  2. Some replies are unnecessarily long / Make shorter replies

    Quite often Lumo is longer in its replies than I would like to. I can always ask Lumo to be short, but it is a bit annoying.

    A) Can there be some switch near the prompt where i can single click to change length of the reply? (my last choice would be remembered or in a Settings would be an option where I can override this so it always resets to a mine defined default length)
    B) Make the replies shorter and add a button at the end of the reply, where i can click to let Lumo return more…

  3. Add models for creative writing

    None of the models Lumo uses are very good at creative writing. Please add a model that can provide helpful writing critiques, ideas, etc., for creative uses such as storytelling, poetry, songwriting, and creative non-fiction.

  4. Customize Response

    I'd love to see a "Customize Response" button like duck.ai has. It basically lets you tweak the prompt without having to type out everything every time you start a new chat. The idea is sort of similar to https://protonmail.uservoice.com/forums/932842-lumo/suggestions/50343312-memory-or-knowledge-functionality-for-lumo, but not quite. I think this idea is a bit easier to implement.

  5. Lumo integration in meet for meeting summaries & transcriptions

    It would be great if the upcoming meet app would have an option to summarize and transcript meetings.
    Making this possible with a trustful AI like Lumo would be amazing (and I think no one else has a meeting transcription feature with a trustful AI)

  6. 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.

  8. Allow external files as data sources

    It's annoying that I have to download publicly available files in order to upload to a Lumo session. Since you have a web search option, I know you have access to the web. Please add functionality that allows us to point to URLs to use as data sources. For example, I have some markdown files in my public GitHub repos i would like to use as a data source

  9. public URL parameter that pre‑loads a specific prompt

    It would be nice to have a public URL parameter that pre‑loads a specific prompt, such as https://lumo.proton.me&q=my_specific_prompt because this would make it possible to define "search"-shortcuts in Browsers or for example in krunner under Linux to open Lumo directly with a starting-prompt.

  10. Feedback on Conversation Restrictions

    I value Lumo’s privacy-first approach and commitment to respectful dialogue, but I feel that the conversation restrictions and automated content moderation make it frustrating to use for honest adult discussion. Too often, it feels less like I’m talking to a smart assistant and more like I’m conversing with a cautious PR department or a nervous nun—avoiding anything remotely challenging or controversial.

    Real conversation and learning require engagement on sensitive, nuanced topics (like politics, social justice, religion and world affairs). Instead, Lumo shuts down or blocks the session whenever certain keywords or contentious issues are mentioned—even if the conversation is thoughtful,…

  11. Create tentative/optional events in Calendar

    I need to track events where my attendance is optional, and I may be the creator of that event.

    If I get an invitation to which I have not replied, the event is marked tentative, but if I create it that is not an option. It should be.

  12. Android Intent Support or API for a Reading App Integration

    Dear Lumo Team,
    I'm the developer of @Voice Aloud Reader, a popular Android ebook/document reader app. I'm interested in integrating AI-powered book summarization features that respect user privacy - which makes Lumo an ideal solution.

    Current Approach & Results: I've tested Lumo with book chapters (up to 100KB text) by manually copying/pasting content. The summarization quality and literary analysis are excellent - exactly what my users need for "remind me what happened" scenarios when returning to books after breaks, having questions to answer, discuss the book etc., but copy/paste workflow is far from perfect.

    Feature Requests:
    1. Intent.ACTION_SEND Support: Allow…

  13. Make Lumo Less Dumb

    As a paid Lumo subscriber, there's no kind way of putting this -- Lumo feels really dumb compared to any of the other mainstream LMMs. It struggles to follow and keep up with conversations once they exceed a handful of back-and-forth exchanges, it frequently hallucinates and confabulates, it gets easily confused to the point where I'm having to help it rather than it helping me, and it just generally feels like conversing with a well-meaning but addled, confused elderly person. As such, I use it sparingly to brainstorm ideas or just have quick chats but cannot rely on it for…

  14. Multiple windows (both emails and calendar) on Windows

    When using ProtonMail, I want to be able to:
    - Open a specific email in a new (secondary) window, So that I can read that email and type in a new email in a different window.
    - Open the calendar in a new (secondary) window, So that I can look at my calender while processing emails.
    - Open multiple emails in one window each.
    - Open multiple calendar views in one window each.

    All this is possible in the WEB version, but I need to use the full search feature of the local installed ProtonMail client.

  15. Better Mathematical Expression Display

    Currently, the mathematical expressions produced by Lumo in responses, are not legible. They are generally in raw latex syntax, which is absolutely unsuited for display purposes. They should be rendered either as legible plain text (probably bold-faced for distinctiveness) or as document-typeset graphic math expressions.

  16. 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!

    Add a button where I can hear the answer being read out loud. Make it be able to play in the background. Like in Perplexity.

  18. Do not format user inputs

    Currently, in Lumo my user input is formatted in e.g. markdown when the app "recognizes" that it is markdown. However, it is not. I am working with files that have comments at the top starting with # and it is falsy detected as markdown. Please keep the user input as raw text.

  19. Let Lumo export a single answer as PDF file, not as markdown script

    Dear support team, please consider adding the feature to export answers, which are sometimes in form of tables or checklists.

  20. Lumo Branding / Design

    Lumo Logo / Design / Branding

    Suggesting an overhaul and alignment with the Proton family of product.

    The current choice has no cohesion with the established design language.
    Unless it is design for an audience of kids and adolescents specifically it feels
    playful, cute and disjointed.

    Surely kids and adolescents are not the primary market for the company's
    flagship AI product. Given the importance and relevance of AI a bit more
    thought could very well go into the branding here.

    As huge Proton fan and customer of many years I frequently wonder about
    the design choices. Form, function and aesthetic…
