  2. Add "Green" and "Research" Search Modes

    When searching in Lumo, users should be allowed to toggle on different types of searches, such as:
    1. Green - a search that uses less environmental energy to generate an answer
    2. Research - a search that goes deeper and uses reputable sources (similar to the Research function already present in Mistral AI's Le Chat)

  3. Lumo payment separate from my other products

    Currently, to sign up for Lumo+, you must add it to your current subscription, with the same time period, so if you have a 1-year subscription, you have to pay for 1 year of Lumo, if you have a 2-year subscription, you have to pay for 2 years of Lumo up front.

    The other option is to lose all the discounts on your main Proton account in order to activate Lumo+ for the new term.

    For example, if you have a 2-year Duo subscription (€11.99 per month) and you only want 1 month of Lumo for both users, you have…

  4. 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…

  6. Combine the lumo plan with mail and drive plan.

    Right now, I am paying for proton family, but the subscription does not carry over to Lumo. It wants me to pay for Lumo separately. Why doesn't proton combine them so that one subscription covers everything?

  7. Code blocks with syntax highlighting

    I think Lumo could benefit from code blocks (similar to what Claude has) that have syntax highlighting. Lumo already supports some Markdown syntax features, so it would make sense to add code blocks that are made up of the triple backticks with an optional language next to the starting backticks.

    I currently find it very hard to add code to Lumo when asking for information, debugging, or code edits.

  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!

  10. Dedicated app for Windows

    Create a web wrapper app like proton mail, but for lumo. Instead of having to load lumo in a browser as a tab. Currently this creates issues.

    1: A browser with many tabs will slow lumo down.

    2: Lumo's save ability is tied to the browser's startup behavior. If the browser is set to restore the previous session, then lumo will restore all conversations that are not in ghost mode. If the browser is not set this way, then certain new conversations are not restored when opening the browser. Having ghost mode disabled doesn't make any difference.

    Lumo could have…

  11. Proper Lumo mobile apps

    Lumo needs a proper app. Every other Proton app is designed to integrate into their respective systems, but Proton Lumo is just a web app, and it works just as well as any web app, which means not as well as it should. Lumo needs more love in this department, a proper mobile app.

  12. I would like to see Lumo become as good as ChatGPT is today.

    It’s hard to avoid using LLMs now - they work, and they help a great deal in a very demanding world. But something as good as ChatGPT is also a direct link between a corporation and my brain (unfortunately, it’s one-way only). Over time, they’ll have enough information about me - my work, my character, my hobbies, my thoughts… if they don’t already. That gives them a computer-brain interface, one that can be used to program my mind (if you’re into neuroscience and brain chemistry, you’ll know what I’m talking about). After all, people are programmed by their environment-and more…

  13. Let us click on our history to see all of our chats!

    I am currently using the android app (APK) and noticed that when I don't have everything in a project folder, it's hard to scroll down through my history. I'd like to be able to click the history for a tab and scroll through there to look for old chats. I do use search but sometimes what key words I look for overlap. I can scroll just fine on the desktop version. Wish I could do a mock image of what I mean to post here but I don't see a way to upload images here.

  14. Option to change avatar

    I wanted to suggest adding an option to customise or hide the default cat avatar. I'm not much of a cat person, so having the ability to change or turn it off entirely would be a great improvement.

  15. Creation of Lumo Browser Extension

    As a leading privacy AI, it's important that the chatbot can interact with our daily lives safely and privately. The addition of a browser extension for Lumo to interact with your screen would greatly benefit the greater Proton community.

  17. 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.

  18. 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. 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…

  20. Wider response area (smaller margins)

    On a tablet or portrait monitor, the response should take up the full width - currently there is a lot of wasted space on each side, with the response in a narrow center block.

    On larger screens, I still find it too cramped - especially with rich results such as tables. Tables are often very compressed and hard to read.
