Really needs image OCR
There are a lot of image processing requests here. All basically requesting the same thing with different wording. Moderators should combine them to increase the votes. Basically we need Optical Character Recognition for uploaded images, and some PDFs that contain bitmaps. On a cell phone, this is critical and the primary reason I rarely use lumo. Being able to upload a screenshot of a log file, or a code routine, or a medical lab result and have it convert to text and analyze it is really needed. Every other big name model has this ability, but I am sure you…

Please add automatic calendar for displaying contact birthdays. This is a feature in Google Calendar and is the only reason I still hang on to that app

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.

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

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…13 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.

Stand‑alone Lumo Windows Application
Create a native Lumo desktop client for Windows that delivers the full Lumo experience—chat, writing assistance, file uploads, and secure conversation management—without requiring a browser. A dedicated Windows app would let users keep Lumo open alongside other productivity tools, benefit from hardware‑accelerated rendering and system‑level notifications, and integrate with Windows credential storage to preserve zero‑access encryption. It could also cache recent conversation history locally for offline read‑only access and provide a system‑tray icon with quick‑launch and status indicators. The first release should mirror the web app’s feature set, offer a Windows‑styled UI (dark/light mode, resizable windows, snap‑assist), support automatic signed…

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…

Using better open-source/weight AI Models
Hi everyone,
I am writing this because I think Lumo has so much more potential. Imagine them using a 1 trillion parameter Chinese open-source/weight AI model like it would give them so much more flexibility in new features and accuracy of up-to-date data. They could even train an own AI model that they can then use like OpenAI uses ChatGPT as an multimodal AI model without having to rely on others creating open-source/weight AI models for them to use plus they could customize it perfectly for privacy, speed and accuracy. This own AI model could be based of some other…

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

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.

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.
