Harvey vs. Legora
The two legal AI platforms most large firms shortlist. Both offer agents, bulk document review, legal research and Word and Outlook add-ins; they differ in research content, how you collaborate with clients, and how they reach your DMS. Here's how to pick, and the work neither one does.
Harvey
A legal AI platform for law firms and in-house teams. Harvey lists Agents that execute legal work end to end, Vault for storing and bulk-analyzing documents, Knowledge for legal, regulatory and tax research, Spaces for work shared across organizations, and add-ins for Word and Outlook.
Choose Harvey if
- You want research inside the platform drawn from LexisNexis and other legal databases Harvey lists
- Deals or disputes involve very large document sets (Harvey states up to 100,000 documents per vault)
- You want to build custom agents that encode your playbooks (Agent Builder)
- Your lawyers already work in Microsoft 365 Copilot, where Harvey can be used
Legora
A legal AI platform for firms and in-house teams, built around an Agent that plans, executes and reviews multi-step work. Legora lists Tabular Review, Workflows, Legal Research, Word and Outlook add-ins, Monitors, and Portal, a branded workspace for working with clients.
Choose Legora if
- Tabular review across a document set is the workflow your lawyers use most
- You want a white-label portal to share files and workflows with clients, with no guest license
- Your firm runs NetDocuments and wants its permissions and ethical walls to carry into the AI
- You weight Word-based drafting, redlining and playbook review heavily

The work neither one does
Harvey and Legora are practice tools: they help lawyers research, review and draft. Neither is built to run the firm's operations. The intake form still has to become a matter in the practice management system, the conflicts search still gets assembled by hand, and the signed engagement letter still has to be filed to the right DMS workspace and handed to billing. Those steps repeat every day and sit with operations staff, not lawyers.

Frequently asked questions
What is the difference between Harvey and Legora?
Both are legal AI platforms for law firms and in-house teams, with agents, bulk document review, legal research and Word and Outlook add-ins. Harvey's research module draws on LexisNexis and other legal databases, and Spaces lets organizations work together. Legora centres on its Agent and Tabular Review, and offers Portal, a branded workspace for clients. Neither publishes pricing.
Is Harvey or Legora cheaper?
Neither vendor publishes a price as of September 2026. Both sell through a demo and a tailored contract, so the real comparison is a quote for your seat count and practice groups. Ask each for pilot terms, what counts as a seat, and whether research content, bulk review limits and integrations are included or priced separately.
Do Harvey and Legora work with iManage and NetDocuments?
Yes, both state integrations with each. Harvey's help center documents iManage, NetDocuments, SharePoint and Google Drive integrations. Legora announced a direct API integration with iManage in February 2026 and, in September 2026, an MCP connection to NetDocuments that carries the DMS's access controls and ethical walls into Legora.
Which is better for legal research, Harvey or Legora?
It depends on the content you trust. Harvey Knowledge lists LexisNexis, Wolters Kluwer, SCC Online and other legal databases, with 500+ legal sources across jurisdictions. Legora Legal Research lists Wolters Kluwer and EDGAR for the US plus international partners. Firms that research mainly on Westlaw may also compare CoCounsel Legal. Test both on your own research questions.
Can a firm use Harvey and Legora together?
Some firms pilot both before choosing, and both sell to firms and in-house teams, so a client may use one while its outside counsel uses the other. Running two platforms firmwide doubles training and governance work, so most firms pick one as the primary platform and keep a research tool alongside it.
Does Harvey or Legora automate law firm operations?
Not as their main job. Both are built for legal work: research, review, drafting and agents that produce work product for lawyers. Operations work such as intake, conflicts, matter opening, filing to the DMS and pre-bill review runs across the practice management system, DMS and inbox. That is the work Caddi finds, automates as deterministic code and logs for review.
