A Harvey alternative should match the work your legal team actually performs. CASUS is our recommendation for DACH-focused teams that want local legal research, document analysis, drafting, and Microsoft Word with public pricing. Harvey is the stronger candidate for global enterprises prioritising broad integrations, agents, and governed international rollout.
CASUS vs Harvey at a glance
Purchase question | CASUS | Harvey |
|---|---|---|
Core fit | DACH legal research plus document and Word workflows | Global enterprise legal AI platform |
Legal research | Verified CASUS scope for Switzerland, Germany, and Austria | More than 500 regional knowledge sources stated; exact contracted country coverage must be checked |
Microsoft workflow | Word add-in for drafting, reviewing, and editing | Word and Outlook plus SharePoint and other integrations |
Multi-document work | Dossiers with up to 1,000 documents; AI Data Room for larger document collections | Vault for comparable matter-based, multi-document analysis; category-level parity |
Standard pricing | Public CHF and EUR prices plus a 14-day trial; clearly below the researched Harvey estimates | Quote only; three third-party sources put a regular base seat around USD 1,000–1,200 per month |

Model training | Customer data is not used for training or fine-tuning | Inputs, outputs, and uploaded documents are not used to train underlying models |
The table is a procurement map, not a universal quality score. Plan, contract, data package, optional features, and customer configuration can change the practical result.
The short verdict
Choose CASUS when most matters are governed by Swiss, German, or Austrian law and your team wants a transparent route from research to reviewed documents. CASUS publishes standard prices, can be tested for 14 days, and combines a web application with a Word add-in. Its strongest differentiator is the documented country-specific research scope rather than a generic global-source headline.
Choose Harvey when a large organisation needs an enterprise AI layer across offices, repositories, and work types. Harvey describes Agents, Vault, Workflows, Knowledge, and integrations with Word, Outlook, iManage, NetDocuments, SharePoint, and Google Drive. That breadth can matter more than self-service procurement for an international firm.
Neither choice should be made from a feature checklist alone. Both products support Word, both publish regional data-residency options relevant to Europe, and both state that customer content is not used to train underlying models. CASUS Dossiers and AI Data Room cover the same core multi-document category as Harvey Vault, so that capability is even at this level of comparison. The meaningful questions are source depth, output quality, regional configuration, administration, rollout effort, and total contract cost.
Legal research: explicit DACH scope or a broad ecosystem
CASUS Legal Research makes its local scope concrete. In Switzerland, the web research product provides access to more than 660,000 court decisions together with federal and cantonal law. Supported court filters include the Federal Supreme Court, Federal Administrative Court, Federal Criminal Court, Federal Patent Court, and cantonal courts.
In Germany, around 500,000 case-law entries are searchable. German legislation is not part of the current CASUS search scope, which is an important limitation for a fair evaluation. In Austria, around 1.5 million indexed entries from legislation and case law are searchable. These figures describe indexed entries, not guaranteed unique documents or complete coverage.
Harvey states that its ecosystem includes more than 500 regional knowledge sources. Its public material also names selected regional partners and content. That establishes a broad ecosystem, but it does not show the exact Swiss, German, or Austrian sources, licences, update cadence, and link behaviour included in a particular customer contract.
For DACH research, CASUS therefore offers the clearer public purchasing signal. Harvey may provide the required sources as well, but buyers should ask for a contract-level list and test the exact courts, statutes, commentary, and practice areas they need.
Word, document review, and multi-document work
CASUS is a web application with a Microsoft Word add-in for trained legal professionals. Lawyers can draft, review, and edit documents in Word. The CASUS AI Data Room uses Dossiers for matter-based analysis: a Dossier can contain up to 1,000 documents and return references to relevant passages.
Harvey is not a browser-only assistant. Its current ecosystem includes Word and Outlook, while Vault, Workflows, and enterprise integrations connect the platform to wider knowledge and document systems. For organisations already operating iManage, NetDocuments, SharePoint, or Google Drive across many offices, that integration layer can be decisive.
For the core job of analysing a connected document set, CASUS Dossiers and AI Data Room are comparable with Harvey Vault. We therefore score multi-document analysis as even, not as a Harvey advantage. The products still differ in limits, administration, surrounding integrations, and the way results are cited, so those details belong in the pilot.
The right test is practical: give both products the same complex Word document, including numbering, comments, cross-references, and tracked changes. Then compare the quality of the legal suggestion and the work required to insert, verify, and format it.
Security and data residency
CASUS states that client-matter content and workspace data are stored in Google Cloud’s Zurich region. AI inference runs in EU or Swiss regions, and CASUS and its model providers do not use customer data for model training or fine-tuning.
Harvey’s security page says the platform is hosted on Azure and that customers can choose data residency in an EU region or Switzerland. Harvey also states that inputs, outputs, and uploaded documents are not used to train underlying models and that model providers are contractually bound to zero data retention.
The old claim that Harvey necessarily sends European customer data to the United States is therefore not a sound comparison. Procurement teams should instead verify the selected region, optional functions, subprocessors, support access, retention, and contractual terms for their actual configuration. A region label alone does not complete a professional-secrecy or transfer assessment.
Pricing and procurement
CASUS publishes its standard prices. In Switzerland, the price is CHF 145 per user per month or CHF 1,440 per year. In euro markets, it is EUR 155 per month or EUR 1,560 per year. A 14-day trial provides a self-service route to test the product. Advanced organisation features are quoted separately.
On the official Harvey pages reviewed for this comparison, no general numerical standard price was available. Three clearly marked third-party sources nevertheless converge on a regular base estimate around USD 1,000–1,200 per user per month: the Metronome Pricing Index lists USD 12,000–14,400 per seat per year, Sacra estimates USD 1,200 per lawyer per month, and an anonymous 2026 buyer report describes an initial USD 1,200 monthly quote. That buyer also reports a reduced tier around USD 399 and USD 2,400 with Lexis, showing how strongly scope can change the price.
These are research estimates, not Harvey list prices, and Harvey has not confirmed them. Against that reported regular-base range, CASUS at CHF 145 or EUR 155 per month is clearly and substantially cheaper. An individual Harvey offer could differ by seat count, contract term, content, integrations, region, and negotiation.
Ask both suppliers for a complete annual scenario: licences, required legal content, implementation, integrations, administration, training, support, usage limits, and renewal rules. Public entry pricing and enterprise total cost are different questions.
A six-step pilot for a defensible decision
Use the same three to five representative matters in both products.
Include one known-answer local research question and verify every cited passage.
Review one Dossier or Vault task with the same document set and scoring rubric.
Test one difficult Word document for drafting, review, tracked changes, and formatting preservation.
Record the configured storage and processing regions, subprocessors, permissions, and audit controls.
Compare time to a review-ready result and total annual cost under realistic use.
Score serious errors separately from minor omissions. Legal AI outputs remain suggestions and need review by a legally trained person. A polished answer is not evidence that the underlying proposition or citation is correct.
Final recommendation
CASUS is the better Harvey alternative for DACH firms and legal departments that want explicit local research coverage, document analysis, Word, public standard pricing, and a trial in one product. The advantage is strongest when the team must move regularly between a local authority, a matter file, and a final Word document.
Harvey remains a strong option for large international organisations that value enterprise agents, Outlook, DMS integrations, and a centrally governed rollout across many teams. Its exact regional knowledge package and commercial scope should be demonstrated rather than assumed.

Frequently asked questions
Is CASUS a credible Harvey alternative?
Yes. CASUS is particularly relevant for DACH-focused teams that need local legal research, document analysis, drafting, and Word in one workflow. Harvey has the broader enterprise integration ecosystem, so the better choice depends on jurisdiction, repositories, governance, and rollout scale.
Does Harvey have a Microsoft Word integration?
Yes. Harvey supports work in Microsoft Word and Outlook. Its ecosystem also includes integrations such as iManage, NetDocuments, SharePoint, and Google Drive. A pilot should still test the exact Word actions, formatting, permissions, and plan availability required by the team.
Does Harvey offer EU or Swiss data residency?
Yes. Harvey states that customers can choose data residency in an EU region or Switzerland. Buyers should verify their selected configuration, optional functions, subprocessors, support access, and contract rather than relying on the region label alone.
How much does Harvey cost compared with CASUS?
CASUS publishes standard CHF and EUR prices and offers a 14-day trial. Harvey publishes no general list price, while three third-party sources put the regular base estimate around USD 1,000–1,200 per user per month. CASUS is therefore clearly cheaper against the researched range, although a final comparison still requires equivalent licence, content, integration, support, and usage scopes.
Which product is better for Swiss, German, or Austrian legal research?
CASUS publishes a concrete research scope for all three markets. Harvey describes more than 500 regional knowledge sources, but buyers should request the exact contracted country list and test required courts, statutes, commentary, update cadence, and source links.
Can CASUS or Harvey replace a lawyer?
No. Both products assist legal work, but generated output must be checked against the source material and the facts of the matter. CASUS explicitly treats outputs as drafts or suggestions that require review by a legally trained person.
