from the team:
Hi everyone,
In Proton’s 2024 user survey, it seems like AI usage among the Proton community has now exceeded 50% (it’s at 54% to be exact). It’s 72% if we also count people who are interested in using AI.
Rather than have people use tools like ChatGPT which are horrible for privacy, we’re bridging the gap with Proton Scribe, a privacy-first writing assistant that is built into Proton Mail.
Proton Scribe allows you to generate email drafts based on a prompt and refine with options like shorten, proofread and formalize.
A privacy-first writing assistant
Proton Scribe is a privacy-first take on AI, meaning that it:
- Can be run locally, so your data never leaves your device.
- Does not log or save any of the prompts you input.
- Does not use any of your data for training purposes.
- Is open source, so anyone can inspect and trust the code.
Basically, it’s the privacy-first AI tool that we wish existed, but doesn’t exist, so we built it ourselves. Scribe is not a partnership with a third-party AI firm, it’s developed, run and operated directly by us, based off of open source technologies.
Available now for Visionary, Lifetime, and Business plans
Proton Scribe is available as a paid add-on for business plans, and teams can try it for free. It’s also included for free to all of our legacy Proton Visionary and Lifetime plan subscribers. Learn more about Proton Scribe on our blog: https://proton.me/blog/proton-scribe-writing-assistant
As always, if you have thoughts and comments, let us know.

It sounds like your main concern is that once your inbox is decrypted by your local device it could be used by Proton to train Scribe or for some other (perhaps nefarious) purpose.
For the first point, I think the technical challenge of creating a distributed machine learning algorithm, which runs locally on each user’s device and then somehow aggregates the results, is much more difficult than downloading and using an existing model like Scribe does currently, but I agree that it is theoretically possible. If Proton ever overcomes that challenge and offers that feature, I hope they handle it as I suggested above for Scribe: an option to disable it the first time you use it. As long as I could disable it, I would consider the risk minimal. As it stands today, I consider the risk negligible.
For the second point, it’s true Proton could program their app (or their website) to send your decrypted inbox elsewhere. (That’s true of every email provider, unless sender and receiver have exchanged PGP keys, since email is a plaintext protocol.) I trust that they don’t, based on my assessment of the available info, including discussions like this. I certainly consider them much more trustworthy than Facebook/Meta.
As a general point, I think a lot of security/privacy for services like Proton comes down to trust. It’s important to keep Proton honest and to keep ourselves informed. I’m glad we have communities like this to help us do that.
Sorry I was not claiming that proton in any way was causing a problem here. I was just refuting the point that e2e means they cannot train on your inbox. I don’t even use proton but have been considering it. I do not mind the AI features.
I appreciate you pointing out the limits and pitfalls of e2e encryption. It added important nuance to the thread. Thanks!
You’re welcome. Honestly I wanted to point it out cuz I hate Facebook and WhatsApp 😂
