# Harvey: reviews and analysis > The reference AI assistant in big law firms: research, contracts and legal workflows end to end. - Canonical: https://serchai.com/en/reviews/harvey/ - Site: Serchai (https://serchai.com) — AI tools comparator - Language: en - Updated: 2026-07-27 --- ## Verdict Harvey is the AI assistant with the deepest reach in the big-law segment: more than seventy AmLaw 100 firms and an increasingly deep alliance with Microsoft, which in July 2026 added its own internal legal department as a client. It covers research, contract analysis, mass document review and running workflows with agents, with native integration into Word, SharePoint and Microsoft 365 Copilot. It publishes no rate at all: everything goes through a sales demo and case-by-case contracts, built for firms with a serious software budget, not for a single lawyer who wants to try it and decide. **Best for:** Large firms and corporate legal departments with a software budget and enough volume to justify an enterprise contract. **Rating:** 3.8/5 ## Pros - Validated adoption in the toughest segment: more than seventy AmLaw 100 firms - Deep integration with the Microsoft ecosystem (365 Copilot, Word, Azure) - Fast product pace, with month-by-month documented updates ## Cons - Publishes no rates: the price only shows up after a sales demo - Aimed almost exclusively at large firms and corporate legal departments ## Key facts - Price: Price on request: no public rate card, sold via demo - Free trial: No - Platforms: Web, iOS, Android - Categories: [Productivity](https://serchai.com/en/best-ai/productivity/), [Writing & reading](https://serchai.com/en/best-ai/writing/) - Official website: https://harvey.ai ## What the internet says (agentic sweep) The week is defined by the Microsoft alliance, which has now reached the company's own internal legal department.

It covers research, contract analysis, mass document review and running workflows with agents, with deep integration into the Microsoft ecosystem. In July 2026 Microsoft's own internal legal department adopted it, the clearest sign yet of how far the alliance between the two companies goes. Its drawback is the same as every other serious legal assistant: it publishes no rates. ## What Harvey is and how it works Harvey launched in 2022, founded by Winston Weinberg, a former O'Melveny litigator, and has become the name cited as the reference whenever AI in big law firms comes up. It is not a single product but a set of modules: **Harvey Agents** to run legal work end to end, **Vault** to store and analyse large volumes of documents, **Knowledge** for legal, regulatory and tax research, **Contract Intelligence** to speed up contract analysis and negotiation, **Shared Spaces** to collaborate securely across organisations, and **Command Center** to measure internal adoption. The piece that most defines its market position is the Microsoft relationship. Harvey integrates into Microsoft 365 Copilot, Word, SharePoint and Azure, and in July 2026 that alliance went a step further: Microsoft's own internal legal department (CELA) started using Harvey for its compliance and advisory operations, as confirmed both by Harvey's official blog and by specialist legaltech press. ## What using it is like day to day What sets Harvey apart from a general assistant is the sheer number of firms that have put it into production: more than seventy AmLaw 100 firms, the most demanding segment with the least room for error in the entire legal sector. That adoption is not a loose marketing figure. It can be traced in the firms' own announcements and in the steady coverage from outlets like LawNext or Artificial Lawyer. The update pace also shows. The monthly product newsletter ("The Brief") regularly documents things like new language models, expansion to Android and iOS mobile apps, and additional security controls in Vault, which points to sustained investment rather than a launch left to sit still. ## Pricing and plans Harvey publishes no rate at all. The `/pricing` page on its site returns a straight error, and there is no figure, tier or per-user price anywhere on the site. The only way in is requesting a sales demo. Any estimate circulating on forums or third-party blogs about what Harvey costs does not come from an official source, so none is recorded here: writing one down would mean inventing it. What can be stated with the sources available is that the sales model is an annual, case-by-case negotiated contract with seat minimums, built for a firm with a corporate software budget. ## Who it is for (and who it is not for) It fits large firms and corporate legal departments with enough volume to justify an enterprise contract and a team dedicated to managing the rollout. The Microsoft 365 integration makes it especially comfortable for organisations already living inside that ecosystem. It does not fit a small firm or a solo lawyer who wants to know the price before talking to a salesperson. Nor is it the most natural pick for a Spanish-speaking reader who needs coverage of local law: its origin and client base are centred on the common-law market. ## Alternatives to Harvey [Legora](https://serchai.com/en/reviews/legora/) is its most direct European competitor, with the same demo-led sales model but more presence at firms on the continent. [vLex Vincent AI](https://serchai.com/en/reviews/vlex-vincent/) solves a different, complementary problem: its edge is not running workflows with agents, but an in-house document base with real depth in Spanish. ## Verdict Harvey is, today, the name a large firm mentions first when talking about legal AI, and that position holds up on verifiable adoption in the sector's most demanding segment and a Microsoft alliance that keeps growing. It is not a product built for everyone: it is large-firm infrastructure, with the price that implies and no public figure confirming it. For anyone with the volume and the budget, the question of whether Harvey works is already answered by who uses it. The real question is how much it will cost, and only a salesperson can answer that. ## Alternatives - [Legora](https://serchai.com/en/reviews/legora/) — Agentic operating system for European firms: research, drafting and contract review in Word and Outlook.
