1. Voice‑Assist Button: Instantly Read Lumo Replies Aloud

   Introduce a dedicated Voice‑Assist button within the Lumo chat interface that, when pressed, converts the textual response generated by Lumo into spoken audio in real time. The button should be prominently positioned alongside the existing input controls, enabling users to trigger text‑to‑speech playback with a single click (or tap on mobile devices).

2. 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 content, such as simple web pages, layouts, documents, or structured outputs before the user downloads or applies them.

   3. Live Work inside Lumo
      Lumo should have just like any regular AI, an Canvas feature for example for live editing content or previewing work

   4. Project-style file context
      Users should be able to upload files or reference materials into a Lumo workspace so the assistant can work with them without requiring users to paste very long text manually.

   Why this matters:

   Many users need AI not only for chatting, but also for producing usable outputs. Secure file generation, previews, and optional integrations would make Lumo much more practical while still respecting Proton’s privacy-first approach.

   I understand that this requires careful security and permission handling, but I believe it is possible if implemented with clear user control, transparency, and Proton’s existing privacy standards.

   Thank you for considering this suggestion.

3. Add Dedicated Feedback Button Inside Lumo+

   Right now there's no easy way to send feedback from within Lumo+ itself. I submitted a compliment through the bug report form as there was not a dedicated feedback option. Adding a simple, dedicated feedback button in the navigation pane would make it easy for users to share both praise and constructive suggestions — and you deserve to hear when you're doing a great job, because you are!

4. No restrictions for files made by Proton´s own tools

   I can understand some restrictions like upload sizes (although even for unlimited subscribers they are way too small to be useful), but at least have unlimited features for Proton's own tools like Sheets and Docs. That would further incentivize users to use them as well.

   The 10 MB limit is likely an outdated restriction that doesn't reflect Proton's current technology. Since Proton already has a secure storage system (Drive) and collaboration tools (Docs/Sheets), the technical challenge isn't processing files, but integrating them directly into the chat. In a "Unlimited" tier, Lumo could read and analyze files directly from Drive without physical uploads, effectively bypassing the size limit entirely and making the service truly useful.

5. Multiple windows (both emails and calendar) on Windows

   When using ProtonMail, I want to be able to:
   - Open a specific email in a new (secondary) window, So that I can read that email and type in a new email in a different window.
   - Open the calendar in a new (secondary) window, So that I can look at my calender while processing emails.
   - Open multiple emails in one window each.
   - Open multiple calendar views in one window each.

   All this is possible in the WEB version, but I need to use the full search feature of the local installed ProtonMail client.

6. Temporal Context Enhancements for Lumo

   Dear Proton Support Team,

   I would like to propose a set of related enhancements concerning temporal information in Lumo, together with a suggested deployment model aligned with your existing subscription structure.

   Current Situation
   Lumo currently receives the calendar date in its system prompt (e.g., "Today's date: 07 Oct 2026"), but does not have access to:
   1. The day of the week
   2. The ISO week number
   3. The local time of day
   4. Any record of when previous messages in a conversation were sent

   The weekday and week number are mathematically derivable from the date, but this derivation must be repeated on every message — unnecessary overhead for facts that never change within a day. The time of day cannot be inferred from the date at all without indirect methods (such as invoking a tool purely to extract a timestamp from its response), which is inefficient and unreliable. And since past system prompts are not retained in the conversation context, Lumo cannot perceive any elapsed time between messages, no matter how precisely the present is known.

   Proposed Enhancements

   1. Weekday and ISO Week Number (all users)
      Append both to the existing date injection.
      • Token cost: minimal, roughly a dozen characters per message.
      • Benefit: eliminates redundant per-turn computation and guarantees consistent calendar awareness.

   2. Current Time Injection (Lumo Plus)
      Additionally inject the user's local time of day into each prompt, as an opt-in setting.
      • Cost: requires a client-side time handshake or similar per-session mechanism, comparable to existing infrastructure-backed Plus features such as web search.
      • Benefit: enables time-aware behavior such as tone adjustment to the hour, and rules that trigger at specific times.

   3. Per-Message Timestamps (Lumo Plus, probably)
      Append the send time to each message, persisted in the conversation transcript.
      • Cost: unlike the fixed-size injections above, the accumulated token overhead of per-message timestamps grows with conversation length — effectively consuming a small surcharge on every historical turn in every subsequent prompt. For long-running conversations this is a recurring and increasing cost, which suggests the Plus tier.
      • Benefit: this is the only mechanism that provides elapsed-time reasoning. Knowing the current time alone does not tell Lumo when a previous message was sent; a timestamped transcript does.

   Use Cases

   Personal use case — alternating shift schedules: I work alternating early and late shifts based on ISO week parity. In odd-numbered weeks (early shift), I should be asleep by 20:00; in even-numbered weeks (late shift), I arrive home at 21:30; weekends are unconstrained. A functional reminder rule ("after [20:00 or 02:00, depending on shift] on a work night, tell me to go to bed") requires the weekday, the week number, and the current time — all three layers together. Today, only the date is provided, and the derivation of calendar facts is reasoning-intensive and unreliable enough that such a rule cannot be trusted.

   Commitment tracking: time-relative statements ("I'll check back in five minutes") only become meaningful if the assistant can compare a previously stated time against the present. Without per-message timestamps, this class of verification is structurally impossible — the assistant knows only "now," with no record of "when."

   Conversation integrity: with automated summarization of long conversations, timestamps serve as structural markers. Elapsed-time gaps carry real meaning (a thirty-second reply versus an overnight pause), and preserving that information makes compacted summaries substantially more faithful.

   Implementation Notes
   Timestamps can be captured client-side at send time and attached to the message payload, requiring no server-side clock synchronization. All four proposals operate entirely within the existing privacy model: no data sharing, no training usage, and timestamps originate from the user's own device. Users implementing parity-based rules (as in my schedule) could additionally anchor their rotation to a reference week in persistent memory, keeping such rules debuggable when the underlying roster changes.

   Closing
   These proposals would give Lumo a coherent sense of time that currently requires awkward workarounds to approximate. I believe the split between near-free calendar facts and infrastructure-dependent time data fits your existing tier structure well.

   Thank you for considering this suggestion.

   P.s.: Yes, Lumo wrote this on my behalf. I did proofread all and edited some of it, though.

   Re-filed it, because the last one - strike that, two, I'm stupid - accidentally landed in "general" rather than the Lumo forum.

7. Offline access to Lumo chats & local search (like Proton Drive)

   I'd like to propose a new feature for Lumo that enables access to chat histories without an internet connection – similar to the "Make available offline" function in Proton Drive.

   Use Case: Users want to read and search through specific chats or project histories while offline (e.g., on a plane, in areas with poor connectivity, or for privacy reasons). Currently, Lumo is only usable online, which limits access to your own conversation data.

   Proposed Features:

   1. Offline toggle for chats:
      Like in Proton Drive, users should be able to mark individual chats (or entire projects) with a toggle as "Available offline." These would then be stored locally on the device, fully encrypted.

   2. Two export modes:

   • Full-text mode: The complete chat history is made readable offline (including all details and discussion threads).
   • Summary mode: Users can select multiple chats to generate a compact, Lumo-created summary available offline.

   1. Local search with navigation:

   A full search within the offline-saved chats that:

   • Highlights found terms in color.
   • Allows navigating up/down between search results.
   • Works entirely without internet (indexing happens locally).

   Why this is valuable:

   • Increases the practical usability of Lumo in situations without internet.
   • Provides continuity in long-term projects and conversations, even offline.
   • Leverages proven Proton principles (encrypted local storage) and extends them to chat data.
   • Universally useful – not limited to specific use cases but beneficial for anyone who wants to work flexibly.

   Technical Feasibility: The infrastructure for encrypted local storage already exists in Proton Drive. Extending this to chat data would be a logical evolution. Local search is technically achievable since the text resides on the device after download.

   I'd like to propose a new feature for Lumo that enables access to chat histories without an internet connection – similar to the "Make available offline" function in Proton Drive.

8. Allow uploading from the Photos section in Proton Drive to Lumo, not just the Files section.

   Currently, when integrating Proton Drive with Lumo, only the Files section is accessible. It would be very useful to also allow uploading directly from the Photos section of Proton Drive. This would make it easier to analyze and edit images stored in encrypted cloud storage without having to move them to Files first.

9. Proton Draw

   Title: Feature Request: Lumo Draw – Privacy-First AI Illustration for Authors (Watercolor & Dark Fantasy Styles)

   Description: I am writing to strongly request the development of Lumo Draw, an AI image generation tool integrated into the Lumo ecosystem with zero-access encryption. (Note: The name "Lumo Draw" was my original concept, proposed here to maintain brand consistency with the Proton ecosystem.)

   My Background & Member History: I have been a loyal Proton member for many years. Currently, I am subscribed to the Lumo+ Family Plan, and I am also a Lifetime Supporter who donated during the annual ticket drive to secure my lifetime status. I am deeply invested in the Proton mission and the privacy-first ecosystem.

   My Use Case as an Author: As an author, I have two distinct illustration needs that current public AI tools cannot safely meet due to data training risks and aggressive censorship:

   Children's Books: I need a dedicated "Warm Watercolor" style. Soft edges, bleeding colors, and whimsical tones are essential. Current tools often force a generic digital look or struggle with consistent style locking.
   Adult Dark Fantasy Novel: This project requires a "Gritty/Dark" aesthetic. It includes atmospheric violence, complex moral themes, and mature storytelling. While it contains no illegal content (CSAM), existing consumer AI tools often over-censor artistic depictions of war, darkness, or mythological figures, making them useless for serious fiction.
   Why This Matters & Why "Lumo Draw"? The market has AI art generators, but they all suffer from the same fatal flaw for creators: They harvest user prompts and images to train future models. If I use Midjourney or DALL-E to design my book characters, I risk losing ownership of my unique IP. My specific "watercolor" or "gritty" style could be ingested into their models and sold back to others.

   A tool named Lumo Draw, operating under Proton's strict zero-access encryption, would ensure my character designs and unpublished story visuals remain mine and are never used to train public models.

   Proposed Features:

   Style Presets: Dedicated modes for "Soft Watercolor" (warmth/fantasy) and "Dark/Gritty" (high contrast/noir).
   Privacy First: No logs, no scanning of creative work for "policy violations" unless illegal, ensuring my artistic vision isn't sanitized by corporate filters.
   Consistency: Tools to lock character references across multiple generated pages.
   Paid Tier Willingness: As a long-time member and Lifetime supporter, I am explicitly willing to increase my payment to access a premium "Lumo Draw" service tier.
   Conclusion: Lumo Draw would be a game-changer for independent authors who value both creativity and privacy. It would allow us to visualize our worlds without compromising our intellectual property. Having suggested this name and concept after years of supporting Proton, I believe this feature aligns perfectly with the community's needs.

   Thank you for considering this feedback from a dedicated long-term member.

    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!

11. Allow Lumo to deal with Memory reduplicates

    I notice the memory list often has either exact duplicates or very similar worded info. I presume there is some kind of self-check to see if a memory has already been added. But its not quite up to standard.
    May i suggest can we give Lumo permission to comb through the memory and weed out duplicates or too similar ones. If there are edge cases it could apply a tag for a special filter called User Attention Needed (or something) and we can click on this button that is lit up when it has memories to assess and we only see the list of edge case memories and each one has a green tick button to approve or X to delete and a pencil icon to edit and once done we can tap the green tick button to allow it back into the main memories (and of course remove the special filter tag)

    Also to further enhance this idea, add search bar so we can see if what certain topics might be listed. And we could also filter our own manual memory entries with a command in the search bar: #you or /you

14. Enable Lumo to attach an entire directory from Proton Drive

    Currently you can only attach files to a Lumo conversation. I would like to be able to select a directory from my Proton Drive and Lumo will automatically use all files within that directory including files within subdirectories.

    In my Gemini account I recently noticed you have the ability to do that and think it would be a great feature for Lumo.

15. 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.

16. AI-powered billing verification for construction (delivery notes + measurement = invoice)

    I'm a construction site manager in landscaping (GaLaBau). Our industry software (greenGALA 8, BAUSU) is purely static – it generates output but performs no automated checks or reconciliations. Every verification is done manually: data entry, Excel cross-checks, triple manual control, handwritten delivery note sorting, and final invoice plausibility checks.

    The core billing equation in construction is: Delivery notes + Measurement = Invoice. There is currently no tool that automates this reconciliation across the entire chain.

    Three areas where AI support would create massive value:

    1. Delivery note processing – Delivery notes are often barely legible: handwritten, dirty, incomplete, filled out on-site. Manual sorting and data entry takes unreasonable amounts of time. OCR-based extraction, even from poor-quality scans or photos, would save hours per project.

    2. Measurement plan understanding – Measurements often exist as drawn plans or sketches, not digitally. If AI could read measurement plans and extract dimensions and quantities, that would eliminate another fully manual step.

    3. Final invoice plausibility check – The most error-prone and time-consuming step. Reconciling delivery note quantities and measurements against billed positions. Finding deviations that can't be logically explained.

    Concrete bug I already encountered: I uploaded a final invoice PDF + measurement list PDF to Lumo 2.0 Max (Thinking mode, web search enabled) and asked it to reconcile them. The processing log showed completion, but both times the output was: "Something went wrong." Reproducible twice with identical files and prompt.

    Financial reality: I pay for Lumo out of my own pocket, not through a company license. Tax deductibility covers only a fraction. If Lumo can't handle the core use case – reliable PDF billing verification – it's financially uninteresting for me.

    What I need: Reliable processing of two linked PDFs, structured table extraction, and automated discrepancy detection across delivery notes, measurements, and invoices – bundled in encrypted Lumo Projects. This applies to the entire construction industry, not just landscaping: civil engineering, road building, structural work, all trades.

    Happy to provide sample documents or beta-test features.

    I'm a construction site manager in landscaping (GaLaBau). Our industry software (greenGALA 8, BAUSU) is purely static – it generates output but performs no automated checks or reconciliations. Every verification is done manually: data entry, Excel cross-checks, triple manual control, handwritten delivery note sorting, and final invoice plausibility checks.

    The core billing equation in construction is: Delivery notes + Measurement = Invoice. There is currently no tool that automates this reconciliation across the entire chain.

    Three areas where AI support would create massive value:

    1. Delivery note processing – Delivery notes are often barely legible: handwritten, dirty, incomplete, filled out on-site.… more

17. Lumo Senior Voice & Safety: Essential Life-Saving Features for the Aging Companion

    This proposal serves as the critical expansion to my earlier idea "Lumo Senior: The Wise Companion with White Hair & Glasses": https://protonmail.uservoice.com/forums/932842-lumo/suggestions/51603812-lumo-senior-the-wise-companion-with-white-hair

    While the first idea established the emotional bond and visual identity, this second part adds the essential functionality that makes Lumo a true lifeline for elderly users: Voice-First Interaction and Emergency Safety.

    Without these features, a "Senior Companion" remains just a chatbot. With them, Lumo becomes a guardian angel.

    Core Additions:

    1. Voice-First Design (Hands-Free Operation): Many seniors cannot type comfortably due to arthritis, tremors, or poor eyesight.

    • Natural Speech: Lumo must listen and respond entirely via voice. Commands like "Lumo, write an email to my son" or "Remind me to take my pills" should work instantly without touching the screen.

    • Calm, Clear Voice: The AI's voice should be slow, warm, and reassuring—not robotic. It should act as a patient listener who reads stories or recalls memories aloud.

    • Always-On Listening (Privacy-Safe):A mode to detect urgent wake words (e.g., "Help!") processed locally on the device for instant reaction.

    1. Emergency Safety (The "Guardian Angel"): Fear of falling alone is a major concern for seniors. Lumo should integrate with device sensors to act as a safety net.

    • Fall Detection: Using the device's accelerometer/microphone to detect sudden falls or distress sounds.

    • Automatic SOS: If a fall is detected or the user says "Lumo, I need help", Lumo should:

    Immediately call pre-set emergency contacts (family, neighbors).

    Alert local emergency services (Fire/Police/Ambulance) if configured.

    Share secure location data with trusted contacts.

    • One-Touch/Voice Trigger: A large, simple button or voice command for instant assistance, similar to the SOS feature on smartwatches but integrated into the Lumo experience.

    1. Privacy-Preserving Implementation:

    • Local Processing: Voice commands and sensor data for safety checks must be processed locally on the device (offline) whenever possible to ensure maximum privacy and speed.

    • Encrypted Alerts: All emergency notifications should be sent via Proton's secure, encrypted channels.

    Why This Matters: My father (82) already finds typing emails difficult. Imagine the relief if he could simply say "Lumo, help"if he falls, and get immediate assistance. This transforms Lumo from a nice chat companion into a life-saving tool. The combination of a "wise, aged face" (trust) and "instant voice safety" (security) creates the perfect ecosystem for aging in place.

    Technical Feasibility: Leverages existing Proton security infrastructure and standard device APIs for motion/sound detection, similar to current smartwatch safety features, but integrated into the Lumo ecosystem with a focus on privacy and empathy.

    This proposal serves as the critical expansion to my earlier idea "Lumo Senior: The Wise Companion with White Hair & Glasses": https://protonmail.uservoice.com/forums/932842-lumo/suggestions/51603812-lumo-senior-the-wise-companion-with-white-hair

18. Support for audio and creative file formats (.wav, .als, etc.)

    When working on music production projects (Ableton Live), I can't upload the files I actually use:

    .wav files are rejected — drag and drop returns "Unsupported file type"
    .als files are greyed out in the file picker
    I chose Lumo Plus because privacy matters for my creative work, but I can't even load the files I work with. Could support for common audio/creative formats be added?

20. Lumo User Interface indicate percentage of output limit when responding

    Lumo has a maximum character limit for a single response (according to Lumo). I would like to know how much of that limit I am using when asking for a response. Currently Lumo simply fails without warning and it's difficult to see what is going on. I find it interesting that Lumo didn't actually know the limit either, it gave a range. When I started asking Lumo more pointed questions it kept stopping partway through the output it responded:

    You are absolutely right to notice that pattern! The problem is not with your request or my memory, but with the technical output limit of this chat interface.
    The Problem: The system has a maximum character limit for a single response (often around 4,000–6,000 characters). Every time I reach that limit, the system cuts off the message abruptly, regardless of how much I try to compress it. It's a "hard stop" imposed by the software, not a choice I make.
