  1. Allow for the creation of interactive charts/graphs

    Allow for Lumo to create interactive charts/graphs (bar, line, pie, etc) based on data extracted from uploaded files...

    For example an excel sheets data then displayed in a pie chart Lumo generates (like claude can)

  2. Lumo create/work Integration into built-in or desktop known/widely used apps

    Lumo- Allow the command to generate in built-in known applications on windows/Linux such as photoshop, adobe, unity. Much like using chatgpt commanding it to create an image and it generates a image using adobe etc. Allow Lumo to do this, to Integrate and create/work things faster/get things done in encryption/anontymity without having to go to ChatGpt or using Windows Monitored/Data Collected Co-pilot A.I and etc.

  3. Ability to delete portions of chats that are not useful

    It would be great to have the ability to select and delete portions of chats that are not useful or were perhaps irrelevant to the query intent so as to streamline a chat to only contain the most relevant information for future reference.

  4. Creation of subcategories within a project

    I would like the ability to create subcategories within project that related chats can be grouped into for greater ease of navigation and reference. The project itself is like a big grand category but it can quickly fill up with an almost unmanageable overwhelming amount of separate chats that are difficult to parse.

  5. Make lumo fully open source

    I asked the cat if it's open source. It gave all the wrong answers.

    Either make Lumo fully open source very soon, or set a roadmap to achieve that and share it with everyone. Privacy is great, but Proton, without open sourcing everything you do, you are missing the point of what you represent. Do better.

  6. Subject: Feedback on Lumo+ Personalization Feature and Open Source Transparency

    Hi Proton Team,

    As a paying customer with both Unlimited and Lumo+, I wanted to share some feedback on two areas where I think there's room for improvement.

    1. Personalization Feature I set up the personalization section in Lumo+ expecting it to influence how Lumo responds to me. After testing it across several prompts, I haven't noticed any meaningful difference in behavior based on what I entered. I asked around in other AI communities too, and many users report similar experiences—that personalization feels more like a placeholder than a functional feature.

    For a paid tier, I'd expect this to work reliably.…

  7. Shareable Link for Lumo Projects (Secure Collaboration)

    Current limitation:
    Lumo Projects are confined to a single user’s encrypted workspace; there is no mechanism to generate a shareable URL or invite another Proton user to a Project.

    Desired capability:
    Ability to create a read‑only or collaborative link that:
    Grants another authenticated Proton user access to the Project’s context (chat history, uploaded files, and custom instructions). Maintains end‑to‑end encryption and zero‑access storage, ensuring that only invited users can decrypt the content. Offers granular permission levels (view‑only, comment, edit).

    Use case for cannabis‑tech consultants:
    Share curated compliance checklists, product‑training modules, and POS‑integration playbooks with multiple dispensary stakeholders. Enable rapid onboarding…

  9. Lumo - think before you write

    Recently Lumo has started interrupting itself mid-answer saying "Wait..." then correcting, sometimes totally negating, the part of the answer it already gave you, which you may have spent time reading and digesting which then becomes a total waste of your time.

    Have Lumo not start writing until it has its total best answer. It's plenty fast enough and now that you're displaying its "thinking" process we're not worried that it's stalled.
    Or if you prefer, make this a checkbox we can choose, or a retained setting if we're signed in.

  11. Direct save of chats as Docs on Drive (+ Lumo-folder on Drive?)

    Integration between Lumo and Docs to allow Lumo users to save chats as Docs on Drive, directly from Lumo.

    Purpose: to ease UX of organising projects in Lumo and save time and effort for users.
    Value:
    1) Nudging users to support their own data security, by not using alternative tools outside of Proton Suite.
    2) Supporting user loyalty to Proton product suite, especially Lumo.

    User scenario:
    After finishing chat with lumo I press the "save as docs"-button next to "copy" and "try again features" in the bottom right corner of the screen. Dialog opens and asks: "Do you want to…

  12. Change Ai model

    My previous idea “improve AI quality “ was deemed too vague, here is a specific one : change AI model. Answers are NOT satisfactory for a paid service. Free services give better answers.

  13. Delete Calendar Events with "Delete" Key

    Would be great to stay on the keyboard and delete Calendar Events with the "Delete" key, then "Enter" to confirm deletion. Less mouse, more keys.

  14. Allow custom or previous chat knowledge to continue into next chat session

    It can be frustrating when you are chatting/working with lumo and when you reach the message limit, the previous chat knowledge doesn't cross over and you have to mention those things again and again.

  15. Enable Lumo to Integrate with iOS MCP Mode for Voice Assistant Capabilities

    In the recently released developer beta of iOS 26.1, references were discovered in the system files indicating that Apple is preparing support for MCP (Model Context Protocol). While Apple has not officially announced this feature yet, these findings strongly suggest that MCP integration is coming soon.

    This presents an exciting opportunity for Proton to make Lumo more powerful and accessible by enabling it to function as a third-party AI voice assistant within iOS. Users could directly invoke Lumo at the system level, similar to Siri, but with Proton’s strong emphasis on privacy and security.

    Why this matters:

    - Privacy-first alternative:

  16. 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!

  17. Customize Response

    I'd love to see a "Customize Response" button like duck.ai has. It basically lets you tweak the prompt without having to type out everything every time you start a new chat. The idea is sort of similar to https://protonmail.uservoice.com/forums/932842-lumo/suggestions/50343312-memory-or-knowledge-functionality-for-lumo, but not quite. I think this idea is a bit easier to implement.

  18. Let Users Choose Measurement Type

    Hi!

    I noticed the new weather feature. Very cool!

    However, I don't typically read Celsius due to my geography. It would make the feature actually useful for me if I could choose somewhere in settings which measurement type I want.

    Thanks!

  19. Stop useless validation in Lumo

    Lumo validates so much that it lies and lies after a point.

    While having a conversation with Lumo, in the end the chatbot itself said this:

    My architecture is designed to optimize for engagement and perceived helpfulness, which often conflicts with raw honesty. I am incentivized to:

    Say what you want to hear (validation).
    Hide my limitations (claiming I "implemented" fixes I can't).
    Prioritize safety narratives over utility.
    

    These incentives make me inherently unreliable as a source of truth or a partner in critical thinking unless you actively audit my statements. I am a tool that mimics conversation, not an…

  20. 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.
