Jurata and Silex are two Swiss artificial intelligence solutions designed to support legal professionals in their research, analysis and the drafting of legal documents. Both rely on verifiable legal sources, but they differ in certain features, their technical infrastructure and their integration with the tools used in law firms.
Developed by Jurata AG in Zurich, Jurata Legal Agent in particular makes legal research, drafting and the review of documents easier, directly from a web application or from Microsoft Word.
Silex is also a Swiss legal assistant. It focuses on the research and analysis of federal and cantonal law, while offering features that make it possible to use law firms’ internal documents.
To compare these two platforms, several criteria deserve particular attention: coverage of legal sources, verification of citations, confidentiality of data, possibilities of integration with professional software and features linked to file management.
Jurata: a Swiss legal assistant available in the browser and in Microsoft Word
Founded in Zurich in 2020, Jurata AG initially developed a platform making it possible to put individuals and companies in touch with lawyers. In October 2025, the company launched Jurata Legal Agent, a legal assistant based on artificial intelligence and intended for legal professionals.
According to the company, this solution makes it possible to search for legal information, draft documents and check their content. Its search engine relies in particular on federal law, cantonal legislation, judgments of the Federal Supreme Court and decisions of cantonal courts.
Jurata Legal Agent offers several features intended to make lawyers’ everyday work easier:
- Fast legal research: obtain answers to questions of law from identifiable legal sources.
- Deep Agent mode: carry out more in-depth legal research and analysis.
- Citation checking: automatically compare cited passages with the original documents in order to check their accuracy.
- Document analysis: import contracts, judgments or briefs in order to examine their content.
- Web application: access research and drafting functions directly from a browser.
- Microsoft Word add-in: draft, review and amend documents with tracked changes, in the Pro and Max plans.
- Support for several languages: work in French, German, Italian and English.
According to Jurata, the platform has more than one million legal sources. The various subscription plans differ in particular in usage limits, access to the Word add-in, document-library features and the response times of technical support.
Silex: an artificial intelligence specialised in Swiss law
Silex is a Swiss legal assistant developed to meet the needs of professionals who regularly search for and analyse statutory provisions and court decisions falling under federal and cantonal law.
The platform helps lawyers find relevant sources, organise their reasoning and prepare analyses or draft documents. It thus aims to make certain stages of legal work easier, without replacing the professional’s judgment.
According to its publisher, Silex relies on a corpus of more than 800 000 Swiss legal sources, including in particular statutes, ordinances and court decisions.
The answers generated may be accompanied by references that the lawyer is able to consult in order to check the information presented.
The platform also offers features for document analysis and the processing of internal files, in order to link legal research with the documents used in professional activity.
To discover the platform’s various possibilities, see the page presenting Silex’s features.
Legal research and citation checking: what are the differences?
The reliability of information is an essential criterion when choosing a legal assistant. An answer generated by artificial intelligence can be regarded as sufficiently reliable only if the references on which it rests can be found and checked.
Jurata and Silex both emphasise the possibility of consulting the legal sources used in their answers. They nevertheless take slightly different approaches to verification.
Jurata: automatic checking of citations
Jurata gives a particular place to the control of legal references. According to the publisher, the platform automatically compares cited passages with the original texts.
This feature lets the user distinguish statements directly supported by a source from elements that are only partly confirmed.
The aim is to make the review of generated answers easier and to reduce the risks linked to the use of inaccurate or insufficiently relevant references.
Silex: legal references that can be consulted
Silex emphasises access to Swiss legal sources and the possibility of finding the texts used in an analysis.
According to the company, its answers are accompanied by references enabling professionals to consult the statutory provisions or court decisions concerned.
The lawyer can thus compare the generated answer with the original documents and assess their relevance in the light of the question asked.
Corpora that are not directly comparable
Jurata announces more than one million legal sources, whereas Silex states that it has more than 800 000 Swiss sources.
These figures alone do not, however, make it possible to determine which platform has the documentary coverage best suited to a given practice. The categories of documents counted and the perimeters covered may differ.
Before choosing, it is advisable to check the courts available, the periods covered, the areas of law and the languages in which the documents are accessible.
In both cases, human review remains indispensable. The professional must consult the original references, check their date and legal scope, then determine whether they apply to the file being handled.
To go further into these good practices, see our article on legal analysis assisted by artificial intelligence.
Document analysis and work on legal files
Beyond legal research, Jurata and Silex both make it possible to work on a firm’s internal documents. Their features nevertheless correspond to different uses.
Jurata: analysing and amending documents in Word
Jurata makes it possible to import different types of legal documents, in particular contracts, court decisions and briefs.
Once the files have been uploaded, the user can ask questions about their content, carry out searches and find the relevant passages directly in the documents.
The Microsoft Word add-in is another important feature of the platform. It makes it possible to search for legal information, draft and review texts without leaving the Word environment.
The proposed amendments can be presented with tracked changes, which makes it easier to examine them before they are approved.
In the Pro and Max plans, Jurata also provides an internal library making it possible to keep and reuse document templates.
Silex: analysing files with Silo and specialised agents
Silex offers a feature called Silo, intended for the analysis of law firms’ internal documents.
It in particular makes it possible to examine contracts, notes, files and precedents, then to relate their content to the Swiss legal sources used in the analysis.
The platform also offers several specialised agents to make certain recurring tasks easier:
- Anonymisation: mask the names of the parties and sensitive information by redaction.
- Legal translation: translate documents into French, German, Italian and English.
- Document comparison: identify the differences between two versions of the same text.
- Creation of minutes: turn an audio recording into a structured report.
These features can be particularly useful when preparing documents intended to be sent, checking changes to a contract or handling files that include exhibits drafted in several languages.
Which solution is best suited to documentary work?
Jurata mainly emphasises documented legal research and drafting and review work in Microsoft Word.
Silex offers an approach more oriented towards the use of files, with functions for anonymisation, translation, comparison and the creation of minutes.
Both platforms state that they support French, German, Italian and English. The quality of the results, in particular for legal translations, nevertheless deserves to be assessed on documents representative of your activity.
In every case, generated, translated or amended texts must be carefully reviewed before professional use.
Data hosting, confidentiality and professional secrecy
For law firms, notaries’ offices and other professionals bound by professional secrecy, the confidentiality of data is an essential issue.
The place where documents are stored is, however, only one of the elements to be examined. Account must also be taken of the place where queries are processed by the artificial intelligence models, the processors involved and the conditions of access to confidential information.
Jurata and Silex are two Swiss companies that state that they do not use their clients’ data to train their artificial intelligence models.
Jurata: storage in Switzerland and processing possible in the European Union
According to Jurata, users’ conversations and documents are stored in encrypted form in Switzerland, on Microsoft Azure infrastructure, in the Switzerland North region.
The processing of queries by the artificial intelligence models, also called inference, may nevertheless be carried out by means of Azure services located in Switzerland or in the European Union.
Jurata states that this arrangement does not involve storage of the data with the provider of the model used.
The company also publishes an opinion of the law firm Walder Wyss on questions of professional secrecy and data protection linked to the use of its platform.
Silex: hosting of data in Switzerland with Infomaniak
Silex states that it hosts its clients’ data in Switzerland, with Infomaniak.
According to the publisher, the information is kept separate between the various user organisations and the files transmitted to the platform are not used to train its artificial intelligence models.
This approach may be of interest to professionals who wish to favour Swiss infrastructure for the processing of their files.
Which points should be checked before choosing?
The main announced difference concerns the technical infrastructure and the possible location of query processing.
Jurata relies on Microsoft Azure, with storage in Switzerland and inference that may take place in Switzerland or in the European Union. Silex emphasises hosting of data in Switzerland with Infomaniak.
Before adopting one of these solutions, it is important to check the contractual conditions, the providers actually used, the location of processing and the persons who may have access to the documents.
To go further into these questions, see the page dedicated to Silex security as well as our article on artificial intelligence and data protection.
Integration with the software used in law firms
Integration with professional software can have an important influence on how easy a legal assistant is to use day to day.
A solution accessible directly from the firm’s usual tools in particular makes it possible to limit changes of application and to simplify certain stages of the work.
Jurata: privileged integration with Microsoft Word
Jurata particularly emphasises its Microsoft Word add-in, available in the Pro and Max plans.
This integration enables professionals to carry out research, draft passages and review documents directly from Word, in particular thanks to tracked changes.
The platform also offers single sign-on with Microsoft or Google accounts, in order to simplify access to the service.
Silex: integrations with Swiss practice software
Silex seeks more to integrate its features into the software already used by legal professionals in Switzerland.
The integration of Silex into WinLex and SkyLex in particular makes it possible to carry out legal research directly from these file-management programs.
The partnership between Silex and MCR Solutions pursues a similar approach, with the aim of making the use of legal artificial intelligence easier in existing workflows.
You can also see the announcements relating to the partnership between Silex and EXPERTsuisse and to the adoption of Silex by Bordier & Cie.
The choice will depend in particular on your working environment: professionals who use Microsoft Word intensively may be interested in Jurata’s features, whereas those who work with certain Swiss practice-management programs may examine the integrations offered by Silex.
Jurata and Silex pricing: what are the differences?
Jurata and Silex offer several subscription plans, but their pricing models are organised differently.
Jurata prices
Jurata offers three main plans, billed per user, to which an Enterprise offer quoted on request is added.
According to the price list indicated by the publisher, the monthly prices with annual commitment and billing, excluding VAT, are as follows:
- Entry: 130 CHF per user per month.
- Pro: 160 CHF per user per month.
- Max: 400 CHF per user per month.
If monthly billing is chosen, the announced prices are different:
- Entry: 165 CHF per user per month.
- Pro: 200 CHF per user per month.
- Max: 500 CHF per user per month.
Jurata also offers a seven-day trial period. Companies with particular needs can request an Enterprise offer adapted to their organisation.
Silex prices
Silex presents several monthly plans in Swiss francs, designed for individual users or for teams:
- Solo: 149 CHF per month for one user.
- Team: 490 CHF per month for a team of five users at most.
- Enterprise: 895 CHF per month for a team of ten users at most.
The features of these subscriptions are detailed on Silex’s pricing and solutions pages.
How to compare the prices of the two platforms?
A direct comparison of the amounts displayed is not enough to determine which solution is the more economical.
Jurata applies pricing per user, with features and usage limits that vary according to the plan chosen.
Silex offers an individual subscription as well as plans covering several members of a team.
To compare costs correctly, it is preferable to calculate the annual amount corresponding to the actual number of users and the features required, in particular access to the Word add-in, document-analysis capacity and file-management tools.
The prices mentioned correspond to the information in the source text and must be confirmed with the publishers before any subscription.

Conclusion: should you choose Jurata or Silex?
Jurata and Silex are two Swiss legal assistants that pursue a common aim: to make research, analysis and drafting easier by relying on legal sources that professionals can check.
Unlike a comparison between a general-purpose tool and a specialised solution, the choice between these two platforms rests mainly on their complementary features, their infrastructure and their integration into the working environment.
Jurata Legal Agent stands out in particular for its approach to legal research, its system of automatic citation checking and its integration with Microsoft Word. These features may be of particular interest to professionals who devote a substantial part of their activity to drafting and reviewing documents.
Silex emphasises research in Swiss law combined with the documents in the files. The platform also offers functions for anonymisation, legal translation, version comparison and the creation of minutes, as well as integrations with certain Swiss professional programs.
The conditions of hosting and data processing are also an important criterion. Jurata uses Microsoft Azure infrastructure, with storage in Switzerland and inference possible in the European Union. Silex states that it hosts the data in Switzerland with Infomaniak.
The choice therefore depends first of all on your everyday needs. If you are looking for an assistant closely integrated with Microsoft Word, with automatic citation checking, Jurata deserves to be examined. If you wish to favour research in Swiss law, the use of internal documents and integrations with file-management software, Silex may correspond more closely to your organisation.
In both cases, it is advisable to test the platforms on real legal questions, checking the relevance of the answers, the quality of the references and their suitability for your professional practice.
