  1. Desktop app and Lumo feedback connection to Proton Devs and Support

    First, Lumo pointed out that maybe having a desktop app, just like all the other apps that Proton offers, is beneficial for our needs, and maybe for others.

    Second, It would be nice if Lumo can send Dev Team feedback messages and get support for people. The latter especially helpful with non-technical people trying to explain a technical issue.

  2. Lumo Diary: Reflective Daily Journaling with Photos & Conversation History

    I'd like to propose a built-in Diary Mode for Lumo – a private, encrypted daily journal that grows naturally out of normal conversation.

    The Concept: Instead of filling out a journaling form, the user simply talks to Lumo during the day about what they did, thought, or experienced, and can attach photos. When the day ends (or the next day is opened), Lumo compiles the conversation and images into a structured diary entry.

    Key features:

    • Conversation-to-entry with timestamps: The day's chats become the raw material. Each new day gets a "page" in the diary. Each conversation segment is automatically marked…

  4. Lumo has gotten a lot faster since the 2.0 upgrade

    I use Lumo Max in thinking mode all the time, and I just noticed the lag has almost disappeared when it's responding. Just wanted to says thanks!

  6. How Do You Approach Law Coursework?

    https://writemycoursework.co.uk/law may sometimes prove to be tough since it requires a lot of legal research, case studies, law, and referencing. I would like to know which aspects of LLB coursework help UK prove to be difficult for other law students. Is it sourcing information, applying legal principles, IRAC, or something else?

  7. Title: Per-conversation memory control: "New Private Chat" option + memory containers

    Hi Proton Team,

    Memory shipped with Lumo v2.0, and it's a genuinely useful feature — but right now the only control is a global on/off toggle. I'd like to suggest finer-grained control, in two parts.

    Part 1. "New Private Chat"

    A conversation with no memory loaded in, and no memory saved out. Like a browser private window: fully functional, nothing retained afterwards. Your existing memory stays intact for all your other chats — this session simply doesn't participate.

    Visual indicators:

    In the sidebar: a small icon (lock, or similar) next to the conversation title — left side for LTR languages,…

  9. Preview Images in Project Knowledge Before Deleting – Show Thumbnails or Click-to-Open

    Currently, when viewing files in the "Project Knowledge" section, images are displayed only as generic icons with filenames (e.g., IMG_9630.png). There is no way to preview the actual image content before deciding to delete it. This creates a significant risk of accidentally deleting the wrong image, especially when managing multiple uploads with similar or non-descriptive filenames.

    I request a preview feature for images in the Project Knowledge panel with the following specifics:

    • Thumbnails: Display small thumbnail previews of the images instead of just generic icons so users can instantly identify the content.
    • Click-to-Open: Allow users to tap or click an…

  10. Anthropic Claude and Google Gemini Import

    Visionary user here switching from Anthropic Claude and Google Gemini to Proton Lumo Max I'd like to have an option as a user to import my data and memory as easy as possible. Today a manual import usually exceeds the context of the chat and even with multiple chat's it's not possible to get all data into Lumo. So please Proton give us an option to import our data.

  11. Hide events from shared calendar

    When looking at a calendar that is shared with you, you may want to hide some events and event chains.

    We share calendars across our family, some like to put "work" or "commute" in there, I would like to hide those event chains without hiding their entire calendar.

  12. Integrated Notebook with Offline/Online Toggle & Nested Folder Structure

    Description: While existing requests cover "Offline Chat Access" and "Project Folders," I need a dedicated Integrated Notebook feature to permanently capture, organize, and secure specific insights extracted from our conversations. Currently, valuable information gets lost in endless scrolling or requires exporting to external tools.

    I request a native Notebook within Lumo with the following capabilities:

    1. Seamless Capture from Chat
    • Highlight any message or paragraph in a chat and instantly "Save to Notebook."

    • Saved notes become standalone, editable entries but retain a link back to the original conversation for context.

    1. User-Controlled Privacy (Offline vs. Online Toggle)
    • Crucial Feature: Users must be…

  13. Lumo AI-Powered Card Organization for Proton Drive & Brain

    Enable Lumo AI to automatically organize, tag, and summarize saved cards in Proton Brain/Drive—zero-knowledge semantic search and connection discovery.

    BACKGROUND:
    This complements the "Proton Brain" feature request (UI focus). This one focuses on the intelligence layer that makes the system actually useful.

    CURRENT STATE:
    Users manually tag, categorize, and link notes. This is tedious and rarely done consistently. MyMind solves this with AI but sacrifices privacy.

    REQUESTED CAPABILITIES:
    1. Automatic Card Enrichment (Opt-In):
    - On save: Lumo generates summary (TL;DR, max 3 sentences)
    - Auto-tags extraction (3-7 relevant tags per card)
    - Entity recognition (people, places, topics mentioned)
    - Language…

  14. Cloud-Assisted Verification ("Draft Local, Verify Cloud")

    Here is my proposal which I think good to implement. (Note: I'm using LUMO itself to help me to produce a proposal based on my ideas)

    Problem: Small on-device models (7B–20B) are prone to hallucination on complex tasks — inventing facts, generating incorrect syntax, or producing logically inconsistent output. Pure local inference is risky for high-stakes work (configuration changes, security analysis, medical/legal information).

    Proposed Solution: A three-layer pipeline where local generation is verified by a cloud model — without exposing raw user data.

    Architecture — "Local Generation + Cloud Verification":

    Layer 1: Local Generation (Instant & Private)

  15. Filtering Thinking

    I posted the suggestion for thinking to be part of the output, but due to the 1 suggestion per topic, this is a follow up but second suggestion. However it's vital to understand that this IS assuming that the "thinking is output" suggestion is implemented.

    The idea is a bit wierd so bear with me.

    I keep seeing Lumo thinking, understanding what i asked it, and as it wants to start, i see

    "wait... maybe"

    or

    "what if"

    And similar stuff that simple are not ok because Lumo actually understood what i was saying and asking and then talked about…

  16. Thinking to be part of the output

    When thinking is on, i really wish that the thinking was included in Lumos output for one critical reason: Lumo can't recall whatever it concluded during thinking.

    And like this we waste a lot of time

  17. Personality fragments to filter out system prompts

    Custom Lumo is not working as Lumo's System prompts are still overwriting everything.

    My suggestion was initially to ask for the custom Lumo to not be affected by System Prompts like "be engaging" or "argue with user so user understand better" <- except lumo just arguest.... Or "when given a picture summarise what it says" or one of the worse: "if mistake found, stop and acknowledge" ... and lumo does exactly that... no matter what task, it just stops and keeps naratating about what it did and what it should have and not focusing on the tast. Let me not…

  18. Give fine tune selection over models

    GIVE US, FINAL USERS, FINE TUNE SELECTION OVER THE MODELS FOR EACH ASKING! And I mean the BEHIND models, the open source models behind LUMO. Why?? Because IT should be GREAT to test, over and over again, to messy around, to make (more) OUR the output! AND... it will cost you almost nothing to add this controls!

  19. Projects Marketplace

    I would like to be able to create Proton Projects and then sell the finished project to another user of Proton Lumo. A marketplace where Lumo users could see what projects are available for them to purchase or if free add to their Lumo as a custom project. For the Lumo Projects purchased hide the underlying code. When the purchased Lumo Project gets updated roll out to all of the buyers / users of marketplace proton projects.

  20. Make Lumo legal research privileged

    This is an additional business model leveraging Lumo and fixing a known severe privacy vulnerability.
    1. Establish a genuine Proton Law firm with actual bar approved lawyers/counselors, etc.
    2. Offer legal insurance subscription the provides some level of support from this actual staff of certified humans.
    3. Provide this access by leveraging Lumo as an incoming customer screening system to help customers get to the right lawyer.
