Questions
Can we run Xenaxio on our own servers?
Yes, Xenaxio is built for that from the start: your data centre runs the same software as our cloud, with every feature. With your own AI model, for example through Ollama or vLLM, AI requests stay in your network too. We help with installation and updates – just write to us.
Do we get locked in?
No. Xenaxio uses open standards – IMAP, SMTP, CalDAV, CardDAV and Matrix – and the web client is open source (AGPL). Cloud, cloud with your own model and on-premise are one software, and we handle the move between them.
Is the AI trained on our emails?
No. Your content is not used to train AI models. The AI only reads what your request needs, and every action is recorded in the audit log.
Is Xenaxio open source?
The web client is: it is based on Bulwark Mail and published under AGPL-3.0 on GitHub. We run the platform behind it – administration, AI and the connection to AI chats – for you.
Is there a data processing agreement?
Yes. A data processing agreement under Art. 28 GDPR is available on request to [email protected].
Is there a pilot programme?
Yes. For our first customers we set up Xenaxio personally and move the mailboxes for you; your feedback goes straight into the product. Terms on request.
