  1. Code editor

    It would be nice if the codeblock Lumo uses would be an interactive code editor.
    Right now if I ask Lumo to change part of my code it also tends to rewrite other parts of code which I didnt ask it to do. With an interactive code editor I would be able to select a part of the code and make a prompt just about that selected part. Or I could edit the code myself if I dont like something without having to copy paste the whole code again to Lumo to let it know I edited something. This wouldn't…

  3. download pdf

    recently was using gemini ai pro..they have at top of chat, right corner, "download pdf"..simple and effective. many parts of the world internet is expensive and not available always, this would be useful to user of lumo so they can access chat offline as pdf ( since this is widely used). Any particular reason for not being implemented till now?

  4. Native Excel (.xlsx) editing and export support

    I'd love to see Lumo able to work directly with Excel files — not just reading them, but actually editing them and returning the result as a downloadable .xlsx file.

    My typical use case: I upload a spreadsheet and want Lumo to clean up data, recalculate columns, merge sheets, apply formulas, or reformat cells. Right now, the best I can get back is a markdown table or CSV text that I have to manually copy back into Excel — which is tedious and loses formatting, multiple sheets, and formulas.

    It would be a huge productivity boost if Lumo could:

  5. Lumo Integration to Read Encrypted Emails, Calendar, via On-Device Processing

    I want an AI assistant (Lumo) that can automatically read my Proton Mail inbox and execute actions based on preset rules (e.g., sorting, summarizing, drafting replies, flagging urgent items, consolidating multiple emails into one for review). I understand this requires on-device processing to maintain zero-access encryption. Currently, I have to manually copy/paste emails. An automated, privacy-preserving workflow would be a game-changer for productivity. Lumo needs more gemini like functionality in the Proton product space.

  6. Search not just Lumo chats titles but also content

    The sidebar allows searching in chat titles, but I am unable to easily find on how to search in the chats content (in my questions and Lumo replies). I am aware that i can use browser Ctrl+F to search in current chat, but not in all available chats).

    Ideas:
    - after you type the search query, maybe hitting enter can execute search in content.
    - content search included by default, only the matches in chat titles will be displayed on the top of the search results

    clicking on a content search result, should jump to a correct place in the…

  7. Lumo Scheduling Automation

    I went down the rabbit hole of trying to create a scheduled web search on specifict topics. Lumo repeatedly told me it had automation to do this but when I tried to set it up it ended up apologising each time saying it got a bit excited but can't do what it said it could...
    Functionality request - automation that will run a scheduled task/search/etc

  8. Lumo integration in meet for meeting summaries & transcriptions

    It would be great if the upcoming meet app would have an option to summarize and transcript meetings.
    Making this possible with a trustful AI like Lumo would be amazing (and I think no one else has a meeting transcription feature with a trustful AI)

  9. Ability to edit chat names (especially in projects).

    The automated chat names often aren't relevant to the topic. The ability to edit them would be helpful, especial for projects.

  10. Bring real-time encrypted voice interaction to Lumo using existing MLS/WebRTC infrastructure

    Live Voice Conversation Mode for Lumo — Powered by Proton Meet's Proven Architecture

    Summary: Enable bidirectional voice conversation in Lumo's mobile apps — speak through a Bluetooth headset, receive spoken responses via text-to-speech — creating a Gemini Live-style hands-free experience. Proton Meet already solves the hardest engineering challenges for real-time encrypted audio. Extending this to Lumo is a natural evolution, not a fundamental R&D problem.

    The Opportunity
    Lumo's mobile app supports voice input (speech-to-text) but lacks voice output (text-to-speech) and continuous conversation mode. Users who want hands-free, private AI interaction — while driving, walking, cooking, exercising, or working — have…

  12. Send to Proton Drive Button

    I lost some very important conversations about my ****** cancer journey and important memories because Lumo's local storage was silently cleared despite History being enabled. An automatic export or "Send to Proton Drive" feature would prevent this from happening to others. Memories and Health conversations are too important to lose. Please consider adding automatic backup to Proton Drive or Proton Docs.

  13. allow copying history conversation into the projects that we create.

    currently there isn't an option to copy old chats into new projects. why? this is quite disturbing and prevent us from organizing our old conversations.

  14. Report Carbon equivalent footprint of a user requests

    I think I do not have to explain that energy consumption of LLMs even doing only inférence is high.
    Since Proton has always promoted transparency over source code of its tools, I believe it should also pioneer transparency on this matter.
    There exist libraries to wrap function calls and estimate co2 équivalent (e.g. mlco2)

  15. VSCode integration

    Other LLM's like ChatGPT and Claude have integration with VSCode. It would be great to see an integration for that or another opensource IDE.

    The most amazing thing would be if you can replace all the things most people use day to day with apps and have full support on Linux.

  16. Please add Biometric (fingerprint) unlock to Lumo

    Please add Biometric (fingerprint) unlock to Lumo (and Calendar), it and Calendar seem to be the only Proton apps that do not have this feature.

  17. Feature Request: "Amnesia Bridge" – Cross-Chat Context Retrieval

    When chats close due to resource limits, all invested context is lost. Users must re-upload files and start from scratch—wasting time and compute.

    Proposal: Let users selectively pull context from older chats into active conversations: "Lumo, check our chat from last week for what we found about XY." -> the desired feature is similar to "websearch" - just scoping the own (internal) activities.

    Optional: User tagging of important chats for quicker discovery.

    Why it fits: Same privacy model, just extended. Decryption stays client-side, metadata stays user-controlled and encrypted. No server-side indexing.

    Impact: Better session continuity, no redundant uploads, preserves invested…

  18. Share Lumo Response

    Most other LLM apps have a share icon at the end of a response. When click, a link is generated that points to the response in the conversation. Proton can implement this feature and use the link permissions that exist in Proton Drive. A user could set a default permission policy in the app.

    I use this feature extensively to combat misinformation shared with me by asking Grok, for example, "Is this true?" along with a URL. I then share a link to my AI response result as a source of my research.

  19. Enable Lumo to run locally

    Enable to run Lumo models locally on a computer or laptop, this would enable users to better handle private information, increace speeds (by not needing to have the data travel across the internet continuously) and reduce load on Proton servers.
    This could happen with a standalone app or integrating it with other systems such as LM Studio or Msty Studio

  20. Chat Branching

    Google's Gemini lets you create a branch off of any of the LLM's responses. This allows you to take the conversation in multiple different directions.

    Gemini just creates a new chat for each branch, but I would appreciate if Lumo made the branch chats a child of the original chat for organizational purposes.
