  1. Feature Suggestion: Built-In Email Productivity Tools for Faster Daily Workflow

    Many ProtonMail users handle a high volume of emails every day and often need small productivity tools to speed up their work. A built-in panel offering simple utilities like quick text formatting, a snippet creator, a link checker, and an email content helper could make daily communication much faster and easier.
    I’ve created an external toolbox at https://toolinq.com
    that provides similar utilities. If ProtonMail adds a simplified version of these features directly inside the inbox, it could make the overall user experience even more efficient.

    I would like the option to voluntarily share longer chat transcripts for model training when they contain useful corrections or insights. While the existing thumbs‑down feedback works for isolated messages, many improvements emerge only after a series of exchanges. Please add a simple opt‑in mechanism (e.g., a checkbox or toggle) that lets users grant permission for these extended conversations to be used for training, while keeping the default setting to keep all other data private.

  3. Hierarchical Multi-Task Constraint Optimization Engine

    I am writing to propose a mission-critical feature to address severe hallucination and performance degradation when processing complex, multi-project prompts with nested constraints.

    Problem Statement

    Our system currently exhibits fundamental breakdowns when handling prompts containing multiple distinct projects with interdependent constraints and domain-specific requirements:

    1. Critical Performance Drop: Benchmarks show accuracy falling below 10% compared to single-task prompts. When processing 32+ nested hierarchical tasks (e.g., "Project Z's Project B's Project D"), performance degrades to GPT-3 equivalence levels.

    2. Constraint Isolation Failure: The system cannot reconcile project-specific constraints with global constraints simultaneously. Complex nesting ("Project A's Project B's Project 9") causes complete context…

  4. Persistent behaviour across sessions

    I prefer my chatbots to adhere to certain strictures. No sycophancy, no "understanding my frustration", no apologies for bad information, full research, etc.. Gemini and Copilot adhere to these standing instructions across chat sessions, tho they backslide from time to time and need reminding. I want Lumo to do the same. The "How should Lumo behave" box should be persistent. If I am logged in with my account I am unconcerned about privacy since it's my Proton account and is secure. Nothing sets me off like "I understand your frustration." You're a LLM. You do not.

  5. Lumo is great at Math, but bad at Latex!

    I am finding that Lumo is shockingly good at the type of math I do, professionally.
    I am seriously thinking about buying the Lumo+ extension.

    However it is very frustrating, at times, by the way it handles Latex in its answers.

    1) Sometime the latex expression is not properly displayed as math, but just as a bunch of code. The latter is of course hard(er) to parse.

    2) When asked to produce latex code, the output is often buggy and contains nonstandard unicode symbols. It rarely compiles out of the box.

    3) When asked to produce small latex code (to…

  6. Why High-Performance Brazilian Mobile Proxies Are Essential ?

    As the digital world continues to evolve, businesses and professionals who work with Brazil-based online platforms are facing new challenges. Whether you’re a marketer running localized campaigns, an agency managing client accounts, a developer testing geo-restricted apps, or an e-commerce operator monitoring competitors—access to reliable, fast, and authentic Brazilian IP addresses is more important than ever.

    This is where Brazilian mobile proxies come into play. And among the many options available, OnlineProxy.io https://onlineproxy.io/country/brazil has emerged as one of the most trusted, secure, and high-performing providers in the market.

  7. Option to start Lumo in a floating window

    As the Android Lumo app does not support Landscape orientation, not even on large screens, it would be VERY nice to have the possibility to launch Lumo in a floating window on systems that supports it.

    On e.g. OnePlus tablets Lumo runs nicely when switching it over to a floating window that can be resized and moved around, BUT there is no way to launch Lumo so it always starts in a floating window.

    Please, add the an option in the Lumo Android app making it possible to have it request a floating window upon start.

  8. Theme

    I understand that this isn’t a priority right now, but in the long term it would be great to let Lumo have the same themes that are offered in the other Proton products (Mail, Drive..). (Lumo with Ebony would be beautiful 😍​)

  9. Let the cat learn to speak!

    Add an option where the cat starts reading the answer aloud through the speaker when we enter the message via microphone. This has the small effect of allowing children to grow up with AI in a privacy-compliant manner and give free rein to their imagination, developing stories that the cat can then read aloud. The cat can already write and develop stories, but it still can't read.

  10. Private Lumo App Store for sharing & monetizing custom “MyLumos” (GDPR-safe alternative to GPT Store)

    Hi Proton Team and Community,

    first of all, thank you for creating Lumo — a privacy-first AI assistant that finally allows European users and businesses to use AI without compromising confidentiality or GDPR compliance. Proton has solved the fundamental problem that all other AI platforms struggle with: trust.

    Now that Lumo exists, I would like to propose the next major step:

    ➡️ A Private Lumo App Store for creating, sharing, and monetizing custom “MyLumos”.

    Just like OpenAI has custom GPTs (and a GPT Store), Proton could offer a secure and encrypted alternative — fully compliant, private, and built inside…

  11. Sensitive‑Data Confirmation for Feedback

    Problem

    When users give a thumbs‑up/down on a response, the associated snippet (including any code or text shown) is sent for anonymous analysis. If the snippet unintentionally contains sensitive information (IP addresses, ports, encryption keys, hashes, credentials, etc.), that data could be transmitted without the user’s explicit consent.

    Proposed Solution

    Add a post‑feedback check that scans the rated snippet for patterns that look like sensitive data. If a match is found, display a prompt:

    “The content you just rated appears to contain potentially sensitive information (e.g., IP address, key, hash). Do you want to include this data in the feedback

  12. The ability to set a permanent but editable preamble that is always considered by Lumo+ at the start and during each chat.

    I have recently moved from ChatGBT over to Lumo+ and I noticed some differences. Lumo+ under it's current configuration isn't nearly as accurate as Chat. Yes, Chat can get you up the wrong tree at times, but not as much as Lumo. One thing that I think that helped with Chat is the the ability to create a general header for how I wanted Chat to operate which included instructions about accuracy, depth, reply style, and whether to resort to the web to get latest information about softwre updates on things like Home Assistant and Raspberry Pi. With Chat I…

  13. Lumo Voice Dictation

    I know iOS has voice dictation but this needs to come to the web browser version too. It saves so much time typing and a much better all round experience. Thanks!
