- **Purpose-built legal AI architecture:** Combines specialist legal models with contractual context so documents are understood in context rather than as plain text.

**Strengths:** Deep specialisation in contract intelligence rather than general-purpose document AI; Enterprise scale: used by organisations reporting thousands of users per company; Serves five different functions from one contract knowledge base; Backed by more than a decade of legal AI research and development

**Limitations:** No self-serve or published pricing, so smaller teams cannot evaluate it on their own; Implementation and onboarding are enterprise-scale and not suited to one-off projects; Value depends heavily on having a large existing contract portfolio to analyse

## Mike (MikeOSS)

Mike is an open-source legal AI platform aimed squarely at law firms that want the capability of commercial legal-AI suites without the per-seat licensing. Product materials position it as an alternative to Harvey and Legora, and the project has been built in the open with thousands of GitHub stars and public release notes. The core is an assistant that reads documents, answers with grounded citations rather than asserted references, researches case law, executes multi-step workflows, and drafts and edits contracts end to end.

Work is organised around matters. A project is a matter-scoped workspace where you upload credit agreements, share purchase agreements, NDAs, leases and diligence packs; the assistant keeps full context across every conversation and document in that project. Tabular review applies spreadsheet-style extraction across hundreds of documents in parallel, and each cell cites back to a specific page and quote so you can verify the answer instead of trusting it. On top of that, workflows let you save proven prompts — CP checklists, credit agreement summaries, change-of-control reviews, NDA term comparisons — as firm-wide templates that junior lawyers can run in one click.

The open-source model is central to the pitch. There is no licence fee and no vendor lock-in: firms self-host so privileged documents never leave their perimeter, choose and pay for their own model APIs, extend the workflow library for a practice area, integrate their document management system, and audit how prompts are constructed and how data flows. Newer releases have added an IDE-style workspace, a Word add-in, subagents, web search, memory, a document and template library, and fully local AI via Ollama.

**Pricing & Plans:** Open source with no licence or per-seat fee. Firms self-host or use the cloud sign-up, and pay only for the model API usage they consume — or run it fully locally with Ollama at no model cost.

- **Grounded, citation-backed answers:** The assistant answers strictly from your documents and returns citations pointing to the source page and quote, avoiding hallucinated or dead references.
- **Matter-scoped projects:** Group credit agreements, SPAs, leases and diligence packs into a project so the assistant carries full context across every document and conversation.
- **Tabular review at volume:** Run spreadsheet-style extraction across hundreds of documents in parallel, with every cell verifiably linked back to its source page and text.
- **Reusable firm-wide workflows:** Save proven prompts — CP checklists, credit agreement reviews, change-of-control analyses — as templates any team member can run in one click.
- **Self-hosting and model choice:** Deploy inside your own perimeter, keep privilege and data residency under your control, and plug in the model you prefer, including local AI through Ollama.

**Strengths:** No licence or per-seat fees — you pay only for the model API usage you incur; Self-hostable, so privileged documents and compliance data stay inside your own perimeter; Open codebase and open prompt engineering can be audited, forked and extended for your practice areas; Grounded citations on every extracted cell reduce the risk of hallucinated answers

**Limitations:** Requires real IT effort to self-host, secure and maintain compared with a turnkey SaaS product; You must supply and configure your own model APIs, which shifts model-quality and cost decisions to your team; Cloud sign-up exists, but a partially self-managed setup may not suit firms without technical staff
