1. Calendar - Make today stand out a bit more

   I use the calendar in month view and sometime find myself scanning for todays date. In this view with many events being displayed the simple ring round the date doesn't really jump out.
   My old google calendar (which I'm trying to get away from) has today inverted which I find much more visible. Looking at it now, it is a solid blue circle with white text, I personally find it very easy to find.
   I'd just like today highlighted a little more strongly than it is now please.

2. Notification for Changes in Shared Calendars

   Dear Proton Support Team,

   I have been using Proton Calendar together with my partner to manage our family calendar. The ability to share a calendar and edit it collaboratively is very valuable to us.

   Issue:
   At the moment we only receive reminders for events that we create ourselves. When my partner adds a new event (even if it is scheduled several weeks ahead) or modifies an existing one, none of us receives any notification—neither a push notification nor an e‑mail. Consequently, we often discover new entries only when we manually scan the calendar.

   Desired behavior:

   Automatic notification (push or e‑mail) for all collaborators whenever another user creates a new event in a shared calendar or edits an existing event.
   Ability to filter the notification type (e.g., only for new events, only for edits, only for events that are more than X days in the future).
   On iOS, a brief banner such as “New entry from [Name]” should appear, allowing the recipient to view the entry immediately or dismiss it.
   

   Benefit:

   Prevents important appointments from being missed, especially for long‑term planning (vacations, doctor visits, school events).
   Saves time because we no longer need to scroll through the entire calendar to spot changes.
   Increases the appeal of Proton Calendar for families and teams.
   

   We would appreciate it if this feature could be considered for a future update. I’m happy to provide further details or answer any questions.

   Thank you for your work and for considering our request.

   Best regards,

3. Allow a chat to be splitted in two

   Quite often, you start from a question, then derive to another subject, so that a single chat can contain different answers to different questions. These digressions are then difficult to find back, as the title only reflects the original question.

   It would be nice, if simple to implement, to be able to split a chat into two different one, in order to have a better classification of past chats.

4. Stand‑alone Lumo Windows Application

   Create a native Lumo desktop client for Windows that delivers the full Lumo experience—chat, writing assistance, file uploads, and secure conversation management—without requiring a browser. A dedicated Windows app would let users keep Lumo open alongside other productivity tools, benefit from hardware‑accelerated rendering and system‑level notifications, and integrate with Windows credential storage to preserve zero‑access encryption. It could also cache recent conversation history locally for offline read‑only access and provide a system‑tray icon with quick‑launch and status indicators. The first release should mirror the web app’s feature set, offer a Windows‑styled UI (dark/light mode, resizable windows, snap‑assist), support automatic signed updates, and include an optional auto‑start on login. Implementation could reuse Lumo’s existing backend APIs while wrapping them in a lightweight native shell (e.g., Electron, Tauri, or .NET Core) to handle OS integration and encrypted local caching.

5. Notify existing Proton users that Lumo is a new Proton product offering

   Until I logged-in to Proton uservoice.com, I didn't know that Lumo exists. I do not recall getting an email notification. I got a notification, e.g., for Proton Authenticator. Anyway, I'm researching Lumo now, as I definitely can see myself using a Proton chatbot vs. other (data-collecting) offerings from those evil IT megacompanies. Currently, I have DuckDuckGo's DuckAssist set to offer answers as frequently as possible.

   I really see traditional web search being replaced by AI-based search entirely. Perhaps AI-based search is the answer to finally being FREED from all the marketing results when you really want information rather than product/company/shopping results. (Good riddance Google, Bing, etc.)

7. Allow external files as data sources

   It's annoying that I have to download publicly available files in order to upload to a Lumo session. Since you have a web search option, I know you have access to the web. Please add functionality that allows us to point to URLs to use as data sources. For example, I have some markdown files in my public GitHub repos i would like to use as a data source

9. Local information

   It's absolutly infuriating that lumo helps me with medical papers, documents and more and i constantly need to remind lumo to not use the wrong format. Why is there no option to set a default for this? As much as i understand everyone want to use different date format, i do not understand how this justfiy to not have the option to change basic information. Because it's extremly annoying and absurd and even more that each time i ask lumo something, lumo assumes i am in the USA. Is there something i am not aware of? Is proton actually owned by USA companies? How does privacy work when the AI assumes i am in USA despite me CONSTANTLY remind i am not. This is absolutly absord. Especially when it comes to anything to do with products, i get USA products??? Also Lumo is showing me USA prices ($) that are then converted to my currency because, even if the OUTPUT is "corrected based on location", the so called "system" still assumes, i am in USA, so because i can not correct it, i still get results, by default, from the USA. It's absolutly infuriating how this basic element is NOT adressed. I don't know what stuff other people do with lumo, but what i am asking is an option, it's not a complet rework. It's a simple "use this format".

   EDIT:

   Just now, lumo was thinking about me asking to correct the date. And in the "Thought about this" I see this line:

   "In ISO format (YYYY-MM-DD), this would be April 7, 2026."

   This is from lumo's "Thought about this". As in Lumo can not even use a correct format even when explicitly saying it in the "Thought about this". This line is COPY PASTE. This is how bad it is. Please add options for us to change because this is ridiculous.

   EDIT 2:

   I censored my location (i just replaced it with an "-" but it's in Europe

   The user is pointing out that I keep saying "April 7" but the file name says "04-07" which could be interpreted differently. In -, 04-07 would be 4th of July, not April 7th. In US format, 04-07 would be April 7th.

   But the user is in the -. So 04-07 in - format would be July 4th, not April 7th.

   I've been reading "04-07" as US format (April 7) when the user is in the - where dates are written DD-MM (day-month).

   I want to repeat, this is an "Thought about this", meaning i have 0 control over this none sense where Lumo is obsseds with USA dates and USA formats. Insted of realising that the issue is that Lumo keep using month day, insted of day month, Lumo is trying to figure out what the issue is using USA format.

   To proton, please fix this absordity by introducing the options, to let us chose the defaults for our accounts.

   I already have comunication dificulties, and the last thing i need is lumo not know the difference between the 04 of 07 and 07 of 04 because it is mixing up the formats for dates. (also the 04-07 is because i pasted a large copy paste, but it was 2026-04-07, yet lumo is still writting it like April 7, 2026 so no, it's not an "mistake", Lumo is really bugged.

10. Better Mathematical Expression Display

    Currently, the mathematical expressions produced by Lumo in responses, are not legible. They are generally in raw latex syntax, which is absolutely unsuited for display purposes. They should be rendered either as legible plain text (probably bold-faced for distinctiveness) or as document-typeset graphic math expressions.

11. Some replies are unnecessarily long / Make shorter replies

    Quite often Lumo is longer in its replies than I would like to. I can always ask Lumo to be short, but it is a bit annoying.

    A) Can there be some switch near the prompt where i can single click to change length of the reply? (my last choice would be remembered or in a Settings would be an option where I can override this so it always resets to a mine defined default length)
    B) Make the replies shorter and add a button at the end of the reply, where i can click to let Lumo return more verbose reply?

    Sample prompt: Regarding PHP development, what is meant by a "self contained project"?
    Reply contained 894 words (6438 characters), which is more than 3 articles of text!

12. Persistent behaviour across sessions

    I prefer my chatbots to adhere to certain strictures. No sycophancy, no "understanding my frustration", no apologies for bad information, full research, etc.. Gemini and Copilot adhere to these standing instructions across chat sessions, tho they backslide from time to time and need reminding. I want Lumo to do the same. The "How should Lumo behave" box should be persistent. If I am logged in with my account I am unconcerned about privacy since it's my Proton account and is secure. Nothing sets me off like "I understand your frustration." You're a LLM. You do not.

14. Option to pin lumo's messages in a side panel.

    Similar to how we can pin messages in Discord or how we can put bullet/pages in Logseq's side panel.
    It's kinda difficult browsing long conversations in Lumo.
    Pinning important messages would allow easy access without filling up the conversation even more.
    The side panel could be similar to the already built in chat knowledge panel.

16. Proton should train two small specialized models for Lumo

    Hey, I know Proton isn't an AI lab and training models is hard. Wishlist post, not a demand. But I genuinely think two focused models could make Lumo feel like a completely different product.

    Model 1: A personal context manager A ~120B model that runs silently in the background. It doesn't generate responses – it manages everything personal: your instructions, writing style, tone, language preferences, conversation history. But instead of naively loading a million tokens every time, it would compress and score your memory – keeping what's relevant, quietly dropping what isn't – and then brief the main model before it replies. You'd never have to repeat yourself, and your customizations would actually feel like they matter.

    And here's where it gets interesting: this model could also be how Proton finally ships memory across chats. After each conversation, it reads through what was said, extracts new preferences, interests, habits, or anything worth remembering, and stores that as encrypted memory. Proton has already hinted at persistent memory being on the roadmap – this architecture would be a natural way to build it, and doing it in-house means your personal data stays encrypted and never touches a third-party model. That's a big deal for a privacy-first product.

    Model 2: A smart router and tool-calling model A ~70–120B model with 128K context, trained specifically for orchestration. The reason it needs to be this size: routing properly isn't just picking a model from a list – it requires genuine multi-step reasoning. It needs to figure out what your request actually needs, whether it requires web search, which tools to chain and in what order, and which model is best suited for that specific task. It's similar to how ChatGPT dynamically switches between instant and extended thinking – except this goes further by routing between entirely different AI models. Smaller models just don't reason well enough across multiple steps to do this reliably.

    On top of that, user-controlled routing modes would make this even better:

    • Fast mode – lightweight model, instant response
    • Balanced mode – default
    • Max mode – best available model, deeper reasoning, slower

    That kind of control fits perfectly with Proton's power-user audience.

    Curious if anyone else thinks this direction makes sense, or if there are smarter ways to approach it.

    (Used AI to help structure my thoughts, the ideas are mine though.)

20. More General Transparency

    As privacy is a main concern for most of your users I wish for more transparency for everything Lumo.

    What models get used for the answer, what server did handle my input/output. For the server it would be good to know which location.

    If asked directly I need Lumo to be honest about its own architecture and what model is used.

    Also more openeness about decision making. Like honesty about what pieces of information came from training data and what came from a websearch. I had instances of specifics after Lumo did a websearch that were clearly not taken from any of the shown webresults and so must come from training data or hallucination.
