Legora vs Spellbook: 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.

Spellbook is a contract AI suite made by Dialog Enterprises Inc., a Canada-based company that operates under the Spellbook name. The company says its first generative contract review tool launched in 2022, and its current website says more than 5,000 legal teams use the product. Its October 2025 funding announcement reported 4,000 law firms and in-house legal teams in 80 countries, while the current site reports more than 5,000 teams. The company’s product focus is transactional work: drafting agreements, reviewing terms, applying redlines, and keeping positions consistent across a deal. Spellbook is therefore aimed at commercial legal teams rather than users seeking a general legal chatbot or a dedicated case-law research database.

A normal Spellbook workflow starts with a contract or intake request and keeps the lawyer in the review loop. The product can pull contracts from email and Slack, run a first-pass review against team standards, draft clauses or full agreements, and produce tracked redlines in Word. Review, Draft, Ask, Benchmarks, and Playbooks cover the Word add-in workflow. Playbooks turn recurring instructions into reusable review checklists, while Library and Repository features make precedents and signed agreements searchable. Associate is a multi-document agent for transactional matters that works under attorney oversight. Spellbook also lists integrations with Google Docs, OneDrive, Dropbox, SharePoint, Google Drive, and iManage. The lawyer remains responsible for checking suggested language and deciding which changes to accept.

Spellbook’s contract focus is useful for lawyers who work in Word and apply repeatable review standards, but it limits the product’s role. Harvey overlaps on AI-assisted legal drafting and analysis, while Ironclad overlaps more closely on contract operations, repository management, and lifecycle workflows. LawGeex is another contract-review alternative. Spellbook publishes no dollar price, requires attorney oversight, and does not present itself as a substitute for legal judgment. Its public pages also do not establish a self-hosted deployment or a public developer API. Choose Spellbook if your team drafts and negotiates commercial contracts and wants Word-based review with reusable playbooks. Choose a broader legal research or contract-lifecycle product when those functions matter more than Word-native review.
