Looking for a RechtGPT alternative for a Swiss law firm? CASUS is the stronger choice for teams that want to connect legal research with contract review, dossiers and Microsoft Word. According to the provider, RechtGPT also supports Swiss law and offers a lower entry price for a set number of queries. The deciding factor is whether your priority is answering individual research questions or managing a continuous document workflow.
Quick comparison for Swiss law firms
Both products combine legal research and document features, but they place the emphasis differently. CASUS is designed around continued work on legal documents in the web application and Microsoft Word. RechtGPT foregrounds source-based answers to legal questions and structures its paid plans around monthly query allowances.

What RechtGPT currently offers
RechtGPT is developed by Prime AI GmbH in Austria, but the product is not limited to Austrian law. The provider expressly positions the platform for Austria, Germany, Switzerland, Liechtenstein and European Union law. Users ask legal questions in natural language and receive answers with source references.
The documented feature set also includes document creation using templates, document analysis, questions about documents, OCR processing and use in Microsoft Word. Answers can be exported as Word files. Business and Enterprise subscribers can share their own sources within the subscription. RechtGPT should therefore not be treated as a search engine alone.
For Switzerland, the current RechtGPT product page lists Swiss federal law, cantonal law and case law, along with FINMA circulars, statements and supervisory communications. Listing a source category does not, however, guarantee complete coverage of every field of law or canton.
When CASUS is the better fit
CASUS is strongest when research is regularly followed by work on the document itself. The platform is designed as a web application and Microsoft Word add-in for qualified legal professionals. Drafting, review and editing can therefore take place closer to the version that will ultimately be negotiated, approved or sent.
For larger matters, CASUS dossiers can contain up to 1,000 documents. The full set can be analysed across multiple chats, with references provided. This supports larger document reviews, knowledge management and due diligence. AI-generated results remain suggestions and require final review by a qualified legal professional before use.
RechtGPT also documents Word and document features. The distinction therefore does not rest on a single feature label, but on how research, structured review, dossiers and further editing work together. For Swiss law firms handling contracts and document-heavy matters regularly, that workflow is an important selection criterion.
Testing Swiss legal sources
RechtGPT and CASUS both support Swiss legal sources. A meaningful comparison nevertheless needs to go beyond whether “Swiss law” appears in a product description. The relevant question is whether the legislation, courts, cantons, time periods and citations required for the firm’s actual matters can be found reliably.
The web-based CASUS legal research feature provides access to over 1 million decisions and more than 21,000 federal and cantonal laws. Searchable sources include decisions from the Federal Supreme Court, Federal Administrative Court, Federal Criminal Court and Federal Patent Court, together with cantonal courts. Decision and law counts are reported separately for the connected source corpora. It does not guarantee complete coverage of every field of law or time period.
RechtGPT lists Swiss federal law, cantonal law and case law as well as FINMA materials. Both products should be tested with the same known authorities: a leading Federal Supreme Court decision, a recent judgment, a cantonal question, a provision with a historical version and a specialist regulatory topic.
The assessment should cover answer quality, currency, correct citations, traceable passages and access to the original source. A fast answer without verifiable evidence is not sufficient for professional legal work.
Comparing the Word and document workflows
Both providers mention Microsoft Word. That alone does not show how well a law firm workflow will function. Testing should use an existing document with complex numbering, cross-references, comments and tracked changes. This reveals whether results are merely exported or can be incorporated into the working version in a controlled manner.
With CASUS, a structured Risk Review can be tested on an open document. The same document type should be used with RechtGPT for analysis, follow-up questions, drafting and Word use. A fair comparison measures completion time, coverage, severity of errors, rework and formatting stability.
Dossiers should also be tested beyond a feature checklist. A realistic exercise uses several related documents and checks whether answers remain traceable across the full set and whether cited passages can be verified quickly.
Data security and procurement in Switzerland
RechtGPT states that it uses, among other services, OpenAI models hosted in the Microsoft Azure cloud in the EU. The provider offers a pseudonymisation feature and describes server-side storage of questions, answers and documents as optional. The public page does not specify an Azure region and does not replace a review of the contractual documentation.
CASUS states in its security overview that client-matter content and workspace data are stored in the Google Cloud region in Zurich. AI inference takes place in EU or Swiss regions. According to the approved security information, customer data is not used for model training or fine-tuning, and zero-data-retention arrangements are in place with the LLM providers used by CASUS.
Before selecting either product, Swiss law firms should examine processing locations, data-processing terms, subprocessors, retention and deletion, roles and access, and the treatment of confidential client information. General statements about data protection are a starting point, not the outcome of that review.
Comparing prices and allowances fairly
CASUS offers a 14-day free trial. Standard then costs CHF 145 net per person per month when billed monthly. Annual billing costs CHF 1,440 net per person per year, equivalent to CHF 120 per month. The current pricing page also lists Advanced for organisations on request.
On the same public page that names Switzerland as a supported jurisdiction, RechtGPT displays its prices in euros. Its free test includes seven questions. Starter costs EUR 29 net with 50 queries per person per month, while Business costs EUR 49 with 250 queries. Enterprise costs EUR 29 per person per month, includes 100 queries and requires at least five licences.
These figures are not directly equivalent because they use different currencies and usage models. RechtGPT limits use by queries, whereas the published CASUS Standard pricing does not use the same allowance model. Swiss purchasers should also confirm the billing currency, tax treatment and contractual offer before making a decision.
Running a pilot with Swiss matters
A useful pilot covers three to five recurring tasks: a question of Swiss law with a known citation, a cantonal-law question, analysis of a scanned document, review of an existing contract and an amendment to a complex Word file.
For each task, record completion time, coverage, source quality, severity of errors, rework and usability. For RechtGPT, also record how many queries a typical matter consumes. This makes it possible to assess whether the selected plan matches actual monthly demand.
The CASUS pilot should test the complete sequence of research, document review, dossiers and Word editing. RechtGPT provides the comparison for a more query-based research workflow and lower entry price.
Conclusion
For Swiss law firms that want to combine legal research, contract review, dossiers and Microsoft Word in one continuous workflow, CASUS is the stronger choice in this comparison. Its document-centred workflow, Zurich data region for client-matter and workspace content, and 14-day free trial support that conclusion.
RechtGPT remains relevant when research across several jurisdictions and a limited number of individual queries are the main priorities. To evaluate the broader CASUS workflow, firms can try CASUS free for 14 days or first review the Word add-in.
