  1. Dynamically load files from Proton Drive folder instead of file upload

    Please offer the option to point to a folder on Proton Drive. That would be much more flexible instead of uploading new files each time.

  2. public URL parameter that pre‑loads a specific prompt

    It would be nice to have a public URL parameter that pre‑loads a specific prompt, such as https://lumo.proton.me&q=my_specific_prompt because this would make it possible to define "search"-shortcuts in Browsers or for example in krunner under Linux to open Lumo directly with a starting-prompt.

  3. New Project + large information = split in different chats in project

    Since title is self explained let me give an exemple using books.

    When you open a book or anything with an index then you have something that has tons and tons of information. But they have capters (or similar separations) to ensure that it's not to much. And to make it even better, this splits are done based on subjects, themes, arcs, etc, so each chapter is building up the information without it being to much..... except, to understand the title i will talking about books with stories...

    You started the book, you know what it is about (same how…

  4. Lumo Voice Dictation

    I know iOS has voice dictation but this needs to come to the web browser version too. It saves so much time typing and a much better all round experience. Thanks!

  5. Feedback on Conversation Restrictions

    I value Lumo’s privacy-first approach and commitment to respectful dialogue, but I feel that the conversation restrictions and automated content moderation make it frustrating to use for honest adult discussion. Too often, it feels less like I’m talking to a smart assistant and more like I’m conversing with a cautious PR department or a nervous nun—avoiding anything remotely challenging or controversial.

    Real conversation and learning require engagement on sensitive, nuanced topics (like politics, social justice, religion and world affairs). Instead, Lumo shuts down or blocks the session whenever certain keywords or contentious issues are mentioned—even if the conversation is thoughtful,…

  6. Let Lumo export a single answer as PDF file, not as markdown script

    Dear support team, please consider adding the feature to export answers, which are sometimes in form of tables or checklists.

  7. Implement Screen Reader Accessibility Improvements in the Lumo Web and iOS Apps

    As a Lumo user who relies on screen reader technology to access my iPhone, I have several suggestions that would make the Lumo app significantly easier for low vision folks to use. Because it seems the web version of Lumo behaves pretty similarly to the iOS app, I'll focus on the iOS app but do consider these same suggestions for the web app, as well.

    Make prompts and responses into single focusable blocks

    For an example of this, turn on the VoiceOver screen reader in iOS and observe how it behaves in the Facebook iOS app news feed. Although a…

  8. Feature Request: Persistent "Reasoning View" for Transparency & Collaboration

    Hello, Proton.

    Fair notice: I did allow Lumo to aid my crafting of this feedback and suggestion. I thank you folks for all that you do!

    Susana

    To: Lumo Product Team / UX Design From: Susana [User]

    Observation: Following the recent UI update (April 2026), I noticed that Lumo briefly displays a numbered list of internal reasoning steps (e.g., "User is asking X, analyzing data Y") before posting the final response. While this currently disappears quickly, it offers a unique glimpse into the AI's logic.

    Insight: Rather than viewing this as a transient artifact, I believe this "reasoning trace" could…

  9. Voice of the Proton Community app

    DISCLAIMER: It's my ideea but due to going back and forth for hours, i had enough. As such, sorry proton and anyone else, the "corrected version" from Lumo is "wierd" but i hope i make it clear that (sadly for me....) it's still better whatever rambling i wrote. AKA proton or whoever, please ignore any "wording" and just focuse on the idea/suggestion. Since sadly it might not be clear why i suggest this app, aka for everyone to have a (well due to Lumo) have an easier, faster, more accurate, so on and on. Whatever, it's explained so here it…

  10. Python interpreter

    Hi there, I'm a Proton user from around 4–5 years. I consider myself an early adopter of new technologies, so I've been testing out ChatGPT, Gemini, and other variants of LLM chats. One of my main uses of them is as a researcher and engineer, so I want LLM that are robust, in the sense all a LLM can be robust and predictable. But, in the sense, I want a "translator" o a "meta-transpilator" that translate commands into actions to be performed. For example, the task "translate this from Spanish to Catalan", is in fact a direct task that involves…

  12. Humble Suggestion to Enhance the User Experience of Local Processing Mode

    Gratitude and Acknowledgment
    First and foremost, please allow us to express our deepest gratitude to the development team for the excellence already demonstrated in the design of Lumo. The integrated privacy features and the existing Local Mode are a testament to a remarkable commitment to user data protection.

    1. Current Context (Respectful Observation)
      We have observed that switching between Local Mode and Web Mode currently requires navigating through the privacy settings. We fully understand that this design responds to security requirements and clarity of intent, which we commend.

    2. Proposal for Contribution
      In a spirit of collaboration and service to users, we…

  13. Lumo automatic chart resizing

    In a Lumo conversations, charts right columns don't always allow users to read everything in the rectangle.
    Often, users have to scroll right to see all the text and data it contains.
    It can cause some friction when using a regular mouse and an external keyboard without a trackpad.

    If would be nice if Lumo could resize the content so everything reads in a chart without having to scroll right.

  15. Support for bigger Files

    I’m reaching out to request an increase in the maximum file‑upload size.
    The current limit is insufficient for several upcoming projects that involve large assets such as high‑resolution media files, data sets, and compiled binaries.

    None of the models Lumo uses are very good at creative writing. Please add a model that can provide helpful writing critiques, ideas, etc., for creative uses such as storytelling, poetry, songwriting, and creative non-fiction.

  17. Responsive email templates

    I'd like to be able to write beforehand email templates, or email paragraph templates, which once I select them Lumo would adapt to the person I'm sending the email to, based on the conversation history, the calendar app, and possibly other things I'm sure you'll figure out.
    e.g. : I have an appointment confirmation template ; Lumo will automatically adapt the tone, gender, name, date, time, place, etc.

  18. Lumo animated stickers pack

    Hi,

    One of my favorite sticker pack for iMessage (available for other platforms too) is Milk & Mocha bears.
    Now Proton you have just a very cute cat and you did already put a lot of effort in the design and animation.
    I would gladly use Lumo stickers if you can deliver something as nice :-)
    It will also make a good advertising for the product itself: Lumo.

    Thanks for reading / voting.
    Cheers

  19. Suggested Youtube videos were not available

    I asked Lumo to suggest 'best' Youtube videos for a certain topic. It returned with 2 videos, but there were problems.

    1. The first video was fine.
    2. The second video was not longer available on Youtube because the Youtube account had been terminated.
    3. I revised the search and told Lumo the problem, and it suggested 2 more videos.
    4. Of the new videos, the link for the first one was the same as the first one in the previous search, even though it was talking about a totally different video.
    5. The second video in the new search also led to an unavailable…
