Please please make this opt-in if you do it, I do not want any AI slop in my Proton account. It's one of the few app suites still without it and that's one of the main reasons I intend to stick to Proton and keep paying for a subscription.

For those of us who do not like to use AI and that care about the environment this would be a MAJOR downgrade, to have Lumo use be pushed in other Proton apps... Even if it's not slop and it works well, it HAS TO BE opt-in...

Here's a detailed feature request that I created for the calendar because I agree, lumo needs to integrate with more. It now integrates with the drive https://protonmail.uservoice.com/forums/284483-proton-mail-calendar/suggestions/51202936-enable-calendar-writing-for-lumo

I love what Proton is building with Lumo, but there's a gap that's genuinely frustrating in daily use: Lumo can't write to Proton Calendar.

If I want Lumo to add an event, I'm manually exporting, uploading, processing, re-importing. That's not an AI assistant — that's extra homework. For someone with ADHD, that friction might as well be a wall.

Siri and Google Assistant do this every day. They encrypt the event locally on your device before anything touches the cloud — the AI never sees your key. That's not magic, it's just good architecture. Proton already understands local-first encryption better than anyone. So why can't Lumo do the same thing?

What I'm proposing is pretty simple:

1. You tell Lumo to add an event
2. Lumo sends the request to your device
3. Your device encrypts it with your private key
4. Your device sends it to Proton Calendar

Zero-Access stays intact. The keys never leave your device. But the workflow actually works.

This isn't asking Proton to compromise on privacy — it's asking them to finish the job. A private AI assistant that can't write to your calendar isn't a full assistant. Let's fix that.

"Currently Lumo has access to your Proton Drive and you can provide it files. I would like Lumo to also have access to Proton Docs, so it could use context in those docs to help form answers. Ideally if Lumo was accessible in Proton Docs to help draft documents it would be a big win." <--- I really miss this feature in Proton Docs too, especially when you want to work creatively. At the very least, I’d like to be able to link it to Lumo AI within the project so it’s always up to date. If Proton Drive could work together with Proton Docs, plus the integration with Lumo AI, that would be enough for me personally as an optional feature. Because I like to write a book or something like that, and at the moment it’s extremely unintuitive and cumbersome for me to manage. Although I’m a free user, I’d love to see this available for all users, so that I can actually work on the document, whether online or offline, with everything always kept up to date for the project.

I’d also welcome it if more file formats were supported besides Markdown; that way, I could switch over from Google completely.

The final thing I’m missing is simply being able to work with Proton Docs within Proton Drive itself; so far, that’s not possible at all. I’d also be happy if Proton Docs were available as a file format. I haven’t seen this yet, but then I could carry on writing on the go via my mobile phone or when I don’t feel like sitting at the PC.

Generally speaking, I think Proton is a good idea, but as you can see, there’s still plenty of room for improvement.

as long as it is opt-in, I wouldn't mind that being a feature, but no shoving it in our faces like google please

I like the idea of being able to, in plain English, ask a locally running AI agent to schedule a meeting, or submit feedback, or a bug report, all within the privacy of the Proton ecosystem. Not force people to use it, but have it as an option to make life just a little bit easier while still preserving privacy.

This way productivity is increased, life is a little easier, but privacy is not a problem as it's running locally hooked into the E2E encrypted data that the locally running mail and calendar apps already are.

Just use literally any other document service instead of ruining the one good one. If you want AI implemented into everything you're doing, you clearly do not care about data integrity or privacy anyway, so why even bother with Proton?

I'm so tired of AI being forced into everything I do. That's the reason I got started on Proton in the first place, so if this is implemented it'll be an immediate account deletion for me.

Absolutely not. The whole reason I finally went through the hassle of importing all of my Google Sheets to Proton Sheets is because their stupid AI button has now appeared in Sheets, and it was the last straw in a line of many for me. It's bad enough that Proton has bought into the Slop Business, if I get it forced down my throat in my documents and sheets here too I'm once again grabbing all my stuff and leaving.

That would be way worse. No. I don’t want AI in all my proton apps. It’s bad enough that I’m allowing myself to use proton in the first place, knowing proton supports AI.

I think don't doing this will let proton suite lagging behind. This is on a the critical use case when need. I am working with claude workspace personally and the usage is huge, sort and reorganize your data, your mail, massive rename your photos or doc, delegate complexe administrative tasks based on email request including document preparation and retreiving... But... back to my full proton ecosystem everything is lock down. Honestly it is fine because it is the Proton DNA to put security first, and i can understand that you may don't want allow users to API/MCP request their own data, even if we can argue, fine. But since you have devopped Lumo and launch yourself in the AI market why could you not offer the possibility to your dear users to just levrage lumo accross proton suite (at least mail, calendar and drive). Otherwise Lumo is already dead and proposing to answer the 0,1% use case of what AI is proposing. And if you want to truely propose something big, add automation trigger on proton's event (receiving an email, reaching calender event, new file uploded in drive etc...) in a very user friendly and embeded in proton ecosystem and then the value you propose will rocket to the next level. (And sure you should put this behind opt-in option to safeguard the most conservativ users).

This is a no brainer given all of Proton's products. I actually would take it one or two steps further and suggest an actual Agentic AI platform version of Lumo that can reason and adapt and use tools to do things for you. Both online and offline. Now that would be amazing!

Not by default, only through opt- in and under strict privacy criteria it can absolutelyy be an improvement. It was a big plus in Copliot, but I don't trust Microsoft. You can do this the right way.

Do you care about the enviornment, at all? Because if you widen the scope of Lumo then that will need more training data and data centers, to hold that data, I do not want that and hopefully you don't either.

NO! Please no! I can't go back, I cant think about using google except purple😢 Next you will say "Hey can Proton AG go public?"

If this was to be implemented, it should be completely Opt-In, *NOT* enabled by default.

Please, make this available at the users option.
- user opt in - perhaps per chat like enabling web search
- make it possible to view proton document file types as well! I understand that NOT using it is the most secure, but being able to give access to a proton document on proton drive is far more secure than, creating a document with some other, at best, local app, and then uploading it to Lumo.

Please, don't. And, if you do, then thru a plugin that must be explicitly installed.

Lumo being able to help me find emails, calendar items, photos and more would be very helpful. As long as the data behind that is kept user side. Obviously a lot of us have privacy concerns with the request, but if anyone can do it ethically, I hope it would be Proton.

This is a great suggestion and feels like a natural evolution of the Proton ecosystem. Integrating Lumo into Mail could make drafting and refining emails much more efficient. Calendar integration would also be useful for creating and organizing events with less manual effort. Extending this functionality to Drive could help with truthcalulator.com document summaries and content creation. As long as privacy remains a priority, this kind of integration could significantly improve productivity. It would be exciting to see Proton explore this direction in future updates.

This is a really thoughtful idea. Integrating Lumo across Proton’s ecosystem could make everyday tasks much smoother, especially for composing emails or organizing calendars more efficiently. It would add real value without disrupting the privacy-first approach Proton is known for. Hopefully the team considers this kind of cross-app thefrlegendsapks.com functionality in future updates it feels like a natural next step.
