  1. 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.

  2. 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

  3. RAG my proton drive. Make Lumo be able to chat with me about my files.

    I bought into Lumo and upgraded my proton drive as I had the impression that I could query my files.
    In fact, I can only upload some of them. Well, some, in fact only 10Mb before it complains. Then if I leave the chat and come back, it seems to have forgotten I uploaded a file to chat with.

    Here is my use case which is currently available in CoPilot.
    1. Have an option for Lumo to chunk and ingest the files in my drive.
    2. Allow me to query them like a proper RAG system

    Thanks.

  5. Add ability to think

    It would be nice to have a "Think" feature like ChatGPT. Doesn't have to be as complete, just letting the model iterate on the solution it is going to give would be nice

  7. Option to start Lumo with voice reconition

    When you want to start lumo with voice reconition. Add the following:

    Hey Lumo "say what you want to say"

    This would be hands free, so you can actually talk to Lumo to open/start it. There would be a button you could press as well.

  8. Dedicated app for Windows

    Create a web wrapper app like proton mail, but for lumo. Instead of having to load lumo in a browser as a tab. Currently this creates issues.

    1: A browser with many tabs will slow lumo down.

    2: Lumo's save ability is tied to the browser's startup behavior. If the browser is set to restore the previous session, then lumo will restore all conversations that are not in ghost mode. If the browser is not set this way, then certain new conversations are not restored when opening the browser. Having ghost mode disabled doesn't make any difference.

    Lumo could have…

  10. Android Intent Support or API for a Reading App Integration

    Dear Lumo Team,
    I'm the developer of @Voice Aloud Reader, a popular Android ebook/document reader app. I'm interested in integrating AI-powered book summarization features that respect user privacy - which makes Lumo an ideal solution.

    Current Approach & Results: I've tested Lumo with book chapters (up to 100KB text) by manually copying/pasting content. The summarization quality and literary analysis are excellent - exactly what my users need for "remind me what happened" scenarios when returning to books after breaks, having questions to answer, discuss the book etc., but copy/paste workflow is far from perfect.

    Feature Requests:
    1. Intent.ACTION_SEND Support: Allow…

  11. 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,…

  12. 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:

  13. Better transparency for Lumo answer - Show Groundedness, Factuality score per answer

    Proton Lumo AI should not only be private, but also fair and transparent about its answers.
    I propose adding simply statistics to each answer derived from the metadata that is already present. E.g. a single bar going from green to red that show the likelihood of an answer being well founded (groundedness score) or something similar to a F1 score. In my opinion this matches the transparency that Proton is providing for all its products. Similar to how Proton uses Open Source code, it should also aim for maximum transparency of Lumo AI answers. This makes Lumo even better than…

  14. Lumo is great at Math, but bad at Latex!

    I am finding that Lumo is shockingly good at the type of math I do, professionally.
    I am seriously thinking about buying the Lumo+ extension.

    However it is very frustrating, at times, by the way it handles Latex in its answers.

    1) Sometime the latex expression is not properly displayed as math, but just as a bunch of code. The latter is of course hard(er) to parse.

    2) When asked to produce latex code, the output is often buggy and contains nonstandard unicode symbols. It rarely compiles out of the box.

    3) When asked to produce small latex code (to…

  15. 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.

  16. 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…

  18. iOS Widget: Please bring back the cat!

    The latest update changed the look and feature of the iOS Widget. It now suggests actions and shows a text instead of Lumo the cat like before.
    I really liked seeing Lumo on my Homescreen. Please bring him/her/it/they back!

  19. 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.

  20. 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.
