Frequently Asked Questions

Our servers and AI models are hosted exclusively in Europe on infrastructures that respect ISO 27001 certification, ensuring your data remains under the protection of European laws. Unlike American AIs, nothing transits through third-party servers outside our jurisdiction.

Absolutely not. This is the fundamental difference of LetzAgents. Your instance is private and isolated ("siloed"). Your data is only used to answer your questions and is never used to train the global model or shared with other companies.

Yes. By keeping total control over where your data is stored and processed, LetzAgents allows you to deploy a generative AI while remaining perfectly compliant with the strict requirements of the GDPR.

ChatGPT is a "public" and generalist AI: your conversations can be used to train it and your data can leave Europe, posing a data leak risk and GDPR compliance risk. Even more so if it's confidential data. LetzAgents is a private and sovereign AI, connected to your internal knowledge base, secure and audited.

Our solution can ingest and analyze most standard business formats: PDF files, Word documents, Excel files, web pages, audio files and internal databases. You choose exactly what the AI has access to.

We use a technology called RAG (Retrieval-Augmented Generation). Concretely, the AI only responds based on your source documents and can cite its sources (e.g.: "Information found on page 12 of the HR PDF"). This drastically reduces the risk of error compared to a classic AI.

No. Our solution is designed to be deployed quickly without disrupting your current infrastructure. We take care of the configuration, ingesting your documents and training your teams so you can focus on the essentials: running your business.

Initial deployment typically takes 1 to 2 weeks, including infrastructure setup, document ingestion and team training.

Our solution supports PDF, Word, Excel, PowerPoint, web pages, text and audio files. We can also connect to your existing databases.

Thanks to RAG (Retrieval-Augmented Generation) technology, the AI is based solely on your source documents and cites its references. This drastically reduces the risk of error compared to generalist AIs.

Yes, you have full control over access. You can define roles, restrict certain documents to certain user groups and audit all queries.

We offer monthly packages tailored to your organization's size and usage volume. Contact us for a personalized quote.

Integration is quick: copy-paste a simple JavaScript snippet on your site. Full deployment, including customization and training the assistant on your content, typically takes 1 to 2 weeks.

Yes, our assistant is multilingual and can communicate in French, English, German and Luxembourgish. It automatically detects the visitor's language.

The assistant is configured to recognize its limits. It can either suggest alternative responses or transfer the conversation to a team member with the full discussion context.

Absolutely. You can customize colors, logo, welcome messages and widget style to perfectly match your brand identity.

Yes, all data is hosted in Europe on ISO 27001 certified and GDPR compliant servers. No data is used to train third-party models.

The agent speaks French, English, German and Luxembourgish. It automatically detects the caller's language and adapts.

We configure a dedicated phone number or redirect your existing calls to the agent. Integration with your tools (calendar, CRM) is done via API.

Yes, all conversations are recorded and transcribed. They are securely stored on European servers compliant with GDPR.

Our agents can automate a wide range of repetitive tasks: data entry and updates, document processing (invoices, contracts, mail), software synchronization, client follow-ups, report generation, onboarding and much more. Any process involving defined business rules can be automated.

Our agents connect via secure APIs to major market software: CRM (Salesforce, HubSpot, Dynamics), ERP (SAP, Odoo), accounting (Sage, Bob50), email (Outlook, Gmail) and many others. Integration is configured by our team with no impact on your infrastructure.

No. Our agents are configured through an intuitive interface, without any code. Our team supports you during the initial setup and trains you for autonomous agent management. You can modify rules and workflows yourself.

All data is encrypted (AES-256) at rest and in transit. Our servers are hosted exclusively in Europe (Germany), ISO 27001 certified. Your data is never used to train models. A complete audit trail traces every action of every agent.

We offer monthly packages tailored to the number of deployed agents and the volume of tasks processed. Each package includes integration, maintenance and support. Contact us for a personalized quote adapted to your needs.

ChatGPT is a public AI whose servers are in the United States and which can use your conversations to improve itself. A private AI is hosted in Europe, on infrastructure dedicated to your company. Your data never leaves your environment and is never used to train other models.

Company size isn't the main criterion. If you handle customer data, contracts, financial information or any confidential data, a private AI protects you from leak risks and GDPR fines that can reach 20 million euros or 4% of global turnover.

Initial deployment typically takes 1 to 2 weeks, including infrastructure configuration, document ingestion and team training. You can start using the AI from the first week.

Yes, and even more so for your specific use cases. We use cutting-edge open source models (Mistral, Qwen) optimized on dedicated GPUs. Additionally, since the AI is trained on your documents, it gives more precise and contextualized answers than ChatGPT for your domain.

You remain the owner of all your data. Upon termination, we provide you with a complete export of your knowledge base and permanently delete all your data from our servers, in accordance with GDPR.

Yes, we offer a complete and documented REST API that allows you to integrate AI into your existing workflows: CRM, ERP, ticketing tools, databases, etc. We can also develop connectors specific to your needs.

No, and that's not its role. AI is an assistant that accelerates information research, document analysis and file preparation. Professional judgment and validation remain the responsibility of the accountant or auditor. AI saves time on low-value tasks to free up time for advisory.

By architecture: your instance is isolated and hosted in Europe on ISO 27001 certified servers. No data passes through third-party servers. No shared model has access to your documents. The entire processing chain remains under European jurisdiction.

Yes. In addition to its general knowledge, the AI relies on your own technical documents to respond with your firm's vocabulary and precision. The more you enrich the document base with your circulars and internal notes, the more relevant and specific the answers become.

Initial deployment takes a few days. Document base ingestion depends on volume, but first results are visible within a week. The phone agent and web chatbot can be operational in parallel.

LetzAgents offers plans adapted to all firm sizes. The cost is a company flat rate, not a per-user price - making it particularly advantageous for firms where several employees use AI.

No, and that's not its role. AI is an assistant that accelerates information research, administrative management and patient reception. Diagnosis and medical decisions remain the exclusive responsibility of the doctor.

By architecture: your instance is isolated and hosted in Europe on ISO 27001 certified servers. No data passes through third-party servers. No shared model has access to your patients' information.

No. The chatbot is limited to practical and general information: hours, pre-exam preparation, documents to bring, appointment booking. It never provides personalized medical advice.

Initial deployment takes a few days. Protocol and FAQ ingestion depends on volume, but first results are visible within a week.

LetzAgents offers plans adapted to all practice sizes. The cost is a company flat rate, not a per-user price.

No, and that's not its role. AI qualifies prospects, answers common questions and accelerates administrative tasks. Viewings, negotiations, personalized advice and the human relationship remain the core of the real estate profession.

Yes, if your property database is integrated into LetzAgents. The chatbot can suggest properties matching the prospect's criteria, provide key features and offer to schedule a viewing.

LetzAgents is natively multilingual (French, English, German, Luxembourgish). The chatbot and phone agent detect the prospect's language and respond in the same language.

Initial deployment takes a few days. Ingesting your property portfolio and documentation is fast. The web chatbot and phone agent can be operational within a week.

LetzAgents offers plans adapted to all agency sizes. The cost is a company flat rate, not a per-user price.

No. AI is an assistant that accelerates research, analysis and drafting. Legal reasoning, strategic advice, advocacy and deed authentication remain human prerogatives. AI saves time on low-value tasks to let professionals focus on counsel and strategy.

AI use is not prohibited per se, but it must respect professional secrecy and ethical obligations. That's precisely the advantage of a private and sovereign AI: it allows AI use in a compliant framework. We recommend consulting your Bar President for specific ethical questions.

Traditional legal databases offer access to texts and case law via keyword search engines. LetzAgents goes further: the AI understands your questions in natural language, simultaneously searches public sources AND your internal documentation, and provides synthetic answers with source citations.

Through technical architecture: isolated instance hosted in Europe on ISO 27001 certified servers, no data transfer to third parties, no use for model training, complete access traceability.

Initial deployment takes a few days. Document base ingestion depends on volume, but first results are visible within a week.

LetzAgents offers plans adapted to all structure sizes. The cost is a flat rate, not per user - making it advantageous for firms with multiple staff members. Check our pricing for your situation.

No. AI is an assistant that frees up time on repetitive tasks (answering the same questions, creating first drafts, searching documentation). The trainer remains essential for teaching, individual support, group facilitation and qualitative assessment. AI lets them focus on what they do best.

Yes. LetzAgents relies solely on the documents you provide: course materials, programs, technical sheets, internal FAQs. The AI only answers based on your content, with source citations. If a question goes beyond the documentation scope, the AI clearly indicates this and directs to a human trainer.

LetzAgents natively handles French, German, English and Luxembourgish. The AI detects the learner's or prospect's language and responds in the same language, even if source documents are in another language.

Yes. LetzAgents is hosted in Europe on ISO 27001 certified servers, with an isolated instance. For organizations under public oversight or funded by public funds, the solution meets sovereignty and GDPR compliance requirements.

Initial deployment takes a few days. Ingestion of your course materials depends on volume, but first results are visible within a week. Most organizations start with a web chatbot and internal assistant, then add the phone agent later.

LetzAgents offers plans adapted to all structure sizes. The cost is a flat rate, not per learner or per trainer, making it advantageous for organizations with many users. Check our pricing for your situation.

LetzAgents is hosted in Europe on ISO 27001 certified servers, with an isolated and dedicated instance. No data passes through non-European servers. We can provide the technical documentation needed for validation by your CISO or oversight authority.

Yes. LetzAgents can connect to your existing tools via APIs. Integration depends on your technical environment and is analyzed during the scoping phase.

LetzAgents only reflects the information you provide it. The knowledge base is entirely under your control: you decide which documents go in, which agents access them, and which responses are validated. The AI takes no position - it returns information from your documents with source citations.

Yes. The solution is modular: you activate the agents you need (chatbot, phone, internal assistant). A 30-person structure can start with a web chatbot and internal assistant. The package doesn't depend on the number of users.

Deployment depends on your environment's complexity. For a standard case (chatbot + internal assistant), expect a few weeks including scoping, document ingestion and testing.

LetzAgents offers adapted plans: an SME offer for modest-sized structures and an Enterprise offer for larger organizations, both including sovereign hosting and support. Contact us for a proposal adapted to your situation.

The AI helps compare products and identify relevant options, but the final recommendation remains the broker's responsibility. The duty of advice is a professional obligation that cannot be delegated to a tool, however intelligent. The AI accelerates analysis, the broker makes the decision.

Health data benefits from enhanced protection under the GDPR (Article 9). LetzAgents' European hosting, instance isolation and absence of transfers to third parties ensure compliant processing. No health data passes through shared models.

The chatbot can qualify the prospect's need and collect the information needed to prepare a quote. Generating the quote itself depends on integration with your pricing tools. In all cases, the chatbot speeds up the qualification process and allows the broker to prepare a quote faster.

LetzAgents is designed to help brokers meet their regulatory obligations, not circumvent them. European hosting, exchange traceability and data isolation are features that facilitate compliance. We recommend consulting your compliance officer for any specific questions.

Initial deployment takes a few days. Ingesting your partners' product sheets and general conditions is quick. The chatbot and phone agent can be operational within a week.

LetzAgents offers plans adapted to all sizes of business. The cost is a flat rate, not per user. Check our pricing for your situation.

No, and that is not the goal. The Private AI accelerates low-value tasks -- CV screening, summary writing, document generation -- so your consultants can focus on what makes the difference: interviews, human assessment, candidate and client relationships. The AI proposes, the consultant decides.

Your LetzAgents instance is hosted in Europe, isolated from other clients. No CV, no personal data passes through American servers or shared models. Data stays under your control, in compliance with the GDPR. This is the fundamental advantage of a Private AI over ChatGPT or other public AIs.

Yes. LetzAgents works natively in French, English, German and Luxembourgish. The AI understands Luxembourg market specificities: cross-border profiles (France, Belgium, Germany), multiple language requirements, work permits, Luxembourg labour legislation. Your knowledge base can include all specific regulations.

Initial deployment takes a few days. Ingesting your existing CV database and document templates is quick. The candidate chatbot and pre-qualification phone agent can be operational within a week. The AI then continuously improves with every new CV and every new mandate.

LetzAgents operates on a per-user licence system. Each consultant has their own licence to access the Private AI. The chatbot and phone agent are billed separately based on interaction volume. Contact us for a quote tailored to your agency's size.

Yes. Luxembourg offers digital transformation grants for SMEs through the Fit4Digital programme. Luxembourg businesses can benefit from government aid of up to 17,500 euros for adopting AI tools. We assist you with the grant application process.

Yes. The AI manages each practitioner's schedule individually. It knows each person's specialities (colourist, aesthetician, masseuse) and directs clients to the right professional based on the requested treatment and availability. If a client asks for a balayage, they'll be directed to your colourist; if they ask for a massage, to your masseuse.

Pricing is per licence (not per user), which means your whole team can benefit for a fixed cost. Luxembourg SMEs can benefit from government aid of up to EUR 17,500 for implementing AI solutions. Contact us for a quote tailored to your size and needs.

Yes. Based on client history (previous treatments, declared preferences, skin type), the chatbot can suggest suitable treatments, combined packages or new offerings. Recommendations remain suggestions only — the client always chooses freely and your team can adjust the proposals.

Allergy and contraindication information is recorded in each client's profile. The AI takes these into account when making recommendations and flags them to the practitioner before each treatment. This sensitive data stays in Europe, in your private instance, in compliance with the GDPR.

Yes. The LetzAgents AI phone agent uses advanced speech synthesis with a warm, professional tone. It can communicate in French, English, German and Luxembourgish. Clients often don't realise they're speaking to an AI. For complex requests, the call is transferred to your team.

Setup takes a few days. We configure the chatbot and phone agent with your treatment menu, pricing and opening hours. Connecting to your scheduling tool is quick. Your salon can be up and running with AI in less than a week.

ChatGPT Enterprise offers a DPA (Data Processing Agreement) and guarantees that your data is not used for training. However, your data still passes through OpenAI's infrastructure in the United States. For companies subject to professional secrecy in Luxembourg or handling health, financial or legal data, this may pose a compliance issue.

Yes. LetzAgents requires no complex technical migration. You provide your internal documents, and the LetzAgents team configures your private instance. There is no data to "export" from ChatGPT, since ChatGPT does not store your knowledge base in a structured way.

LetzAgents uses high-performance AI models hosted in Europe. The model choice is adapted to your use case. The key advantage is not the model itself, but the architecture: a private instance connected to your documents, hosted in your jurisdiction.

ChatGPT Enterprise is charged per user (approximately $60/month/user) without business customization. LetzAgents offers plans adapted to your company size, including document ingestion, local support and sovereign hosting. Check our pricing for a detailed comparison.

On general questions, ChatGPT and LetzAgents offer comparable quality. On questions specific to your company, LetzAgents is clearly superior because it relies on your actual documents. And above all, it cites its sources,something ChatGPT doesn't do for your internal content.

Absolutely. The two solutions address different needs and are complementary. Copilot for daily office tasks within Microsoft 365 (summarising emails, creating presentations), LetzAgents for complex business questions, client support via chatbot and AI phone reception. Many companies use both.

Microsoft offers data residency in Europe on Azure. However, Microsoft remains subject to the US Cloud Act, which can compel the company to disclose data. For regulated professions in Luxembourg, this legal nuance is significant. LetzAgents eliminates this grey area entirely.

No. Copilot only works with data accessible via Microsoft Graph (SharePoint, OneDrive, Outlook, Teams). If your business documentation is in other systems (ERP, accounting software, file server, database), Copilot cannot access it. LetzAgents ingests all formats regardless of their origin.

No, LetzAgents does not integrate natively into Office applications. This is an architectural choice: LetzAgents is an independent tool accessible via the web and an API. If your primary need is an assistant inside Word and Excel, Copilot is better suited. If you need a business AI with a client chatbot and phone agent, LetzAgents is the right choice.

Copilot costs $30/month per user, on top of your M365 licence. For 20 users, that is $600/month without business customisation. LetzAgents offers tailored plans (SME and Enterprise) with pricing on request, including sovereign hosting, document ingestion and local support. Check our pricing for your situation.

Claude is one of the best AI models on the market, that is undeniable. But an AI model alone is just a tool. What makes the difference for a business is the architecture around the model: sovereign hosting, permanent knowledge base, multichannel agents, response traceability. LetzAgents integrates high-performance models into an architecture designed for business. If you are looking for the best individual conversational assistant, Claude is an excellent choice. If you are looking for a business AI with sovereignty and customer agents, LetzAgents better meets that need.

LetzAgents uses high-performance language models hosted in Europe. The choice of model may vary depending on needs and evolve with the market. The key point is that the model runs on sovereign infrastructure, in a dedicated instance for your company,something Claude does not offer.

Claude's Projects allow sharing context between multiple conversations. It is useful but limited in volume (a few documents) and persistence. LetzAgents ingests and indexes your entire document base (thousands of documents) permanently, with real-time semantic search and traceable sources. It is not the same scale.

Technically yes, but this requires significant development, infrastructure management, and data still passes through Anthropic's servers in the United States. LetzAgents offers you all of this turnkey, hosted in Europe, with no development on your side.

Absolutely. Many professionals use Claude for individual tasks (brainstorming, writing, one-off document analysis) and LetzAgents as their business AI with knowledge base, customer chatbot and AI phone agent. The two are complementary.

Technically, DeepSeek models are open source and can be downloaded. But running a model with 671 billion parameters (DeepSeek-V3) in production requires very expensive GPU infrastructure (several hundred thousand euros), advanced technical expertise, and continuous maintenance. Then you would still need to develop the RAG knowledge base, the customer chatbot, the phone agent, etc. LetzAgents offers all of this turnkey.

On certain benchmarks (mathematics, reasoning, code), DeepSeek-R1 does indeed rival the best models on the market. This is a remarkable technical achievement. But the raw performance of a model is only part of the equation for a business. The quality in French lags behind, there is no knowledge base, no customer agents, and GDPR compliance is not ensured.

Using the DeepSeek web interface or API for personal use is not illegal per se. But using the API to process personal data of your customers or employees poses a problem under the GDPR, as data is transferred to China without an adequate legal framework. Several European data protection authorities have already opened investigations.

DeepSeek is funded by High-Flyer, a Chinese quantitative investment fund, and benefits from hardware and energy access conditions specific to the Chinese market. The long-term business model is not yet clear. For a company building its AI strategy for the long term, the sustainability and transparency of the provider are important criteria.

This is possible for compartmentalised uses. For example, your technical team could use DeepSeek self-hosted for development tasks (code, testing) without sensitive data, and LetzAgents for enterprise AI with customer data, chatbot and phone agent. The important thing is not to mix sensitive data with a service whose GDPR compliance is not ensured.

Absolutely. Both solutions address different needs and are complementary. Gemini for daily office tasks within Google Workspace (summarising emails, drafting in Docs, analysing in Sheets), LetzAgents for complex business questions, client support via chatbot and AI phone reception. Many businesses use both.

NotebookLM is an excellent tool for analysing a small number of documents (up to 50 sources per notebook). But it remains an individual tool, tied to your Google account, hosted in the United States. It does not create a shared and permanent enterprise knowledge base, does not offer a client chatbot or phone agent, and does not guarantee sovereign hosting. It is a complementary tool, not a direct competitor to LetzAgents.

No. LetzAgents is independent of your software ecosystem. You can perfectly well use Google Workspace for your daily work and LetzAgents for your enterprise AI, your client chatbot and your phone agent. The two do not conflict.

No, LetzAgents does not integrate natively into Google applications. This is an architectural choice: LetzAgents is an independent tool accessible via the web and an API. If your primary need is an assistant inside Gmail and Google Docs, Gemini is better suited. If your need is a business AI with client chatbot and phone agent, LetzAgents is the right choice.

Gemini for Workspace costs between $20 and $30/month per user, on top of your Google Workspace licence. For 20 users, that is $400 to $600/month. LetzAgents offers tailored plans (SME and Enterprise) with pricing on request, including sovereign hosting, document ingestion and local support. Check our pricing for your situation.

Mistral is indeed a French company, and that is a real asset compared to OpenAI or Google. But sovereignty is not limited to the company's nationality. Mistral distributes its models via Azure (Microsoft) and AWS (Amazon). The API infrastructure is shared. And there is no dedicated instance per client. LetzAgents goes further: 100% European infrastructure, isolated instances, no dependency on any American cloud.

LetzAgents uses high-performance language models hosted in Europe. The choice of model may include Mistral models among others, depending on needs and performance. The key point is that the model runs on sovereign infrastructure, in a dedicated instance.

That is entirely possible if you have the technical team to do it. Building a complete solution around the Mistral API,with RAG, knowledge base, customer chatbot, phone agent, sovereign hosting,represents a significant development investment (several months, several developers). LetzAgents offers you all of this turnkey. It is the difference between buying an engine and buying a car.

Le Chat is a conversational assistant, comparable to ChatGPT or Claude. It is useful for individual tasks (writing, research, analysis). But it does not create an enterprise knowledge base, does not offer a customer chatbot embeddable on your site, does not offer an AI phone agent, and does not guarantee a dedicated instance for your data. These are two very different products.

Of course. Your technical team can use the Mistral API for specific developments, and LetzAgents for enterprise AI with knowledge base, customer chatbot and AI phone agent. The two are complementary: Mistral for developers, LetzAgents for business.
