  1. Mass calendar deletion

    I want to delete a lot of events in my calendar easily.

    I created recurrent events (6/8 per days). In vacation period, I want to remove these events and replaced them by another ones. For each event, I need to click on the event, click on the delete button and confirm to delete the single event. I would like to select all events on the week and delete them with only one button.

  4. Lumo on Old Phone

    I’m unable to activate dark mode on the Lumo Android app (running on Android 8/Nokia 8); the “Appearance” setting is missing. Even after enabling “Force dark mode” via Developer Options, the app stays bright and the input bar floats in the middle of the screen instead of anchoring to the bottom. It would be great if Lumo provided a functional dark‑mode toggle and proper UI layout for older Android versions, or at least offered a clear fallback/web‑app solution for those devices.

  5. Integrate with Windsurf

    Have Lumo be an available Model via Windsurf like Claude, ChatGPT, Gemini, etc.
    I've found Lumo to be very good with coding example and questions. Having Lumo be able to directly see and edit the code files would be a huge win.

  7. 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:

  8. Lumo needs access to the current date and time

    Having access to the exact current date and time is important for certain tasks. Lumo is able to retrieve the date from its context, but not the time. And it is unable to confirm the date timezone (I assume it is UTC). A tool to fetch the current date and time, and optionally to specify the timezone for which the date and time is requested, would be a helpful feature.

  9. 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?

  10. : Add Read Aloud / Text-to-Speech Button for Responses

    I would like to request a "Read Aloud" button feature for Lumo AI responses. This would allow users to have my replies spoken aloud using text-to-speech.

    Why this would be helpful:

    Great for listening to content while relaxing, resting, or preparing for sleep
    Helpful for accessibility needs (visual impairments or difficulty reading on screen)
    Useful for multitasking when hands are busy but ears are free
    Perfect for consuming longer content like stories, summaries, or articles without staring at a screen
    Suggested implementation:

    A speaker 🔊 button next to each response (or in the response toolbar)
    Ability to pause, resume, and…

  11. Personal assistant

    Would be great if Lumo could take longer tasks, run unattended or on schedule, and interact with mail and drive.
    Like Claude Cowork or Openclaw.

  12. Feedback

    Please make the thumbs up and thumbs down buttons optional.

    Could you put a toggle in settings - to show or hide these feedback buttons?

    I am constantly trying to avoid accidentally clicking on the thumbs up/down…

    It would be really nice if I could just hide them.

    Thanks for Lumo, I love it.

  13. Allow per-project memory with general chat memory disabled

    Enable per-project memory while keeping general chat memory off. This is ideal for users who use general/ghost chats as a scratchpad and want to have memory active only for project chats within their folders.

  14. Automatically save chat responses to a document

    In my view, Lumo 2.0 should prioritize its core strengths—leveraging the scientific and technical expertise behind Proton's mission—rather than focusing heavily on image generation. Image creation requires significant financial investment, and many established competitors already serve this market extensively. While I understand there may be legitimate privacy concerns around processing images, it seems the choice to pursue image generation was driven by market trends in AI rather than staying true to the scientific and educational purpose for which Proton was originally founded. My suggestion would be to refocus development resources toward those foundational goals where Proton has unique value and…

  15. RTL Text Direction Support Request for Lumo UI

    Lumo currently doesn't support right-to-left (RTL) text direction in the UI, neither in the input nor output fields.

    It would be ideal if the app automatically detects and applies the correct text direction based on the first word of each paragraph. For example, if a sentence begins with an English word, it would display left-to-right; if it starts with an Arabic word, it would switch to right-to-left.

    This feature (automatic direction detection) is already implemented in Telegram, and adopting similar functionality would greatly improve the experience for multilingual users.

  16. Language correction button for Lumo with categories

    Add a "Report Language Error" button in the Lumo chat interface that lets users flag language issues directly. After clicking, users choose a category:

    Strict — Pure nonsense/incorrect term. Generates a corrected, academically accurate response.

    Synonym — Suggest an alternative word/phrase and context where it fits better. Helps Lumo understand nuance, register and topic-specific synonyms.

    Humoristic — Witty alternatives and wordplay. Helps Lumo learn humor and puns in the local language (especially useful for users with a "Casual/Cheeky" Lumo personality).

    This feeds into Proton's language improvement pipeline, helping Lumo and Scribe produce more natural, localized output — especially for smaller…

It would be amazing if Lumo could natively view and handle the following formats:.nix configuration files.zip folders and archives.tar.gz archivesAdding support for these formats would make checking files much faster, eliminating the need to download or move them to external apps just to see what is inside.Thank you so much for your…

  19. Subject: User Leaving Due to Lumo v2.0 Image Generation Feature

    I've been a loyal Proton customer across multiple services (Mail, Drive, VPN, Pass, etc.) because I trusted your commitment to privacy-first technology. Unlike other AI providers, Proton was positioned as genuinely different — not collecting data, respecting boundaries, and prioritizing ethics over features.

    The Issue
    Lumo's v2.0 update introduced image generation capabilities. This fundamentally changed what made Lumo trustworthy to users like myself. Before this update, there was one clear distinction between Lumo and mainstream AIs: you didn't offer tools that could be used to create potentially harmful content. Now, that line has blurred.

  20. Add secure tool support to Lumo for file creation, previews, and integrations

    Dear Proton Community and Development Team,

    I would like to suggest expanding Lumo with secure tool support so it can become more useful for practical daily work.

    At the moment, an AI assistant is most valuable when it can not only answer questions, but also help users create, organize, preview, and export work in a controlled and privacy-respecting way.

    Suggested tool improvements:

    1. File creation and export
      Lumo should be able to create files such as text documents, tables, simple presentations, ZIP archives, or structured project files and offer them as downloads.

    2. Secure preview features
      Lumo could provide previews for generated…
