This article explains how to verify an answer, and where the limits are. ### Can I rely on a Silex answer as it is? Not without verification. Silex is a decision-support tool. Source verification and final legal responsibility remain with the professional using it. Silex is designed so that this verification takes seconds rather than minutes: every statement carries a numbered source bubble with the source type, an excerpt and a direct link to the original text. ### What is a hallucination, and can it happen in Silex? A hallucination is a statement produced by an AI that looks plausible and well-formed but is not supported by a real source — an invented reference number, a ruling attributed to the wrong court, or a fact that does not appear in the document you uploaded. Silex reduces this risk substantially by grounding answers in an indexed database of Swiss legal sources and by exposing the source behind each statement. It does not eliminate it. Like every AI-assisted tool, Silex can occasionally produce an inaccurate statement, which is why the source bubbles exist. ### In which situations should I be most attentive? - Precise reference numbers — circular numbers, ruling references, article numbers. Open the bubble and confirm the reference exists as cited. - Case law cited across legal domains — a civil ruling invoked in an administrative question, for example. Check that the cited decision genuinely concerns your domain. - Analysis of documents you uploaded — verify that quoted passages actually appear in your document, and note that a submitted file may contain a party's arguments rather than established facts; Silex may reproduce them as if they were settled. - Very recent case law — the database is updated weekly, so a ruling published in the last few days may not yet be indexed. - Anything based on web sources — these do not come from the Silex database and warrant enhanced verification. ### How do I verify an answer in practice? Click the numbered bubble next to a statement. It shows the source type (federal law, cantonal law, case law, web), an excerpt of the passage the statement relies on, and an "Access the source" link that opens the original text — for example on fedlex.admin.ch for a statutory article. Concentrate your checks on the statements that carry your conclusion. ### An answer is wrong or a reference does not exist. What should I do? Use the feedback button below the answer to flag it. This is the fastest route for the team to identify and correct a pattern. For anything blocking, write to support@silex.legal with the question you asked and the problematic statement. ### Does Silex learn from my corrections? Not automatically, and not from your data. Silex does not train its AI models on user conversations. Feedback you send is reviewed by the team and used to improve the product, but your conversations are never used as training material. ### Why did I get a different answer to the same question? AI-generated answers are not deterministic: the same question can produce a differently worded answer. The underlying sources should be consistent. If two answers contradict each other on substance, open the source bubbles on both and let the original text settle it — then flag it through the feedback button.  - [General](https://help.silex.legal/en/knowledge-base/general?hsLang=en#main-content) - [Silo Functionnality](https://help.silex.legal/en/knowledge-base/general?hsLang=en#silo-functionnality) - [Translator Agent](https://help.silex.legal/en/knowledge-base/general?hsLang=en#translator-agent) - [Anonymizer Agent](https://help.silex.legal/en/knowledge-base/general?hsLang=en#anonymizer-agent) - [Document Comparison Agent](https://help.silex.legal/en/knowledge-base/general?hsLang=en#document-comparison-agent) - [Meeting Minutes Agent](https://help.silex.legal/en/knowledge-base/general?hsLang=en#meeting-minutes-agent) - [Silex Chat](https://help.silex.legal/en/knowledge-base/general?hsLang=en#silex-chat) - [Account, Organisation & Billing](https://help.silex.legal/en/knowledge-base/general?hsLang=en#account-organisation-billing) - [Getting started](https://help.silex.legal/en/knowledge-base/getting-started?hsLang=en#main-content) - [Silo Functionnality](https://help.silex.legal/en/knowledge-base/getting-started?hsLang=en#silo-functionnality) - [Translator Agent](https://help.silex.legal/en/knowledge-base/getting-started?hsLang=en#translator-agent) - [Anonymizer Agent](https://help.silex.legal/en/knowledge-base/getting-started?hsLang=en#anonymizer-agent) - [Document Comparison Agent](https://help.silex.legal/en/knowledge-base/getting-started?hsLang=en#document-comparison-agent) - [Meeting Minutes Agent](https://help.silex.legal/en/knowledge-base/getting-started?hsLang=en#meeting-minutes-agent) - [Silex Chat](https://help.silex.legal/en/knowledge-base/getting-started?hsLang=en#silex-chat) - [Account, Organisation & Billing](https://help.silex.legal/en/knowledge-base/getting-started?hsLang=en#account-organisation-billing) - [Integrations](https://help.silex.legal/en/knowledge-base/integrations?hsLang=en#main-content) - [Silo Functionnality](https://help.silex.legal/en/knowledge-base/integrations?hsLang=en#silo-functionnality) - [Silex Chat](https://help.silex.legal/en/knowledge-base/integrations?hsLang=en#silex-chat) - [Plans & Billing](https://help.silex.legal/en/knowledge-base/plans-billing?hsLang=en#main-content) - [Translator Agent](https://help.silex.legal/en/knowledge-base/plans-billing?hsLang=en#translator-agent) - [Anonymizer Agent](https://help.silex.legal/en/knowledge-base/plans-billing?hsLang=en#anonymizer-agent) - [Document Comparison Agent](https://help.silex.legal/en/knowledge-base/plans-billing?hsLang=en#document-comparison-agent) - [Meeting Minutes Agent](https://help.silex.legal/en/knowledge-base/plans-billing?hsLang=en#meeting-minutes-agent) - [Silex Chat](https://help.silex.legal/en/knowledge-base/plans-billing?hsLang=en#silex-chat) - [Account, Organisation & Billing](https://help.silex.legal/en/knowledge-base/plans-billing?hsLang=en#account-organisation-billing) - [Security & privacy](https://help.silex.legal/en/knowledge-base/security-privacy?hsLang=en#main-content) - [Silo Functionnality](https://help.silex.legal/en/knowledge-base/security-privacy?hsLang=en#silo-functionnality) - [Translator Agent](https://help.silex.legal/en/knowledge-base/security-privacy?hsLang=en#translator-agent) - [Document Comparison Agent](https://help.silex.legal/en/knowledge-base/security-privacy?hsLang=en#document-comparison-agent) - [Meeting Minutes Agent](https://help.silex.legal/en/knowledge-base/security-privacy?hsLang=en#meeting-minutes-agent) - [Silex Chat](https://help.silex.legal/en/knowledge-base/security-privacy?hsLang=en#silex-chat) - [Account, Organisation & Billing](https://help.silex.legal/en/knowledge-base/security-privacy?hsLang=en#account-organisation-billing) - [Troubleshooting](https://help.silex.legal/en/knowledge-base/troubleshooting?hsLang=en#main-content) - [Silo Functionnality](https://help.silex.legal/en/knowledge-base/troubleshooting?hsLang=en#silo-functionnality) - [Translator Agent](https://help.silex.legal/en/knowledge-base/troubleshooting?hsLang=en#translator-agent) - [Anonymizer Agent](https://help.silex.legal/en/knowledge-base/troubleshooting?hsLang=en#anonymizer-agent) - [Document Comparison Agent](https://help.silex.legal/en/knowledge-base/troubleshooting?hsLang=en#document-comparison-agent) - [Meeting Minutes Agent](https://help.silex.legal/en/knowledge-base/troubleshooting?hsLang=en#meeting-minutes-agent) - [Silex Chat](https://help.silex.legal/en/knowledge-base/troubleshooting?hsLang=en#silex-chat) - [Account, Organisation & Billing](https://help.silex.legal/en/knowledge-base/troubleshooting?hsLang=en#account-organisation-billing) [![logo-KB](https://help.silex.legal/hubfs/logo-KB.svg "logo-KB")](https://help.silex.legal/en/knowledge-base?hsLang=en)  support@silex.legal Copyright © 2026, Silex - Ex Nunc Intelligence SA
