Harvey
by Counsel AI Corporation
AI platform for legal and professional services with supervised legal agents
Last reviewed 2026-06-18
Harvey is an AI platform for legal and professional services that combines a legal Assistant, a document workspace (Vault), a knowledge layer, multi-step Workflows and Agents, and Microsoft Office add-ins. It answers legal questions, analyzes and drafts documents, bulk-analyzes large document sets, and runs multi-step legal workflows over legal materials and primary law (via LexisNexis content), with human-in-the-loop checkpoints built in as a core design feature. Harvey targets large law firms (it cites use across a majority of the Am Law 100), in-house legal teams, and professional services, with a strategic alliance with PwC. Despite agentic branding, its workflows are designed around human review at checkpoints rather than end-to-end autonomy, so it operates as a supervised agent. It is among the best-capitalized AI companies, reportedly valued at $11B in a March 2026 round.

Strengths
- +Deep, verifiable enterprise traction (use across a majority of the Am Law 100 and a PwC alliance)
- +Purpose-built legal workflows with LexisNexis primary law and tight Microsoft and iManage integration
- +Extremely well-capitalized, lowering vendor-survival risk
Limitations
- −Hallucination risk is material in a high-stakes domain; even with low reported rates, customers stress validating every output
- −Expensive, opaque, quote-only pricing with seat minimums
- −Autonomy is more supervised than the agent branding implies
Overview
Harvey is an AI platform for legal and professional services, combining an Assistant, a document workspace (Vault), a knowledge layer, multi-step Workflows and Agents, and Microsoft Office add-ins. It is built specifically for legal work.
What it does
Harvey answers legal questions, analyzes and drafts documents, and bulk-analyzes large document sets in Vault. Its Workflows and Agents plan and run multi-step legal tasks with human-in-the-loop checkpoints designed in as a core feature; 2026 additions include ready-made agents, an Agent Builder, and scheduled background runs. Because review checkpoints are central, it operates as a supervised agent rather than an autonomous one.
Integrations & setup
Integrates with iManage, Microsoft Word, Outlook, and SharePoint, Box, and LexisNexis primary-law content, and runs on Microsoft Azure. There is no public developer docs portal.
Pricing
Enterprise, custom-quoted, per-seat annual, with no public prices. Third-party estimates suggest per-user pricing in the low hundreds of dollars per month at large firms, with contracts and seat minimums (reported, not official).
Traction
Harvey is among the best-funded AI companies: it reportedly raised a ~$200M growth round at an $11B valuation in March 2026, co-led by GIC and Sequoia, for roughly $1.1B+ total, with a valuation that climbed steeply through 2025-2026 (reported figures, not audited). It cites use across a majority of the Am Law 100 and a strategic alliance with PwC.
Best for / not for
Best for large law firms, in-house legal teams, and professional services that want purpose-built legal AI with strong integrations. Less suited to buyers needing transparent self-serve pricing or fully autonomous automation.
Alternatives
Hebbia targets document-heavy finance and legal research; Glean is a broader enterprise work assistant.

No. Its workflows and Agents are designed around human-in-the-loop checkpoints rather than end-to-end autonomy, so Harvey operates as a supervised agent; lawyers review and approve its outputs.
What models power Harvey?+
Harvey is built on frontier models and is reported to be multi-model across providers including OpenAI, Anthropic, and Google. The exact current model mix is not published on its site, so this reflects reported positioning.
