Big supporter of this!^

Being able to ask an AI assistant questions about my inbox — "summarize unread emails," "find the invoice from last month," "draft a reply to this thread" — is genuinely one of the highest-value AI use cases, and I've built daily habits around this capability with other AI products.

Here's why I'd switch those habits entirely to Lumo if this existed:

Privacy as the differentiator. Right now, if I want AI-powered email insights, I have to grant access to services that don't prioritize privacy the way Proton does. An email integration built into Lumo — with the same zero-access, end-to-end encryption philosophy that protects my mail today — would let me completely disconnect from those other AIs. Privacy-preserving email AI is something only Proton can credibly offer, and it would be a genuine differentiator rather than a parity feature.

Suggested privacy safeguards (to keep it consistent with Proton's values):

Explicit opt-in, scoped permissions (read-only by default, per-conversation grants)
Lumo processes only the emails relevant to a query and discards them after the response, consistent with how the existing knowledge base and Drive integration work
Easy auditability of what was shared
Why it's worth building: This is a habit-forming daily-use feature. Once I rely on an assistant for email triage, switching costs are high — which makes it a strong retention driver and a natural reason for users on other AI platforms to migrate to Lumo entirely.

Thank you for building Lumo. I'd happily move my entire AI workflow over if email integration existed.

Just want to add my vote for implementing a way for Lumo to access my accounts products. Specifically today, I would like to access the Proton Calendar, but I definitely see the value in accessing my mails or sheets or similar in the future. Thanks for amazing products!

It would also be great if the Scribe feature were available on the Unlimited plan, since it's currently limited to Duo+ subscriptions. As of right now, I just open Lumo in a browser tab instead and get the same result for free, even though I'm already paying for Unlimited :/. It's just unnecessary friction the AI gets used one way or another.

Sorry for the rage Lumo team... I'm here because I care and because I am cheering for you!

I love the IDEA of Lumo being a truly private AI assistant, but why can't it read Proton's OWN FILE TYPES?? I have to export Proton Docs and Proton Sheets so Lumo can work with them! WHY?

Really need the ability to ask questions about my emails

As a temporary solution, being able to tag certain emails in ProtonMail to be accessible by Lumo would be very useful. The system could create a shadow copy in ProtonDrive which could then be accessible to Lumo.

Alternatively, a button in ProtonMail that allows me to export a single email or an email thread to a Lumo project would also be helpful. At the moment I need to copy and paste the email text to Lumo - and this has its own quirks/inefficiencies.

Projects aren't nearly as useful without this feature. Read and write proton drive. Inbox processing.

Unfortunately and also fortunately Proton doesn't have the big business funding to get things moving the way google and perplexity do. My bet is Proton is looking at this one though. Give us the peace of mind to know you are Proton people!

Sadly, there is no official confirmation from Proton despite this being the top suggestion for Lumo. Once my subscription expires, I will not renew it if this is not implemented. Calendar integration is especially vital to me.

Let's face it: The underlying models are not really that good when it comes to complex thinking tasks. The untapped unrivaled potential for Lumo is the integration with the rest of the suite with privacy in mind.

Please, make this a priority, or at least let us know if there are plans for doing this other than the usual "we are exploring options" marketing buzzwords... Instead of focusing on stuff the users want, they give us useless features like subpar-quality image generation.

Drive especially!! (Save to Drive)

I would like Lumo being able to access (read/write) content in selected proton apps. Example: Lumo reads e-mail (protonmail) and writes information to calendar or sheets. That would enhance skills of Lumo for producing work results across the proton apps.

Great idea! Especially if Lumo+ remains available and Optional, and clearly visible, not just a simple toggle switch, would be "convenient" privacy, and efficient!

Please add an official ChatGPT / AI assistant integration for Proton Mail.

The integration should allow users to:
• securely read emails (with permission);
• summarize inboxes;
• draft replies;
• create drafts without sending;
• assist with job applications and business communication.

Security requirements:
• OAuth authentication;
• user-controlled permissions;
• read-only mode;
• draft-only mode;
• no automatic sending without confirmation;
• audit log of AI actions.

This would make Proton Mail the best privacy-focused email service for professionals, founders, developers and business users who rely on AI.

For a Lumo+ subscription to be worth even considering, it must be able to write files to Proton Drive, ideally through some MCP. It's almost worthless to me without.

This was the only reason I got Lumo and I just found out it can't scan my mailbox. I struggle to find any use of the AI feature if it can't do that!

Request for better Lumo image support + more flexible bundling for existing customers

I’m a long-time Proton user with multiple services (including Unlimited). I love the privacy focus of Lumo, but I’m frustrated by the ongoing lack of reliable image/PDF screenshot support (JPG, PNG, Snagit exports, etc.). This was promised in the 2025 roadmap but still doesn’t work consistently, even via Proton Drive.
Additionally, as an existing paid customer, the lack of meaningful discounts or flexible bundling for Lumo Plus feels unfair. Many of us would prefer the ability to build our own packages rather than being pushed into full bundles.
Please prioritize:

Full image upload + vision analysis (including screenshots and embedded PDFs).
Better loyalty pricing for long-term customers.
More customizable service bundles.

Thank you for building privacy-first tools — these improvements would make Lumo a true daily driver for professional work like contract review and HR documentation.

LLM is for automation and I'm here for it. My current workflow is simple.

My client sent a message to book a session with me. I paste that message and Claude will create an .ics file for me to download. I then will import it into my Proton Calendar. As for Lumo, I would have to go for a few more steps of manually creating, copying, pasting and converting files. Granted that it is only a few more clicks, but it would be nice that Lumo can do that with just one chat and ask for my approval just like Gemini did with Google's workflow.

My suggestion if executed would look like this example below:

"Hey Lumo, add these events to my Work calendar. </insert messages or pictures of said events>"

"Sure! Here's your events added. <2 buttons "Approve" "Cancel">"

It is only an importing job, so I see no possible privacy exploit here. You should also be able to tick which calendar you wanna share to Lumo.

That’s actually a great idea—having Lumo built into Mail, Calendar, and Drive would make it way more useful day-to-day. Being able to draft emails, summarize threads, or auto-create events directly inside the apps would save a lot of time and reduce context switching.

If done with strong privacy (which Proton is known for), this could be a big upgrade to their ecosystem.

I like how integrated tools improve workflow—similar to how platforms like **pvzfusionapk** keep everything streamlined and easy to access in one place. https://pvzfusionapk.mx/

Not only proton apps.

I want to control OTHER apps on my iPhone with Lumo too.
Like:
Calendar, Home app, Notes, the Clock (like alarms), Mail, Messages, Spotify, Audible.

.

And yes, those features definatelly should be OptIn per App.
