Question 1

Does LEXchat replace the legal review?

Accepted Answer

No. LEXchat researches, structures, asks and suggests; it does not judge or decide. Conflict check, mandate acceptance, release of the pseudonymised version and the assessment of the first analysis are deliberate legal acts by a lawyer — logged with person and time. The BGFA lawyers' monopoly remains untouched. You save the structuring groundwork, not the responsibility.

Question 2

Where are my dossiers held?

Accepted Answer

In Switzerland: application, database and sign-in run at Infomaniak in Geneva, backups at Exoscale — deliberately a second, independent Swiss provider. They are encrypted before they leave our servers; the private key is held on no server. Only the public statutory and case-law corpus, which contains no dossier data, is located in Germany.

Question 3

Which data leaves Switzerland?

Accepted Answer

Before the mandate is accepted, no analysis model runs on the case. Afterwards only the placeholder version you released leaves the Swiss platform: it goes to the search in the legal corpus in Germany and — depending on the configuration of your access — to a language model in Switzerland or in EU data centres. The mapping table stays in Switzerland. What we do not claim: end-to-end encryption in the analysis path, or “no data ever leaves Switzerland”.

Question 4

Which model providers are used?

Accepted Answer

Infomaniak in Geneva for pseudonymisation, preparation of the facts, pre-selection of sources and the search — and, in the configuration with Switzerland as processing region, for the first analysis itself. Alongside that, Anthropic for the first analysis and OpenAI for preparing the query, both optionally via Amazon Bedrock in EU data centres. Which provider processes in which country on which basis is stated per provider in Annex B of the data processing agreement and in sec. 6 of the privacy policy.

Question 5

Is my data used for training?

Accepted Answer

No. We deploy every provider only in a contractual configuration that excludes the use of customer content for training or improving general models, and document that before productive use. Individual providers reserve a time-limited retention for abuse detection, regularly up to 30 days. LEXchat itself does not train models on client data either.

Question 6

What does pseudonymisation mean in practice?

Accepted Answer

Names, addresses, AHV numbers and other direct identifiers are recognised on a model computed in Switzerland and replaced with placeholders — red turns blue. You check the cleaned version in the interface and release it; only this version goes into search and analysis. The mapping table stays on the Swiss platform; the finished analysis shows the real names again. Legally the version is pseudonymised, not anonymised: it remains personal data, and it does not replace your review under the GTC.

Question 7

Can I process sensitive personal data?

Accepted Answer

Client data regularly contains it; the platform is designed for that. You remain the controller, LEXchat acts as processor on the basis of the data processing agreement with professional-secrecy clauses. Operations subject to logging under Art. 4 of the Swiss Data Protection Ordinance are retained for at least twelve months, separately from the productive system. What you enter is your decision — no real client data in test and evaluation environments.

Question 8

How current is the legal corpus, and which sources does it contain?

Accepted Answer

Federal law from Fedlex, the cantonal enactments we have captured, and decisions of the Federal Supreme Court and cantonal courts via entscheidsuche.ch. The corpus is updated regularly; the service shows the date of the last update. We do not guarantee that every newly published change is included on the day of your query. Cantonal coverage is not equally deep in every canton — ask us about yours and we will tell you the measured state.

Question 9

How does LEXchat deal with hallucinations?

Accepted Answer

With source binding, not with promises. The model answers on the basis of the references the corpus search returns; every norm and decision cited is linked and verifiable in two clicks. That reduces the risk, it does not remove it: citation stance, deadlines and the assignment of considerations remain error-prone. Treat a statement without a reference as an unsupported claim — the AI disclosure names the typical error classes openly.

Question 10

Are the cited decisions directly verifiable?

Accepted Answer

Yes. Every decision is linked to its source (Federal Supreme Court, entscheidsuche.ch), every norm to the official version on Fedlex; a decision's facts and headnote can be expanded in the dossier without leaving the platform. Whether a decision cites a norm in support or to distinguish it is for you to check — that is exactly what the reference is for.

Question 11

Which documents can I upload?

Accepted Answer

In Kanzlei.Pro the client uploads contracts, letters and photos during intake — common file types, up to 20 MB per file, with a preview before sending — and submits more later through the client portal; the documents sit in the dossier. Today the first analysis works from the facts, not from the wording of the documents, and scans or phone photos are not yet read by OCR. Both belong in the pilot agreement, not in a promise.

Question 12

What happens to my data if I cancel?

Accepted Answer

Both lines can be cancelled monthly to the end of the billing period. Then 30 days of read-and-export mode: facts, analyses with source references and dossier metadata as JSON. After that we delete customer content from the productive system within a further 30 days; backups expire with their retention periods — daily backups after 35 days, monthly snapshots after at most twelve months — and are not restored.

Question 13

Is there a data processing agreement?

Accepted Answer

Yes, for every firm from the first access — Annex 1 to the GTC, with professional-secrecy clauses, instruction binding, audit right, technical and organisational measures and the list of sub-processors. It is presented in the portal before acceptance, delivered in text form and signed separately on request; it is not published publicly.

Question 14

Which areas of law is the system suited for?

Accepted Answer

Employment law today; that is also where the public example first analysis sits. Further areas follow once their coverage has been measured — we name an area only when we can substantiate it. LEXchat does not cover foreign law. Bring your own case without real names: three analyses before you decide are free of charge.

Question 15

Where are the limits of the first analysis?

Accepted Answer

It is groundwork, not a legal product: no case-by-case assessment, no procedural strategy, no deadline calculation, no foreign law. A date, a contract clause, a residence abroad can overturn the result, and the AI can overlook or misweight such details. What it delivers: structure, references, open questions — so that your review starts where it belongs.

Question 16

What does onboarding look like?

Accepted Answer

You request access here on lexchat.ch — product choice, firm name, address and, for Kanzlei.Pro, the firm's domain; two minutes. We review the request and activate your firm personally, no self-service. Kanzlei.Recherche: at your first login you accept the contract documents and are productive within 15 minutes. Kanzlei.Pro: add your logo and colours, your firm's imprint and privacy policy, and a CNAME record lexchat.your-firm.ch set by your IT — with those in place you set up the intake in the console yourself. On request we give you and your team a personal introduction.

Question 17

There are several of us at the firm — how do we use LEXchat?

Accepted Answer

Each person gets their own seat — access is personal, as professional secrecy and traceability require. In Kanzlei.Pro the mandate belongs to the firm, not to an account: roles, deputising and membership in more than one firm are provided for, and the log records who saw, changed or released what and when. Research is fully included; no separate research seat is needed. Anyone who only wants the legal question answered at their own desk takes Kanzlei.Recherche — one seat per person.

Question 18

What does “unlimited under fair use” mean?

Accepted Answer

There is no quota and no per-analysis price. The guide value is 40 analyses per seat and month — deliberately more than normal operation needs. Only the analysis itself counts: follow-up questions and chat cost nothing extra. The guide value is not a cap: anyone regularly above it gets a call from us and a suitable offer — not an invoice. Details, including the optional Boost-Credits, are in the services and price overview.
