Harvey vs Kira: pricing, features and which to choose

Harvey is an enterprise legal software company founded in 2022 by Winston Weinberg and Gabe Pereyra, according to TechCrunch’s account of its origin. Its March 2026 announcement said more than 100,000 lawyers across 1,300 organizations used Harvey, while the homepage later reported 3,500-plus legal organizations, 200,000-plus professionals, and use in more than 85 countries. In September 2026, Harvey announced $550 million in funding at a $15.5 billion valuation. The company’s March announcement said it had raised more than $1 billion in total funding. Harvey remains an active legal software company. Harvey targets law firms and corporate legal departments through an enterprise sales process. Its products combine legal assistance with shared document workspaces, rather than offering a consumer-facing legal-advice subscription.

Harvey organizes work across agents, Spaces, Vault, contract intelligence, research, and Command Center. A typical engagement starts with a user uploading documents or working in a connected workspace, then asking Harvey to analyze, compare, summarize, draft, or extract information. Vault is designed for querying large document collections, while agents route tasks across complex legal work. Shared Spaces bring firms, clients, and co-counsel into one workspace with governance and ethical-wall controls. Command Center gives administrators visibility into usage across teams, practice groups, and offices. Teams can keep reference documents in Vault and use workflows to repeat a structured task. The platform also offers a Word add-in, reducing the need to move contract drafting entirely into a separate interface.

The company's security page says customer data is not used to train models. Buyers still need to review retention, access controls, and deployment terms against their own confidentiality obligations before putting client documents into production. Harvey’s clearest advantages are its breadth of legal workspaces, model selection, custom agents, document collections, and administrative controls. Its main tradeoffs are opaque pricing, enterprise deployment requirements, reliance on external model providers, and the need for lawyers to check generated work. Clio Duo, Spellbook, LexisNexis Protégé, CoCounsel, Luminance, and Ironclad AI overlap with parts of Harvey’s legal-assistance category, although their product scopes differ. Harvey is the stronger fit for larger firms and in-house departments that need shared legal workspaces, custom agents, regional processing, and governance. Smaller teams should first confirm pricing, implementation effort, and required controls.

Kira is Litera's contract intelligence product for high-volume legal review and due diligence. Kira Systems was founded in Toronto in 2011, and Litera agreed to acquire it in August 2021 for an undisclosed sum. The transaction made Kira part of Litera's Transaction Management platform, while Kira's corporate-market technology became Zuva. Kira's current product supports law firms and legal teams working across M&A, real estate, banking, finance, tax, and IP matters. Litera's review page lists more than 1,400 lawyer-trained extraction fields, and its 2026 product announcement says the underlying proprietary models were trained on more than 1 million legal contracts. Litera presents Kira as a specialist product for high-stakes contract analysis, not a general-purpose legal chatbot.

A Kira workflow starts with a project and a contract set. The system extracts provisions, answers deal-specific questions, and links answers back to source contracts so reviewers can check the result in context. Teams work in collaborative review grids, compare clauses, flag risks, and export findings into reports. Users can query a contract set in natural language or create custom fields for questions specific to a deal. Litera lists pre-built fields for common review work and supports customer-trained fields through its training module. Kira covers M&A, real estate, banking, and finance reviews, while the broader Litera workflow connects Kira with Lito. Litera says Lito can produce a plain-language diligence report from Kira extraction data and is included in Kira subscriptions.

Kira is a focused contract review system, and that focus limits its role. Compared with Clio Manage AI, Kira overlaps on legal work automation but is aimed at structured contract extraction rather than practice management. Compared with Spellbook, Kira is aimed at large diligence projects and review grids, while Spellbook overlaps in contract review and drafting. Compared with Harvey, Kira has a narrower contract intelligence job, with source-linked extraction and custom provision fields. The main buying constraints are custom pricing, document and storage terms, implementation, and Litera ownership. Kira fits law firms and legal teams that review enough contracts to justify repeatable provision-level analysis, collaborative grids, governance controls, and a formal procurement process.
