The comparison
| Tool | Main job | Who it's built for | Published pricing | What we couldn't verify |
|---|---|---|---|---|
| Harvey | "AI software for legal and professional services": Contract Intelligence, Vault, agents, research | Law firms (including mid-size) and in-house teams | None; "Request a Demo" | Review accuracy, which model providers it uses, deployment cost |
| Hebbia | "AI built for the rigor of finance": Matrix (analysis across documents) and Max; legal page covers due diligence, contract review, credit agreements | Investors, bankers, lawyers, consultants and corporate teams | None; "Request a demo" | Contract review depth, legal customer use, data retention |
Who each is for
Harvey. A legal team that wants contract review, document storage and research on one platform. Harvey says Contract Intelligence helps "accelerate routine reviews, sharpen negotiations, and surface portfolio-wide insights," and that Vault organizes "thousands of documents" and extracts insights with a query. Thin spots: no price, and no accuracy data on the pages we read. See Harvey, the Harvey review and Harvey pricing.
Hebbia. A deal team that wants to analyze many documents across transactions. Its legal page says it can "speed up due diligence and contract review" and lists credit agreements, capital markets filings and fund documents. It shows firm logos but does not say what they do with it. Thin spots: the homepage is finance-first, and it states no retention terms. See our Hebbia profile.
Pricing, as shown on October 21, 2026
Neither the Harvey homepage nor the Hebbia pages we read show a price. Both direct you to request a demo. We do not estimate prices; ask each for a written quote for your user count and document volume.
Security claims, as each vendor states them
Harvey's security page lists SOC 2 Type II, ISO 27001, ISO 27701, ISO 42001 and AIUC-1, says it "never trains on customer data," and says it requires zero data retention by model providers. Hebbia's security page lists SOC 2 Type 2, ISO 27001:2022 and ISO/IEC 42001:2023, GDPR and CCPA, says documents, prompts and outputs are never used to train its models or those of its model providers, and says it runs across the US and EU with a dedicated tenant if needed. These are vendor claims; certificate scope and audit dates are not on the pages. See Harvey security and data privacy.
What we couldn't verify
- Contract review accuracy of either product.
- Pricing, minimums and contract terms.
- Scope and dates of the security certifications.
- Hebbia's data retention terms and Harvey's retention periods (Harvey says customers control retention but gives no periods).
- What the law-firm logos on Hebbia's page use it for.
How we'd test the two in a week
- Pick 20 executed contracts of one type and 5 questions you already know the answers to.
- Run the same contracts and questions through both demos, with your own reviewer present.
- Score answers against your known answers, and check that each cites the source clause.
- Ask each for its data terms and the scope of its certificates in writing.
- Compare the quotes for the same user count and volume.

Questions and answers
How does Hebbia compare to Harvey for contract review?
Harvey describes a legal-first platform with Contract Intelligence and Vault; Hebbia describes a finance-first platform whose legal page covers contract review and diligence. We have not tested either, so we cannot rank accuracy.
Is Hebbia a legal AI tool?
It has a legal page, but its homepage headline is "AI built for the rigor of finance" and names investors, bankers, lawyers, consultants and corporate teams as users.
Does Harvey or Hebbia publish pricing?
No. Both direct you to request a demo.
Which is safer for confidential documents?
Both state SOC 2 and ISO 27001 and say they do not train on customer data. These are vendor claims; ask for the reports and data terms.
Who should trial Hebbia instead of Harvey?
A team doing diligence across large deal document sets, such as a banking or finance practice. A team centered on contract work, research and drafting fits Harvey's description better.
