As a privacy-conscious user, I chose the Unlimited plan precisely because it offers robust features without the need to share my account with others. Most privacy-first individuals would likely stick to the Unlimited plan rather than opt for the Duo plan, which is more suitable for those sharing with a family member or second user. It seems unfair that solo users, like myself, are now excluded from accessing the Proton Scribe writing assistant. Proton has always stood for privacy and fairness, and this decision feels like a step away from that. Please consider making this feature available to those of us on the Unlimited plan who prefer to manage our accounts independently.

As someone who actually voted for this feature in the user survey, and finds this technology helpful, I'm also very disappointed by this decision. I'm not sure what the Proton team's understanding of the word "unlimited" is, but I am certainly not paying for Duo or any other package just for this feature which is first only available in Mail, and second not something that I would even use each time I need to send a message anyway. Your support in this request is appreciated.

I am editing this comment to let other users know that I in fact do have access to Scribe on the Unlimited plan, at least for now. You can see the button for it in the Mail composition window, and it does seem to be working even though it isn't listed in the plan option details. Looking forward to testing it out and possibly other features like tab-completion or Scribe for Docs.

I second this. I don't have a need for a duo or family account, and I thought that by subscribing to Proton Unlimited, I would have access to proton's entire suite of products and features (Excluding those which only a business would need).

Also although Proton mentions that the model is open source, is the data which that model was trained on ethically collected with permission/from public domain works. Or was it trained from technically public (but still privacy intrusive to scrape) social media posts like every other LLM?

Either way, I have a bad feeling about the future of Proton. As scribe having been introduced to businesses, family, and duo account subscribers (despite being applicable to Unlimited users too, regardless of what a survey says), plus the inclusion of a model with an unknown (or at least unwilling to share) training dataset sets a bad precedent. If we let this go on without some kind of acknowledgement or explanation from Proton, I genuinely fear we'll be boiled slowly.
