NO, never. This is our absolute commitment. Kestya operates in a compartmentalized architecture ("Silos"). Your documents are indexed in a private space that belongs exclusively to you. Neither we, nor Mistral, nor any third party has access to your data to train global models.
Your data is stored and processed exclusively in Europe. No data passes through the United States, guaranteeing you total immunity from the American Cloud Act and strict GDPR compliance.
Through strict service compartmentalization. No need to manage complex IT rights. In Kestya, you simply create services then folders (e.g., "HR Folder", "Urban Planning Folder") and define which agents have access. You maintain total and manual control over who sees what.
Thanks to the "Expiration Date". This is a Kestya exclusive. When you add a document or URL, you can assign it a validity date. Once the date passes, the source is automatically disabled or flagged. The AI will never respond to a citizen or agent with an outdated regulation.
Kestya uses a single AI model, the European Mistral. Kestya's value is not the model, it is the RAG architecture we built around it. It explores your documents, retrieves the right information and verifies what the model returns. Your data is processed in Europe, end to end.
It's the difference between an "Engine" and a "Car". ChatGPT and Mistral are raw intelligence engines (conversation). Kestya is complete management software built around these engines. We add everything that classic chats lack for teamwork. Rights management, data security, expiration alerts, the public widget for your website...
It's an intelligent search bar for your website (City Hall, School, Company). It's included in all our offers. We provide you with a small piece of code to copy-paste on your site, and it responds to citizens and customers 24/7 with your official information, drastically reducing calls to your reception.
It's simple and predictable. We offer fixed subscriptions adapted to the size of your organization (Pro Admin or Education). No hidden costs, no complex "token" billing. You control your budget.
Yes, for 7 days. You have access to all features to import your documents and test the relevance of responses. You can cancel at any time with just one click.
It's zero technical. There's no complex connector to install on your servers. Kestya works like a secure USB key in the Cloud (stored and processed exclusively in Europe, at Scaleway). Drag and drop your files (PDF, Word, Excel) directly into the interface. Copy-paste the URLs of websites you want to index. That's it.
