I strongly support this feature.

I have also submitted a related feature request called "Telegram-style AI Auto-Translate for Proton Mail", which expands this idea by proposing optional automatic AI-powered translation similar to Telegram's translation system.

I believe combining AI-powered, context-aware translations with automatic language detection and user-selectable languages would provide an outstanding user experience while remaining consistent with Proton's privacy-first philosophy.

I would love to see Proton Mail implement an AI-powered translation feature similar to Telegram's excellent automatic translation system.

Telegram has one of the best translation experiences available today. Once enabled in the settings, messages written in foreign languages can be translated effortlessly, making international communication seamless.

I believe Proton Mail could implement a similar feature while staying true to Proton's privacy-first philosophy.

My ideal implementation would include:

• Automatic language detection.
• A setting in Proton Mail where users can enable or disable automatic translation.
• The ability to choose which languages should be translated automatically and which languages should always remain untranslated.
• AI-powered, context-aware translations instead of simple word-for-word translation.
• Incoming emails automatically translated into the user's preferred language without requiring manual action.
• A "Show Original" button to instantly switch back to the original email.
• Optional side-by-side view showing both the original email and the translated version.
• Translation of outgoing emails before sending.
• Privacy-preserving implementation using Proton's own AI infrastructure or on-device processing whenever possible.

For example, I could choose Finnish as my preferred language and configure Proton Mail to automatically translate emails written in English, German, French, Spanish, Japanese, Chinese, and other languages into Finnish as soon as I open them.

This would dramatically improve the user experience for people who communicate internationally while fully respecting Proton's commitment to privacy and security.

I believe this would become one of Proton Mail's most valuable AI-powered features and would clearly distinguish Proton Mail from other secure email providers.

Thank you for considering this suggestion.

Without a translation feature, I won’t fully switch from Gmail.

Yes, it's important because I also work in different languages ​​and it needs to be quick and easy.

I'm a new Proton Mail user and while I appreciate the security, the features that are ignored in the name security are a bit extreme. I struggle to understand how Lumo AI cannot be implemented for simple in email translation.

It's difficult for me to fully switch to Proton mail without auto translation options. However if AI integration will be part of it I will discontinue using Proton mail altogether.

As an artist receiving emails from all over the world, (this week Sweden and Japan) I need a build in translate option. Just copy paste in other apps, doesn't work with layout of emails. (only speak Dutch and English myself)

I used this function weekly in Gmail.

I receive emails in various languages and I can only understand German and English well enough to read them without a translator

Also i am an expat and a large amount of emails i receive are in German. Using the translation extension's in the browser doesn't work properly because my Proton is in english and the content of the email is in German. If i don't see this feature moving soon probably i need to find another email provider unfortunately.

This is the one feature I've been waiting for to start using the desktop app.

I really miss this feature. as an expat living in another country, it's a Gmail feature I used on a daily basis.
being able to display a message as is, translated, rather than having to copy paste it into a separate translator app, is a big deal.

Being able to right click and select translate would be really useful.

I also noticed this feature is not available. Just got an email in swedish and couldnt find translate option!

Simultaneous email translation is a critical and basic feature that should already exist in Proton Mail

I would love to see a translate feature in Proton mail as an addon or a separate tool, a secure and private alternative to Google Translate!

Gmail has a really nice feature where you can simply click on "Translate to English" if the content of the e-mail is in another language, which is really useful.

As a person who moved to a different country and still learning the native language, receiving e-mails from public authorities or doctor, etc., in a foreign language and having to go back and forth from e-mail to a translate app can be a hassle so it would be really nice and useful to have this feature.

This would be a VERY nice feature. I travel a lot and get emails in many different languages. Now the only way to translate is use chrome and your web client.

We need to have a translation option within Proton Mail!

Email translations (don't care for AI) would be really helpful.

It would be convenient if there was a translator that could translate text from one language to another inside the mail client.

I explicitly do not want integrated AI (negative utility in its current state, feature bloat, loss of focus on core functionality).

Re: translations, there's no benefit to doing this within Proton Mail versus using translations built into your browser, especially assuming, like Firefox, those translations are private.
