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.

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…

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…11 votes -
Creation of Lumo Browser Extension
As a leading privacy AI, it's important that the chatbot can interact with our daily lives safely and privately. The addition of a browser extension for Lumo to interact with your screen would greatly benefit the greater Proton community.

I would like Lumo to have a possibility to choose cat from few possible themed variations, for example associated with seasons, birthdays, feasts, etc.

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.

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.

RAG my proton drive. Make Lumo be able to chat with me about my files.
I bought into Lumo and upgraded my proton drive as I had the impression that I could query my files.
In fact, I can only upload some of them. Well, some, in fact only 10Mb before it complains. Then if I leave the chat and come back, it seems to have forgotten I uploaded a file to chat with.Here is my use case which is currently available in CoPilot.
1. Have an option for Lumo to chunk and ingest the files in my drive.
2. Allow me to query them like a proper RAG systemThanks.

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.

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.

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)4 votes -
one click scroll down to most recent messages (mobile and desktop)
Currently you cannot easily scroll to the most recent answer in a conversation, it's particularly difficult on mobile. The app opens a conversation at the top, on the first query posted to Lumo. You can click the down arrow icon which scrolls partially but not to the bottom necessarily. So for very long conversations it often requires a lot of clicking or dragging of the scroll bar to get to the most recent message in conversation.
Even if you enter a new query it doesn't automatically view the most recent answer (there's a separate User Voice idea for that). Instead…

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.

Enable Lumo to Integrate with iOS MCP Mode for Voice Assistant Capabilities
In the recently released developer beta of iOS 26.1, references were discovered in the system files indicating that Apple is preparing support for MCP (Model Context Protocol). While Apple has not officially announced this feature yet, these findings strongly suggest that MCP integration is coming soon.
This presents an exciting opportunity for Proton to make Lumo more powerful and accessible by enabling it to function as a third-party AI voice assistant within iOS. Users could directly invoke Lumo at the system level, similar to Siri, but with Proton’s strong emphasis on privacy and security.
Why this matters:
- Privacy-first alternative:…8 votes -
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

Live Translation Capabilities For Lumo
Lumo, as a private AI, is primed to be an excellent assistant for users to have in their daily lives. This includes the ability to accurately translate pages and other media for the user, without compromising their media data, metadata, and contributing to the data collection of other larger and gluttonous chatbots that have this capability, like Google Gemini and OpenAI's ChatGPT.

Moving chats to/between projects
It would be extremely helpful to be able to move chats to/between project folders. I usually don't have the foresight to know when something will be big enough to be a project, or I might change my mind in the future and reorganize projects. Not being able to move existing chats that have been really helpful is extremely limiting, and doesn't incentivize me to to use the Projects feature at all despite how messy my existing chat history is.

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.
