Highlight‑to‑Answer Feature
Add a capability that lets the user highlight (select) any fragment of text in the chat and then have Lumo generate a response that is explicitly focused on that highlighted portion. This makes clarifying questions, getting quick explanations, and avoiding unnecessary back‑and‑forth much easier.

ghost mode (and/or web search) saved
Hi there,
after I started using Lumo for a while, I like to use the ghost mode by default. However, under current setting (both on webpage and on Android app) I have to switch Lumo to ghost mode (and turn on web search) every time. Can we make it a setting to use the ghost mode (and/or web search) by default? It will save a lot of effort.
Thanks.
By the way, I like Lumo very much. After I found it, it became my main AI assistance.

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.

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.

Code blocks with syntax highlighting
I think Lumo could benefit from code blocks (similar to what Claude has) that have syntax highlighting. Lumo already supports some Markdown syntax features, so it would make sense to add code blocks that are made up of the triple backticks with an optional language next to the starting backticks.
I currently find it very hard to add code to Lumo when asking for information, debugging, or code edits.

Add "Default digital assistant app" capability on Android
Android has the option to change your default assistant app. Proton should add this capability for Lumo. A partial screen view of the app might be necessary for this to work smoothly as well.

Add support for de-googled devices
Lumo is unsupported without Google Play Services. Can't start the application, blocked during boot.

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.

Option to change avatar
I wanted to suggest adding an option to customise or hide the default cat avatar. I'm not much of a cat person, so having the ability to change or turn it off entirely would be a great improvement.

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,…

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.

Disclose weekly limits
At present, Lumo has a weekly limit on the free tier. The problem is, a user has no idea what this limit is, and only find out when they hit it. They also don't know what it'd reset. Proton should be providing transparency on this, not just a "surprise, you hit quota, buy or come back after some undisclosed period of time".

Allow anonymous data sharing
I know that Proton doesn't create/train its own AI model, but a good european alternative would be nice to see. As unpleasant as this might be, to create a good model, lots of data is needed. A great app is worth nothing without good models. The current market leader, openAI, uses user data to train their models and have a huge advantage.
If my data is ever used for training, I want to give it to a company I trust (or think I can trust) to handle them carefully. And this is you. I would like to see the option…

Learning Feature on Lumo
I would love to see Lumo receive a learning feature similar to ChatGPT or other AI tools. The idea would be that Lumo could help users study by generating learning materials such as quizzes, flashcards, or practice exercises automatically based on input. This would make Proton not only a privacy-focused productivity suite but also a helpful tool for education and personal development. Adding such a feature would make Lumo far more versatile and improve its value for students and lifelong learners.

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

VSCode integration
Other LLM's like ChatGPT and Claude have integration with VSCode. It would be great to see an integration for that or another opensource IDE.
The most amazing thing would be if you can replace all the things most people use day to day with apps and have full support on Linux.

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…8 votes
