  1. Great Potential the ability to use both Scribe & Lumo together, dream come true!

    I started with this in Scribe then copy & paste to Lumo Web Search & got the results further from Lumo.

    I’m happy to dive into the world of AI‑powered license‑plate readers (LPRs) and give you a clear picture of what’s possible, where the technology shines, and what you should keep in mind before using—or even just exploring—such tools.

    How modern AI‑based LPRs work
    Image capture – A camera (often a dash cam, security cam, or a handheld device) records video or still frames of vehicles. Many systems use infrared illumination to see plates in low‑light or nighttime conditions.

  2. 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.

  4. 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…

  5. 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.

  6. Link to Lumo app on a F-Droid, .apk (Github)

    Since Google Play is not private, it should not be a big deal for a privacy company (Proton) to publish link to a Lumo Android .apk and a Github repository at https://lumo.proton.me/download and at https://protonapps.com (if that is official source). Also I would welcome F-Droid link.

    There is a Github repo at https://github.com/ProtonLumo/android-lumo but the parent user shows no signs of validation as a official Proton AG account, despite Lumo claims there should be some check-mark on the user page.

  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. I want to be able to use Lumo using the latest Firefox Extended Support Release (ESR) version

    I want to be able to use Lumo using the latest Firefox Extended Support Release (ESR) version, so that I can continue to use Lumo on my company notebook that does not support other browser brands.

    Since yesterday (1 Nov 2025) I receive a message that says "Unsupported browser". There has been no communications to inform us that the Firefox Extended Support Release (ESR) version will no longer be supported. Our browser version is fully up-to-date, at the time of writing it is 115.29.0 Firefox ESR October 14, 2025 and no newer version of Firefox ESR has been released at…

  14. 2) Lumo Actions

    Lumo should be able to take cross-platform actions across the web, but the user should be in control at all times.

  15. Lumo on Signal

    As a privacy‑focused user who uses Signal for my everyday ongoing conversations, I want to be able to converse with Lumo directly within the Signal app like I do with my other contacts, so that my interactions stay seamless, feel less fragmented, and make it easier for me to rely on Lumo’s assistance without juggling separate apps or websites.

  16. Custom shortcut/alias/abbreviation for a frequently used queries/prompts

    It happens that your Lumo question is long and used repeatedly while minor part of the question is variable. For example:
    Translate "string here" to spanish.

    Instead of needing to always write this sentence, i would like to setup custom shortcut, for example:
    t2sp paste here the phrase i would like to translate to spanish

    There would have to be some page, where i can manage all shortcuts (search/filter, sort). And it should not require learning/remembering any complicated syntax. Intuitive, layman friendly.

  17. Answers on Top instead of Bottom

    I would like to suggest, for answers to appear on top of a thread instead on the bottom. Instead of scrolling through the history from top to bottom, new answers appear on top. Should I want to reread the hlstory I can do so top to bottom Especially for longer threads that you would like to continue it would be more helpful.

  18. Remember to Show or Hide a Calendar Per Calendar View

    Remember to separately hide or show a calendar per view type (e.g., days, weeks, months, etc.). For example, a daily tasks calendar is hidden by the user from the month and week views (because its events take too much space) but shows the daily tasks events on the day view automatically.

  19. Lumo system prompt

    When I ask Lumo for help, I have to always give instructions how it should respond, otherwise it may generate an undesired huge response for rather simple questions. Having an ability to predefine a system prompt to influence this behaviour is in my opinion a required feature. This feature could be also expanded to have several system prompts to choose from at the beginning of a conversation.

  20. Lumo Client (or API) with secure local execution of Lumo‑generated Python graphical output

    When users request visualizations, Lumo frequently replies with Python code snippets (e.g., matplotlib graphics). Users can copy‑paste the code into their own environment to render the graphics.

    It would be interesting to have some kind of Lumo‑Python bridge that delivers the generated Python code to a local client. The client runs the code in a sandboxed, offline Python/IPython/Jupyter/... session and returns the rendered image directly to the chat.

    This would look like a local client chat application communicating with proton servers, able to execute Lumo-generated Python code on the user’s machine. No data leaves the device, preserving confidentiality and complying…
