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.

Python interpreter
Hi there, I'm a Proton user from around 4–5 years. I consider myself an early adopter of new technologies, so I've been testing out ChatGPT, Gemini, and other variants of LLM chats. One of my main uses of them is as a researcher and engineer, so I want LLM that are robust, in the sense all a LLM can be robust and predictable. But, in the sense, I want a "translator" o a "meta-transpilator" that translate commands into actions to be performed. For example, the task "translate this from Spanish to Catalan", is in fact a direct task that involves…

Implement TEE-Based Confidential Computing for Lumo Inference
Feature Request: Implement TEE-Based Confidential Computing for Lumo Inference
SummaryLumo's current security model does not protect user prompts during inference — the window when plaintext is most exposed and most exploitable. This is not a theoretical concern; it is a documented architectural gap with a proven, production-ready solution that a direct competitor is already shipping.
The ProblemLumo's security model blog post dismisses inference-time privacy by framing the only alternative as homomorphic encryption (HE), correctly noting it is impractically slow. However, this framing is a false dichotomy.
As Proton's own documentation acknowledges:
…"prompts are asymmetrically encrypted so only the11 votes -
Lumo integration with Proton Meet for accessibility (live auto-captions)
Perhaps Lumo could be used in Meet to provide live captioning for hard of hearing/Deaf folks to be able to follow along.
Having a meeting platform that is a) affordable/free b) accessible and c) privacy-minded would be incredible. I haven't found a single platform that meets all of those criteria well, and if you make this happen, you would be giving the world a gift. Thanks!

Better transparency for Lumo answer - Show Groundedness, Factuality score per answer
Proton Lumo AI should not only be private, but also fair and transparent about its answers.
I propose adding simply statistics to each answer derived from the metadata that is already present. E.g. a single bar going from green to red that show the likelihood of an answer being well founded (groundedness score) or something similar to a F1 score. In my opinion this matches the transparency that Proton is providing for all its products. Similar to how Proton uses Open Source code, it should also aim for maximum transparency of Lumo AI answers. This makes Lumo even better than…11 votes -
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)11 votes -

Ease up on the censorship within Lumo
I am an AI enthusiast and engineer. I am not kidding when I say I have not been able to prompt Lumo ONE SINGLE TIME without it saying that it cannot help with whatever I am prompting it for.
If you EVER want to sell this to ANYONE (especially if you ever want to sell the API), you probably aught to take the route that Venice AI is taking and make it an uncensored (or less censored) model. I genuinely could mention something loosely interpret-able as criminal, and it wouldn't even bother to try and reason whether it is safe…

Multiple personalization settings
Would it be possible to add different personalization settings and switch between them depending on how lumo is being used?

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!

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.

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.

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.

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.

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,…

Import Chat to Project
I've already had a number of chats that I realized would be best in a dedicated Project, but there's no easy chat-import function. Thanks to Lumo's report, I see it's a privacy-protection feature, so I'm quite thankful for that. But at the same time, perhaps a good balance would be to have a selective-transfer function, we can cause check-boxes to appear beside all prompts, Lumo-replies, and chat-knowledge files, so we can choose what to copy and what to allow for deletion, then paste it into a Project?

Enable Lumo to run locally
Enable to run Lumo models locally on a computer or laptop, this would enable users to better handle private information, increace speeds (by not needing to have the data travel across the internet continuously) and reduce load on Proton servers.
This could happen with a standalone app or integrating it with other systems such as LM Studio or Msty Studio10 votes -
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.

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.

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.
