Pandektes and Silex are two artificial intelligence solutions for legal professionals. Both make legal research, document analysis and drafting easier. They differ, however, in their origin, their approach to Swiss law and the way they host data.
Developed in Denmark, Pandektes is a European legal assistant that has extended its activities to Switzerland. It makes it possible to carry out research based on legal sources, analyse files and assist with the drafting of documents. According to its publisher, client data is hosted and processed in the European Union.
Silex is a Swiss solution designed specifically for research and analysis of federal and cantonal law. It relies on verifiable legal sources and favours hosting of data in Switzerland.
To choose between these two platforms, several criteria deserve to be examined: coverage of Swiss legal sources, the languages available, document-analysis features, confidentiality of data and the possibilities of integration with the software used by law firms.
Pandektes: a European legal AI now available in Switzerland
Founded in Copenhagen in 2023, Pandektes is a Danish company specialised in artificial intelligence applied to the law. After expanding in Denmark and then in Germany, it announced its arrival on the Swiss market in 2026.
Its platform supports professionals in their legal research, the analysis of files and the drafting of documents. According to the company, the answers generated rest on identifiable sources and point back to the documents used, so that lawyers can check the information proposed.
Pandektes in particular offers the following features:
- Legal research assistant: obtain answers accompanied by references to the sources used.
- Documentary database: search legislative texts, court decisions and administrative decisions.
- Projects workspace: gather the documents in a file, analyse them and build an internal document library.
- Redact function: anonymise documents by masking personal data and sensitive information.
- Microsoft Word add-in: work directly on legal documents and make their review easier.
- iOS app and API: access certain features from a mobile device or integrate them into other tools.
According to Pandektes, more than 500 organisations already use its solution, including law firms and public authorities.
Silex: an artificial intelligence specialised in Swiss law
Silex is a Swiss legal assistant developed to meet the needs of professionals working with federal law and cantonal legislation.
The platform makes it easier to search for statutory provisions, analyse court decisions and prepare legal documents. It also helps users structure their reasoning and find the references needed to support their analyses.
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 aim is to let professionals access the relevant information quickly while retaining the possibility of consulting and checking the original sources.
As with any legal artificial intelligence tool, the professional remains responsible for interpreting the results and validating the documents produced.
To discover the platform’s various features, see the page presenting the Silex product.
Legal research: which sources are available?
The quality of a legal assistant depends in particular on its ability to provide reliable answers, based on relevant and verifiable sources.
Pandektes and Silex both give an important place to the traceability of the information used in their answers. Their documentary coverage is not, however, presented in the same way.
According to Pandektes, Swiss professionals can search and analyse more than 500 000 Swiss court decisions. The company states that its database covers the Swiss court system and continues to grow.
For its part, Silex announces a corpus of more than 800 000 Swiss legal sources, including legislative texts and court decisions. The assistant’s answers are accompanied by references that users can consult.
It is important to note that these two figures are not directly comparable. Pandektes’ figure concerns Swiss court decisions, whereas Silex’s figure covers a broader set of legal sources.
Before choosing a solution, it is therefore preferable to check the actual coverage of the courts, periods, areas of law and languages that correspond to your professional activity.
To go further into this question, see our article on legal analysis assisted by artificial intelligence.
The specific features of Swiss law: an essential criterion
The Swiss legal system has several particularities that professionals must take into account when they use an assistant based on artificial intelligence.
It rests in particular on the relationship between federal law and cantonal legislation. Added to this are decisions of the Federal Supreme Court, the case law of cantonal authorities and the use of several languages in legal practice.
A search may thus require consulting documents in French, German or Italian, while distinguishing the rules that apply according to the canton or the court concerned.
Silex was designed around these particularities of Swiss law. Pandektes, initially developed for other European markets, has gradually extended its documentary coverage to Switzerland.
In both cases, the professional must make sure that the references proposed actually correspond to the legal framework of the file, in particular as regards the applicable legislation, the court, the date and the language of the sources.
Document analysis and management of legal files
Beyond legal research, Pandektes and Silex offer features that make it possible to work directly on a firm’s internal documents.
Pandektes has a Projects workspace in which users can import exhibits, ask questions about their content and organise document libraries.
Its Redact feature makes it possible to anonymise documents by masking personal data, including when a large number of files must be processed.
The Microsoft Word add-in, for its part, makes the review of legal documents easier. According to the publisher, it in particular makes it possible to propose changes with tracked changes and to insert footnotes referring to the sources used.
Silex, for its part, offers Silo, a feature that makes it possible to analyse the firm’s contracts, notes, files and internal precedents, then to relate them to the relevant Swiss legal sources.
The platform also provides several specialised agents to automate certain everyday tasks:
- Document anonymisation: mask the names of the parties and sensitive information by redaction.
- Legal translation: translate documents into French, German, Italian and English.
- Version comparison: identify the changes made between two versions of a document.
- Creation of minutes: turn an audio recording into a structured report.
The translation functions can in particular make it easier to handle files containing documents drafted in several national languages.
As for anonymisation and document comparison, they are particularly useful when preparing, checking or transmitting legal exhibits.
Whatever platform is used, generated or amended documents must be reviewed before professional use. Artificial intelligence tools are an aid to legal work, but they do not replace the lawyer’s check.
Data hosting, confidentiality and professional secrecy
The confidentiality of information is a major issue for law firms, notaries’ offices and other professionals bound by professional secrecy.
When a file contains personal data, sensitive information or confidential documents, it is essential to know the conditions under which these elements are hosted, processed and possibly accessible to external providers.
Pandektes: hosting in the European Union
According to Pandektes, its clients’ data is stored and processed exclusively in the European Union.
The company states that it holds ISO 27001:2022 certification, relating to information security management. It also states that its clients’ data is not used to train or improve its artificial intelligence models.
For the German market, Pandektes also highlights its compliance with the BRAO, the rules governing in particular the legal profession in Germany.
As Switzerland is not part of the European Union, hosting in the EU should be distinguished from hosting on Swiss territory.
Processing of data in the European Union may be compatible with Swiss data-protection legislation. It nevertheless requires a check of the applicable duties, in particular as regards confidentiality and professional secrecy.
Silex: hosting of data in Switzerland
Silex states that it hosts its users’ data in Switzerland, with Infomaniak.
According to the company, the data is kept separate between the various client organisations and the files transmitted to the platform are not used to train its artificial intelligence models.
This location may be an important criterion for professionals who wish to favour processing of their data on Swiss territory.
In every case, it remains advisable to check the contractual conditions, the security measures, any processors and the arrangements for processing and accessing confidential information.
To find out more, see the page dedicated to Silex security and our article on artificial intelligence and data protection.
Integration with law firms’ software
The possibility of integrating a legal assistant into the software already used is another important criterion. Good integration makes it possible to limit changes of environment and to simplify certain everyday tasks.
Pandektes in particular offers a Microsoft Word add-in, an iOS app and an API making it possible to connect certain features to other IT systems.
This approach may interest professionals who regularly work in Word or wish to integrate artificial intelligence functions into their own tools.
Silex, for its part, favours integrations with the practice software used by Swiss professionals.
The integration of Silex into WinLex and SkyLex in particular makes it possible to launch legal research from the file-management software, without systematically having to switch from one application to another.
The partnership between Silex and MCR Solutions pursues a similar aim by making it easier to integrate AI-assisted legal research into existing workflows.
You can also see the announcements on the partnership between Silex and EXPERTsuisse and on the adoption of Silex by Bordier & Cie.
