  1. Any integration of A\nti I\ntellect tech into Proton products must be 100% OPT IN and switch enabled on a PER USE basis.

    Given the countless ethical concerns, hallucinatory output failings, hugely excessive environment threatening energy costs and sick greed motives of its Bloated Bloodsucking Billionaire tech bro parasite promoters, A-nti I-ntellect technologies are proving toxic to both society and our planet on every level, starting with the fact that all of the Large Language Models were trained on the A-bducted I-ntellect of human beings that was stolen without notice or permission from its copyright holders, authors and creators globally. It is critical that internet users who understand the need for Ethical Tech (exemplified by the privacy protections of Proton products and services,…

  2. Letting programmers use Lumo in a code editor

    As a developer, I added extensions to my code editor. Some companies offer extensions to use their AI models directly in a code editor, like "Claude" extension in VS Code. Being able to work with the AI within the code editor is a huge time saver.

    It would make Lumo an even more useful tool for programmers and help improve their workflow.

    Could you make the same with Lumo?

  3. 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…

  4. short key for new line / marker blok to enter code

    When I am using lumo to help with coding, I need an option to make a clean new line, to activate the marker box or to enter code the right way. The enter key leads to submitting my chat, and shift + enter or alt + shift + enter won't work, as the chat interface does not interpret them as 'new lines'. This makes it impossible to enter code. The only work around that works is entering the whole marker box (including markers) in notepad, copy, paste.

  5. Import chat history from other LLM

    Please allow us to import chat history from other big commercial cloud hosted LLMs to ease transition and not lose all the information prior LLMs gleaned from us, what we are doing, what is important to us, etc.

  7. Add Kimi K2 thinking

    huggingface.co moonshotai/Kimi-K2-Thinking

    Hi! would make sense to have it as a main OSS model as it is the SoA (the most "intelligent" one that is also open source!)

  8. Multiple Personalities - more control & community templates

    Currently, under the 'Personalization' you can create ONE personality per user. Depending on my task at hand I need more control over the expected output. As currently there is not really a good way to configure the expected outcome. (e.g. how 'creative' the model can be or how strict it needs to adhere to the input).

    This feature would also really benefit from (community) templates which must be editable for better control.

  10. Improved visibility of the Internet search icon in Lumo

    I find the current icon for the integrated Internet search in Lumo difficult to distinguish, especially with dark themes or low screen brightness. I suggest introducing a clearer, higher-contrast icon that automatically adapts to the selected theme (light/dark).

    Possible implementation:
    A minimalist magnifying glass icon with a subtle frame that is highlighted in color when search is activated.

    Optional: A short tooltip display (“Start/stop search”) when pressed and held to support new users.

    A clear icon makes it easier to find and activate the search function, which increases the overall usability of Lumo.

  12. Provide a Way to Hide Lumo

    I really hate this AI fad, because it is bad for the environment and will probably result in people losing their jobs and getting replaced by machines that can't actually do them, and is a privacy nightmare, and the models were trained on stolen data, so I would like to be able to stick my head in the sand and ignore it for as long as possible. Can you create a setting that would allow us to hide any mention of Lumo anywhere? I have been using uBlock Origin for this, but I occasionally have to go back in and…

  13. Improving response quality and reducing bias

    As it is, Lumo doesn't work very well.

    It hallucinates facts more often than other modern models that also don't access the web. When asked about privacy-related questions, it almost always promotes Proton's services (including ones that don't exist such as "Proton Chat"). I understand that there is an incentive to promote the company's own services, but most people interested in a privacy-respecting LLM, and especially those willing to pay, don't want it to act as a shill for Proton.

  15. Accept all text files, independently of their extension name.

    Lumo is able to read and understand many text-based files (LaTeX, json, python, etc...). However, only .txt files can be uploaded (files without .txt extension name are refused). It would be nice to accept a larger set of file, as Lumo is able to read them once renamed with a .txt. Lumo shall be able to recognize them correctly, without enforcing in the chat was format is intended to be the submitted file.

  17. Let Lumo reference past chats & have memory

    Hello Proton Team,
    I would like to suggest adding a new feature to Lumo that allows it to collect personal information and interact with users in a manner similar to ChatGPT, but with a strong focus on privacy. The idea is to enable Lumo to understand and assist users by learning from their information, preferences, and interactions — all while ensuring that this data is fully private and protected via end-to-end encryption.
    This would combine the convenience and intelligence of an AI assistant with Proton’s commitment to user privacy and security. It could open up new possibilities for personal productivity,…

  18. Personal Assistants / Preconfigured Prompts in Lumo

    I’d like Lumo to support personal assistants or preconfigured prompts, similar to what Kagi Assistant and other AI tools already offer.

    This would make it easier to switch between different roles (e.g., researcher, writer, teacher, developer) without having to retype or remember long instructions each time. It would also give users more control and flexibility to adapt Lumo to their own workflows.

  19. File types and size / unsupported file types

    The current file types to upload f.e. images don’t work well and constantly I’ll get the message of “unsupported file type” in the pop-up window and that’s a false flag. They are all files types that Lumo support. I can open those files without any problems within Proton Drive or iCloud. Same issue occurs on Windows desktop, iPhone and iPad. Drag and drop makes no difference.

    The file size is also an issue, limited to 10MB and I have a subscription. An average photo is already more than that. Files stored in Proton Drive can be uploaded with a maximum…

  20. Feature Request: Exclusive Access to Larger LLMs for Lumo Plus Subscribers

    I would like to propose a feature specifically for paying Lumo Plus subscribers: the ability to enable Lumo to use larger LLMs (such as GPT-5, GPT-5 Thinking, Gemini 2.5 Pro, Grok 4, Claude Sonnet 4.5, etc.) for processing queries. The core idea is for Lumo to act as a privacy barrier—protecting user data—while still taking advantage of the advanced capabilities of top-tier models for those who subscribe.
    This enhanced feature should be strictly limited to users who actively pay for Lumo Plus. Free users would continue using the current models and would not have access to this option.
    Lumo Plus…
