Xenaxio vs Proton
Proton from Switzerland encrypts mail, calendar and drive end to end, and since 2026 its video calls in Proton Meet too. Its AI Lumo runs on open models on servers Proton controls, as a separate assistant. What the provider cannot read, no AI on the server can search either. Xenaxio lets the AI work in mailbox, calendar, files and chat – under clear rules and with an audit log.

Proton fits better if …
- End-to-end encryption of all emails is a must
- You want a password manager and VPN in the same plan
In detail
Encryption or an assistant in the mailbox
Proton encrypts emails end to end and with zero-access encryption: not even Proton can read them. That is maximum protection – and it means no AI on the server can search your mailbox. Proton’s assistant Lumo runs on open models on servers Proton controls and works as a separate chat. In Xenaxio the assistant reads mail, calendar, files and – if allowed – Rooms, with the rights of the person who asks.
How Xenaxio keeps the AI in check
The assistant reads only what the person may see. It deletes nothing except drafts it saved itself, and only after you confirm; meetings are created only after you confirm; it sends email only for a scheduled task you explicitly allow. Instructions hidden in emails are treated as data. Content is not used for training, and every action is in the audit log. With your own model on your own servers, nothing goes outside at all.
More than mail
Xenaxio brings team chat with channels (Rooms), online booking like Calendly, video meetings and projects next to the mailbox. Proton offers a password manager and VPN in its business plans and, since 2026, end-to-end encrypted video calls with Proton Meet. If end-to-end encryption of every email is a must, Proton or Tuta are the right choice.

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.
Can the AI send or delete emails on its own?
It can delete only drafts it created itself – and only after you confirm; never your own drafts or any other email. The AI writes drafts and proposes meetings; they are created only after you confirm. It may send only for a scheduled task you explicitly allow it to – and only to the addresses you name.
