  1. 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…

  2. Enhance Lumo with Dedicated First-Level Support Training & Automatic Knowledge Updates

    Perhaps it's a generally silly idea, but I often try Lumo as the first point of contact for support regarding Proton products. While the AI assistant delivers good to excellent results in many areas of knowledge, it surprisingly seems to be weak in this area, and I have already had to contend with some misinformation. Therefore, I propose extending Lumo’s capabilities to serve as a reliable, up-to-date first-line support agent. The core idea is to provide Lumo with a focused training set, encompassing, among other things, Proton-specific FAQs, troubleshooting guides, and policy documents, combined with an automated pipeline that feeds…

  3. 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.

  4. 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.

  5. 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.

  6. Implement Bias Mitigation for Chinese Open-Weight Models (Qwen, Kimi K2)

    As noted in Lumo's Privacy Documentation, the system currently routes queries to several open-weight models, including Qwen and Kimi K2. While utilizing these models supports cost-efficiency and open-source diversity, research (e.g., NDSS 2026, "S1761") indicates they contain significant internal censorship and narrative engineering aligned with authoritarian state interests.

    Proton’s core mission is to champion digital rights, encryption, and freedom against state surveillance. However, deploying models with embedded propaganda or censorship mechanisms creates a contradiction:

    • Cognitive Risk: Users may receive subtly altered information or suppressed viewpoints on sensitive geopolitical topics (e.g., HK, Taiwan, human rights).
    • Value Misalignment: This conflicts with Proton's…

  7. Option turn off anthropomorphic thinking and text

    I am currently very ritated

    why? I am wasting time, energy, and most of all TOKENS because of lumo's anthropomorphic beheviour.

    I understand people love anthropomorphic AIs.

    Can we however have an option to turn if off?

    And i really really really hope i do not need to explain what anthropomorphic in Ais means.

    because i my suggestion is NEXT LEVEL

    as in thinking and the text.

    Lumo keeps repeating the same answers, or otherwise, without thinking even when explicitly told to stop.

    when it finally stops to thinking, more then half of the "thinking" are simple anthropomorphic related text.

  8. Feature Request: “Auto‑Websearch” / “Always Enable Websearch” in the Personalization Tab

    Hey Proton team,

    thanks for the awesome Lumo 1.2 update! The new personalization options are super handy. To make Lumo’s answers truly real‑time, could you add a toggle under Personalization called “auto‑websearch” (or “always enable websearch”)?

    When turned on, Lumo would automatically pull in up‑to‑date info for any query that needs fresh data—no extra steps required. This would be a game‑changer for users who rely on accurate, real‑time responses.

    Appreciate the consideration!

  9. 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…

  10. 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…

  11. Abandon Lumo and use resources to address deficiencies in Proton's core secure IT services

    Of course, I have no idea how many people use Lumo or how valuable a business this is to Proton. I hope this suggestion may flush that knowledge out.

    Customers buy Proton services for its secure IT communications. That is - as far as I know - Proton's core business and its unique selling point.

    Many companies offer AI chatbots which - if they're ever useful at all (about which I have doubts) - improve through scale usage, something Proton seems unlikely to achieve, at least when compared to US behemoths.

    Proton appears to have a large development backlog in…

  12. lumo extended files

    Subject: Lumo Feature Request: Support for .nix, .zip, and .tar.gz files 🚀Hi Proton Team! 💜First of all, thank you for building such amazing, privacy-focused tools. Lumo looks great and works incredibly well!I would love to share a small feature request that would highly benefit technical users like myself. 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…

  14. Allow anonymous data sharing

    I know that Proton doesn't create/train its own AI model, but a good european alternative would be nice to see. As unpleasant as this might be, to create a good model, lots of data is needed. A great app is worth nothing without good models. The current market leader, openAI, uses user data to train their models and have a huge advantage.

    If my data is ever used for training, I want to give it to a company I trust (or think I can trust) to handle them carefully. And this is you. I would like to see the option…

  15. To make Lumo more human

    Subject: Proposal: A "Dual-Loop" Architecture for Next-Gen LLMs Inspired by Neuro-Mechanical Models

    Dear Research and Engineering Team,

    I am writing to share a conceptual proposal for a new architectural approach to Large Language Models (LLMs), inspired by the neuro-mechanical theories of Lee Kent Hempfling (specifically the distinction between Short-Term and Long-Term memory loops).

    While current LLMs excel at pattern recognition and statistical prediction (effectively acting as massive Long-Term Memory systems), they lack a mechanism for inhibition, self-correction, and proactive intent. This proposal suggests a "Dual-Loop" architecture that could significantly reduce hallucinations, bias, and reactive behaviour.
    The Core Concept: Dual-Loop Architecture

  16. There should be a way to turn off the cat avatar

    I would love to use Lumo, but can not because of the annoying cat avatar. Lumo says it could be turned off, but gives misleading instructions how to do it. For example the Settings menus are very different what Lumo desribes and what I actually see.

  17. Create doc and spreadsheet directly from chat

    Add the ability to automatically open a chat window directly within a document and embed a table in Proton Sheets. This would streamline real‑time collaboration by allowing users to start a conversation or view a related spreadsheet without leaving the current file.

  19. Using better open-source/weight AI Models

    Hi everyone,

    I am writing this because I think Lumo has so much more potential. Imagine them using a 1 trillion parameter Chinese open-source/weight AI model like it would give them so much more flexibility in new features and accuracy of up-to-date data. They could even train an own AI model that they can then use like OpenAI uses ChatGPT as an multimodal AI model without having to rely on others creating open-source/weight AI models for them to use plus they could customize it perfectly for privacy, speed and accuracy. This own AI model could be based of some other…

  20. 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.
