Ability to affect the model choice
Especially for paying power users, it would be nice to have the ability to manually affect the choice between models. I understand if this doesn't fit your service framework, but I wanted to just put this out there.

Date and time in responses
Lumo doesn't give any indication of the time of the response. This is missing if one looks at later responses. And in general, it's good to time stamp events;-)

Make it possible for Lumo to interact (via an dedicated Proton AI agent) with all your apps within the Proton Suite
E.g.
I want to tell Lumo that it should add the vacation details of the last Protonmail I've received to my Proton calendar
update a specific proton Sheet with the latest information I give it (add a number to a column)
show me photos of my vacation in October last year (e.g. only selfie photos)
ask when my Proton subscription will expire.
etc
The idea is to have one Proton app to manage your entire Proton suite. Like a secretary. ofc you would need to set up everything separately.
To think this even further, make it possible to integrate Lumo…

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…

Extend Lumo to have integrated TTS/STT for full Voice Interaction
For general Chat, its really nice to be able to have a conversation using voice rather than keyboard. And while I know that the Android/IOS apps offers STT, its unfortunate that I have to use the phones TTS to complete the loop. For my tablet and/or webbrowser a full TTS/STT feature would be nice.

Ability to rename conversations with Lumo
I can do this with ChatGPT and Deepseek, but not with Lumo, and it's a lot better to have a short concise way to ID my conversations rather and a string of text that is hidden because I keep lumo on a smaller window.

Add a usage tab to Lumo
Lumo should provide a dedicated usage tab where users can see their daily resource consumption in real time, including Max model requests, image generations, and any other rate-limited features.
Lumo enforces daily limits on features like the Max model and image generations, but these limits are not surfaced to the user. The only feedback is an automatic fallback from Max to Lite when the daily Max cap is reached. Users have no way to check how much of their quota they've used or how much remains, making it difficult to manage their own consumption throughout the day.
It would be…

Lumo does not support uploading .png files.
Uploading image files is critical nowadays and lumo does not support .png files in order to analyse it.

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?

Support for Libre Office file types
Most people I know use Libre office for much of their Office needs, as I do - is there any future plans to support Libre Office files? .odt, .ods, etc.

Voice Mode and Assistant
Lumo should support Voice Mode and Android Digital Assistant integration
Lumo would become much more useful with a voice conversation mode similar to Gemini or ChatGPT Voice.
It would also be great if Lumo could be set as the default Android Digital Assistant, allowing users to launch it via the power button or assistant gesture and use it hands-free like Google Assistant.For privacy-focused users already using the Proton ecosystem, this would be a fantastic alternative to Google's AI assistant. 👍

Add Lumo Plus to one of your bundle deals
Currently you can only pay for Lumo Plus as a standalone product. Would be nice if it could bundled with Proton Mail or different tier of Proton Unlimited

Support MCP Integration
Lumo should support the use of Model Context Protocol servers in a fashion similar to Claude Desktop. This should be done with DXT, the Desktop Extensions package format, for ease of support. It would be acceptable if Proton were to select a limited number of offerings in this area. There MUST be a developer option where we are permitted to use the direction JSON configuration and any available server, but this should be community forum supported, with no direct assistance from Proton.
I have been evaluating the offerings in this space the last two months and I released an MCP…

Add support for Skills
I suggest Proton Lumo adopt Skills from (for example, skills.sh) as a lightweight way to package predefined trusted, domain-specific knowledge into small, reusable text modules. In practice, a Skill gives Lumo a clearer “expert lens” for a given topic, so instead of offering broad generic answers, it can respond with guidance that is more grounded, consistent, and relevant to the user’s actual question.
This matters for Proton Lumo because users will judge the product on whether it feels genuinely helpful in everyday moments. Skills can make Lumo better at explaining complex topics in plain language, guiding people through sensitive or…

Feature Request: Integrate Lumo into Proton Docs for Intelligent Writing Assistance
Dear Proton team,
I’d like to propose adding Lumo as an integrated writing assistant within Proton Docs. By leveraging Lumo’s advanced language‑model capabilities, users could:
Automatically scan documents for grammatical errors, spelling mistakes, and style inconsistencies.
Receive contextual suggestions to improve clarity, tone, and overall readability.
Benefit from the same AI‑driven assistance currently offered by the Scribe assistant in Proton Mail, but applied directly to collaborative documents.
This integration would enhance the productivity of Proton Docs users, reinforce Proton’s commitment to privacy‑first AI tools, and create a seamless experience across the Proton ecosystem.

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 the15 votes -
Letting programmers use Lumo in a code editor
As a developer, I added extensions to my code editor. Some companies offer extensions to use their AI models directly in a code editor, like "Claude" extension in VS Code. Being able to work with the AI within the code editor is a huge time saver.
It would make Lumo an even more useful tool for programmers and help improve their workflow.
Could you make the same with Lumo?

Ability to run local models
Some small models are capable to run locally on phones. This would be great for privacy and also as a free alternative for the more powerful paid LLMs.
