Legora or Silex: which tool should you choose for Swiss legal work? The two solutions meet different needs.
Legora is an international platform designed to automate complex legal processes in large law firms. Silex focuses on legal research and analysis in Swiss law, with verifiable sources and data hosted in Switzerland.
The choice depends mainly on your automation needs, the quality of Swiss legal sources and your confidentiality requirements.
Legora: automating complex legal processes
Legora presents itself as an agentic platform for legal work. It lets users chain several tasks together in a single environment.
Its agents can be used in particular for:
- reviewing large numbers of documents;
- analysing complex matters;
- collaborating across teams;
- managing multi-step processes.
Legora is aimed above all at large organisations that want to automate a significant part of their workflows.
Silex: an assistant designed for Swiss law
Silex is a legal assistant built for professionals working in Swiss law.
It is designed to help search for sources, analyse a question and prepare legal documents, while leaving final validation to the professional.
According to Silex, the platform draws on more than 800,000 regularly updated Swiss legal sources, including laws, ordinances and court decisions.
The main features are presented on the product page.
Two different approaches
Legora puts the emphasis primarily on automating end-to-end processes.
Silex focuses more on legal research, analysis and drafting in Swiss law.
In practice:
- Legora suits organisations that want to automate complex workflows;
- Silex suits professionals who want a sourced legal analysis in Swiss law.
Where do the answers come from?
A legal AI must allow the professional to check the sources used.
Legora offers research adapted to different jurisdictions, with international coverage. For a question of Swiss law, it is therefore important to check which sources are used.
Silex works from its corpus of Swiss law and accompanies its answers with references that the legal professional can consult.
This traceability makes it possible to check that a cited law, decision or rule actually matches the question under consideration.
Working with the firm’s documents
Both tools can make use of a firm’s internal documents.
With Silo, Silex can analyse contracts, case files, notes or internal precedents and relate them to the applicable Swiss law.
In particular, this feature can be used to:
- summarise a case file;
- find information across several documents;
- analyse a contract;
- link the facts of the case to the relevant legal rules.
To better understand how it differs from a general-purpose tool, see our comparison ChatGPT or Silex.
Legora can also work with the firm’s precedent libraries and document management systems.
Security and data hosting
Confidentiality is essential for firms bound by professional secrecy.
Legora states that it complies with security standards such as SOC 2 Type II and ISO 27001, as well as the GDPR. According to the provider, client data is not used to train or improve the models.
The hosting location depends on the region specified in the contract.
Silex, for its part, states that it hosts data in Switzerland with Infomaniak and does not use client files to train its models.
Details are available on the security page and in our article AI and data protection.
Integration with the firm’s tools
Legora offers several tools to centralise legal work, including Word and Outlook integrations, a mobile app and a client collaboration portal.
Silex instead aims to integrate with the tools professionals already use.
The integration of Silex into WinLex and SkyLex, for example, makes it possible to run a search without leaving the practice management software.
The partnership with MCR Solutions also aims to integrate legal research into existing workflows.

In short
Legora and Silex meet two different needs.
Legora is mainly intended for large organisations that want to automate complex, collaborative legal processes.
Silex focuses on research and analysis in Swiss law, with verifiable sources and data hosting in Switzerland.
The choice therefore depends above all on your need for automation, your confidentiality requirements and the importance of Swiss legal sources in your work.
