Legora vs Luminance: pricing, features and which to choose

Legora is the legal AI company formerly called Leya, founded in Stockholm in 2023 and launched as a platform in October 2024. Its latest financing is a $550 million Series E announced on October 21, 2026, at an $8.8 billion post-money valuation, replacing the October 2025 Series C as the latest round. The company reports more than 1,000 employees across 18 offices and use by over 140,000 legal professionals at more than 2,400 law firms and in-house teams across over 80 markets. It previously reported smaller 2025 figures, including more than 400 firms and legal teams in over 40 markets. Those figures are company reports, not independent usage audits.

Legora supports research, drafting, document review, and large-scale extraction. Lawyers can work through the browser, desktop app, Word and Outlook add-ins, or connected document systems. Tabular Review places documents in rows and requested facts, clauses, dates, or risks in columns, supporting diligence and portfolio review. Editor supports drafting, while Legal Research returns answers with structured citations. Workflows and Agent handle multi-step research, analysis, and drafting. The aOS connects interfaces, data sources, legal capabilities, context, and governance. Buyers should test citation quality, source coverage, jurisdictional fit, and the amount of lawyer review required on representative matters before expanding access.

Legora’s main weakness is procurement friction: pricing is private, there is no public trial, and consumption billing can complicate forecasting. Harvey is the closest broad competitor, also serving law firms and in-house teams with research, drafting, review, and workflow automation. Spellbook is narrower and centers on Microsoft Word contract work, while Luminance focuses more heavily on contract intelligence, analysis, and negotiation. Thomson Reuters CoCounsel combines legal research and drafting with Thomson Reuters content and professional tools. Legora suits teams handling multilingual, high-volume review and complex matters that can support enterprise procurement. Smaller teams seeking transparent monthly pricing should compare self-serve products first. Security certifications and data-use claims still require contractual review.

Luminance is a Cambridge-born legal technology company founded in 2015 and launched commercially in 2016. Its platform applies specialist artificial intelligence to contracts and related legal work for enterprise legal departments, law firms, procurement teams, sales groups, finance functions, and compliance staff. The company’s About page reports more than 1,000 enterprise customers across over 70 countries and more than 220 million legally verified documents informing its AI. Its February 2025 funding announcement reported a $75 million Series C led by Point72 Private Investments, bringing total funding to $165 million. Luminance is designed for organisations managing substantial agreement portfolios, rather than consumers seeking an inexpensive general legal chatbot or casual question answering service.

A typical workflow begins when users import agreements from local files or connected repositories. The Repository helps teams organise documents, search across clauses, extract structured terms, identify risks, and examine obligations. Negotiation compares proposed language with an organisation’s preferred positions, supports redlining, and records relevant context. Other workflows address drafting, post-execution monitoring, compliance, investigation, and collaboration. Luminance also markets Lumi, specialist agents, and Lumi Go, which allows a customer to send a draft agreement to a counterparty for AI-assisted negotiation. The platform supports work beyond Legal by presenting contractual information to procurement, sales, finance, and executive teams. Human review remains necessary for legal judgments, business decisions, approvals, and final contract execution.

Luminance’s enterprise focus, negotiated procurement, and dependence on contract context make it a poor fit for casual legal questions or teams requiring transparent self-serve pricing. CoCounsel and Lexis+ with Protégé are broader comparisons for legal research, analysis, drafting, and question answering connected to large legal information services. Legora is a closer workspace competitor for law firms and in-house legal teams seeking integrated drafting, research, collaboration, and agent workflows. Luminance is strongest when the central problem is a large corporate contract portfolio spanning review, negotiation, repository analysis, and obligations. Choose it when governance, portfolio intelligence, and controlled model selection matter more than a public price, an open developer platform, or a general legal research assistant.
