Gemini Enterprise and Silex are two artificial intelligence solutions that can support legal professionals in their research, analysis and the drafting of documents. They nevertheless meet different needs, in particular as regards legal specialisation, data management and integration with professional tools.
In this article, Gemini Enterprise designates Google’s professional offering, which can in particular be integrated with Google Workspace and include the Gemini for Legal module. It is not the Gemini application intended for the general public.
Gemini Enterprise is aimed mainly at companies and organisations that wish to integrate artificial intelligence into their working tools. Its legal module in particular makes it possible to use internal documents, carry out analyses and access certain legal resources thanks to connectors.
For its part, Silex is a Swiss artificial intelligence designed specifically for the research and analysis of federal and cantonal law. The platform relies on verifiable legal sources and favours hosting of data in Switzerland.
To compare these two approaches, several criteria must be examined: coverage of Swiss legal sources, document-analysis features, confidentiality of information, the place where data is processed and the possibilities of integration with the software used in law firms.
Gemini Enterprise: an enterprise artificial intelligence with legal features
Gemini is the artificial intelligence assistant developed by Google. In a professional environment, it can be integrated into Google Workspace applications, Google Cloud services and various tools used daily by companies.
Its aim is to make many tasks easier, such as searching for information, drafting documents, analysing data and automating certain work processes.
In 2026, Google announced Gemini for Legal, a legal module offered in preview within Gemini Enterprise.
This module is not a standalone application. It complements the Gemini Enterprise environment by offering agents and connectors adapted to the needs of legal departments and law firms.
According to Google, Gemini for Legal can in particular help professionals to:
- Analyse and review contracts: examine clauses, identify certain important points and propose amendments.
- Carry out regulatory monitoring: follow legislative and regulatory developments relevant to an organisation.
- Create internal guides: build procedures and reference materials, also called playbooks, to harmonise the handling of certain legal tasks.
- Prepare responses to data-access requests: make it easier to collect and organise the information needed.
- Connect different platforms: use resources from Microsoft 365, iManage, NetDocuments or certain legal databases.
The first users presented by Google include in particular large international law firms.
This approach is aimed mainly at organisations that wish to have an artificial intelligence environment common to several functions, with centralised management of access, data and security settings.
Silex: an artificial intelligence specialised in Swiss law
Silex is a Swiss legal assistant developed for professionals who work mainly with federal law and cantonal legislation.
Unlike a general-purpose artificial intelligence solution, Silex concentrates on the needs linked to legal research, the analysis of court decisions and the use of the documents used in files.
The platform in particular helps lawyers find statutory provisions, identify relevant sources, structure an analysis and prepare draft documents.
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 can be consulted, enabling professionals to find the texts on which the analysis rests.
The aim is to make access to legal information easier while retaining the possibility of checking the original sources.
As with any legal artificial intelligence solution, the user 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: what differences are there between Gemini Enterprise and Silex?
The reliability of sources is one of the most important criteria when a legal professional uses an assistant based on artificial intelligence.
A platform can produce a clear, convincing and correctly drafted answer without the legal references mentioned necessarily being accurate, up to date or applicable to the file concerned.
It is essential to be able to find and check the texts on which an analysis rests.
Gemini Enterprise: research based on documents and connected databases
According to Google, Gemini for Legal can rely on an organisation’s internal documents as well as on certain legal databases to which it has authorised access.
Thanks to connectors, the platform can use information from various document systems and use it to produce answers accompanied by references.
Google also states that these connectors take account of the permissions already defined in the systems concerned. The aim is to let users access only the information for which they have the necessary rights.
The quality and extent of legal research nevertheless depend on the connected resources, the licences available and the configuration chosen by the organisation.
Silex: a corpus devoted to Swiss law
Silex takes a different approach by relying directly on a documentary corpus devoted to the Swiss legal system.
According to the publisher, the platform makes it possible to search Swiss legislation and case law, then to consult the references used in the answers.
This specialisation aims to make the work of professionals easier when they regularly have to analyse questions falling under federal or cantonal law.
Which approach should be favoured for legal research?
The main difference lies in the starting point of each solution.
Gemini Enterprise belongs to a broader enterprise environment. Its legal capabilities rest in particular on the tools, documents and databases to which the organisation has access.
Silex is designed around research in Swiss law, with a national legal corpus and references intended to be checked by the professional.
In both cases, a citation is not enough to guarantee the reliability of an answer. The lawyer must consult the original source, check the date of the text, the court concerned and the relevance of the rule for the file being handled.
To go further into this method, see our article on legal analysis assisted by artificial intelligence.
The particularities of Swiss law: an essential element
The Swiss legal system has several particularities that professionals must take into account when they use an artificial intelligence tool.
It rests in particular on the relationship between federal law and the various cantonal legislations. Added to this are the case law of the Federal Supreme Court, the decisions of cantonal courts and the use of several languages in legal practice.
The same question may thus require consulting texts in French, German or Italian, while taking account of the rules applicable in a particular canton.
This complexity requires particular care when a legal assistant has been developed for an international market.
Gemini Enterprise may in particular be of interest to organisations that handle international contracts, carry out regulatory monitoring in several countries or work on files involving different legal systems.
For a question falling specifically under Swiss law, it is nevertheless advisable to check that the sources used correspond to the applicable legislation and that the answer does not mix rules from different countries.
Silex was designed to address the particularities of the Swiss legal system, in particular the coexistence of federal and cantonal rules.
Gemini Enterprise remains, for its part, an enterprise artificial intelligence platform, whose legal features depend in particular on the modules and connectors made available.
For a practice that is essentially Swiss, the actual coverage of national sources must therefore be a central criterion in the choice of solution.
Document analysis and management of legal files
Gemini Enterprise and Silex can both contribute to the analysis of internal documents. Their operation and their integration into work processes are nevertheless different.
Gemini Enterprise: using the organisation’s documents
Gemini Enterprise is mainly designed to operate in the IT environment already used by a company.
Depending on the applications and connectors activated, the assistant can use information from Google Drive, Gmail, Microsoft 365 or various document-management platforms.
It can also take part in certain processes linked to document search and e-discovery, that is the search for and analysis of electronic documents in a legal context.
According to Google, access to data takes account of the permissions assigned to each user. The assistant should not make it possible to consult documents to which the person does not already have authorised access.
This approach may be of interest to organisations that have a large volume of documents spread across several applications and wish to make them easier to use.
Silex: analysing legal documents with Silo
Silex offers a feature called Silo, intended for the analysis of the internal documents of law firms and organisations.
It in particular makes it possible to examine contracts, notes, files and precedents, then to relate their content to the relevant Swiss legal sources.
This approach aims to associate the information present in the firm’s documents with the results of legal research.
Silex also provides several specialised agents to make certain everyday tasks easier:
- Anonymisation: mask the names of the parties and sensitive data in the documents by redaction.
- Legal translation: translate texts into French, German, Italian and English.
- Document comparison: identify the changes made between two versions of the same file.
- Creation of minutes: turn an audio recording into a structured report.
These features can in particular be useful when a file must be sent, a document must be anonymised, a contract requires a version comparison or a meeting must be recorded in minutes.
Two approaches adapted to different environments
Gemini Enterprise favours the use of the information available in the organisation’s IT ecosystem, with search, drafting and summary functions integrated into various applications.
Silex offers an approach more centred on legal work, by associating document analysis with Swiss law sources and specialised features.
Gemini can also make it possible to transcribe, summarise or draft content depending on the Google applications used. These possibilities do not, however, necessarily correspond to the same uses as an assistant designed to link the documents in a file to Swiss legal research.
Whatever solution is used, generated, translated or amended documents must be checked before any professional use.
Data hosting, confidentiality and professional secrecy
Data protection is a major issue for law firms, notaries’ offices and other professionals who handle confidential information.
When a file contains personal data or information covered by professional secrecy, it is essential to know the conditions under which these elements are stored, processed and possibly transmitted to external providers.
The place of hosting is, however, only one of the criteria to be examined. Account must also be taken of the location of query processing, the security measures and the processors involved in the operation of the platform.
Gemini Enterprise: security and data-residency options
According to Google, client data, the instructions sent to the models and the answers generated in Gemini Enterprise are not used to train the foundation models.
The professional offerings also provide various security and governance mechanisms, in particular:
- encryption of information, with options for client-managed keys;
- network-segmentation mechanisms;
- access controls and user management;
- data-residency options depending on the offering and the configuration chosen.
These features allow companies to adapt certain security settings to their organisational and regulatory needs.
The location of data nevertheless requires particular attention for organisations established in Switzerland.
According to the public documentation mentioned in this comparison, Gemini Enterprise’s data-residency options concern in particular the United States, the European Union and certain other countries expressly provided for.
Switzerland does not appear there as a dedicated residency region. Moreover, an option of processing in the European Union does not mean that the data is processed in Switzerland.
Before transmitting confidential documents, it is essential to check the guarantees applicable to the edition subscribed, the region actually configured and any processors involved.
Silex: hosting of data in Switzerland
Silex states that it hosts its users’ data in Switzerland, with Infomaniak.
According to the publisher, the information 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 Swiss infrastructure for the processing of their legal documents.
It is nevertheless advisable to check the applicable contractual conditions, the security measures and the arrangements for access to confidential information.
Which points should be checked before choosing?
For a Swiss law firm, it is advisable to examine not only the place where data is stored, but also the place where queries are actually processed.
It is also necessary to check access permissions, any international transfers, technical processors and the contractual provisions relating to confidentiality.
The guarantees announced by Silex are presented on its page dedicated to security. You can also see our article on artificial intelligence and data protection.
Integration with the software used in law firms
A legal assistant’s ability to work with the software already used is another important criterion.
Good integration in particular makes it possible to simplify certain tasks and to limit changes of application during everyday work.
Gemini Enterprise: integration with the Google ecosystem and enterprise tools
Gemini Enterprise integrates mainly with Google Workspace applications and Google Cloud services.
Thanks to its connectors, the platform can also be associated with various professional tools, in particular Microsoft 365, iManage and NetDocuments, as well as certain legal databases.
This approach may interest large organisations that use several document systems and wish to centralise certain artificial intelligence features.
It also makes it possible to place legal uses of AI within a broader IT strategy, common to different departments of the company.
Silex: integration with Swiss practice software
Silex favours integrations with the practice-management tools already used by legal professionals in Switzerland.
The integration of Silex into WinLex and SkyLex in particular makes it possible to launch legal research directly from these programs, without having to leave the file-management environment.
The partnership between Silex and MCR Solutions pursues a similar approach, by seeking to integrate legal research assisted by artificial intelligence into 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 depends in part on your IT environment. Organisations that mainly use Google services may be interested in Gemini Enterprise, whereas professionals equipped with certain Swiss practice-management programs may examine the possibilities offered by Silex.
Gemini Enterprise and Silex pricing: how to compare them?
Gemini Enterprise and Silex adopt different pricing models, which makes a direct comparison of prices relatively complex.
Gemini Enterprise pricing
Google offers several editions of Gemini Enterprise, generally billed per user and expressed in United States dollars.
The amount depends in particular on the edition chosen, the number of users, the features included and any data-residency options.
The Gemini for Legal module complements the Gemini Enterprise environment. Access to it and its commercial terms may depend on the configuration and the services chosen by the organisation.
For large deployments, pricing terms are often the subject of a tailored offer.
It is thus necessary to request an adapted proposal in order to assess the overall cost of the solution, including additional modules and any integration costs.
Silex pricing
Silex presents several monthly plans in Swiss francs, adapted to independent professionals and to 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 the various subscriptions are detailed on Silex’s pricing and solutions pages.
Which solution represents the better investment?
Price must not be the only comparison criterion.
Gemini Enterprise can form part of an artificial intelligence project at company scale, with uses that go well beyond the legal field.
Silex offers a solution specifically intended for Swiss legal work, with subscriptions whose amounts are published in Swiss francs.
To assess the actual cost, it is advisable to take account of the number of users, the features actually required, integration costs and the organisation’s own security requirements.
The pricing information presented here must be confirmed with the providers before any subscription.
