On October 29, 2026, 404 Media published an investigation into how Proton is adopting AI-assisted coding internally. It drew on interviews with current and former employees, internal chats, and an internal engineering memo. The reporting described pressure on engineers to rely on AI tools and a disagreement over additional security testing before release.
Proton responded publicly. On November 1, CTO Bart Butler published the internal memo ("AI @ Proton, Engineering Manifesto"), and Proton apologized, saying it had not met the standards customers should expect. Proton stated that AI use will not come at the expense of security, that it does not install software to track employees' AI-generated code, that no jobs will be cut over AI re-interviews, and that it will publish how it runs code and security reviews.
Users on Proton's feedback forum and on Reddit have discussed the reporting, and some say they are reviewing their subscriptions. Whether you stay or move is your call. If you are comparing options, the questions below help.
What are you actually using Proton for?
Proton covers several jobs. It helps to separate them:
- Your mailbox. Where your email is stored. European options include Tuta and mailbox.org, alongside Proton Mail.
- Your AI assistant. Where you ask questions, draft text, and work with documents. Lumo is Proton's assistant. Wysor is a private AI workspace with several leading models, EU hosting, and contractual zero data retention.
- AI on your email. Help triaging the inbox and drafting replies. Wysor connects to Gmail, Outlook, and any IMAP mailbox, so it works with the provider you choose.
A common setup is a European mailbox for storage plus Wysor for AI and email assistance. You can try Wysor on the free plan before you change anything else.

Wysor is a private AI workspace built in Germany. It brings together several leading models (GPT-5, Claude, Gemini, Perplexity, DeepSeek, and Mistral), and adds AI email management for Gmail, Outlook, and any IMAP mailbox, on-device voice transcription, knowledge-base agents, and research databanks over verified legal and medical sources.

No. Wysor does not host your mailbox. It connects to the mailbox you already use, such as Gmail, Outlook, or any IMAP provider (for example mailbox.org or Posteo), and adds private AI on top: prioritizing your inbox, drafting replies in your tone, and briefing you on contacts. If you want a new encrypted mailbox, pair a European provider with Wysor.
