Let Lumo reference past chats & have memory
Hello Proton Team,
I would like to suggest adding a new feature to Lumo that allows it to collect personal information and interact with users in a manner similar to ChatGPT, but with a strong focus on privacy. The idea is to enable Lumo to understand and assist users by learning from their information, preferences, and interactions — all while ensuring that this data is fully private and protected via end-to-end encryption.
This would combine the convenience and intelligence of an AI assistant with Proton’s commitment to user privacy and security. It could open up new possibilities for personal productivity,…5 votes -
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…

Use better open-source ai models.
Dear Proton Team,
I would like to propose integrating several high-quality open-source AI models into the Lumo platform. These models align with Proton’s core values of privacy, transparency, and user data sovereignty, while offering excellent performance and flexibility.
The recommended models include GPT-OSS 120B, LLaMA 3, DeepSeek-V3, Mistral 8x22B, and BLOOM. These models stand out because they are open source, enabling complete self-hosting and customization. This means Proton can maintain full control over user data, keeping all processing within secured European data centers, aligned with Proton’s zero-access policy and strong privacy commitments.
GPT-OSS 120B offers powerful capabilities close to proprietary…

Personal Assistants / Preconfigured Prompts in Lumo
I’d like Lumo to support personal assistants or preconfigured prompts, similar to what Kagi Assistant and other AI tools already offer.
This would make it easier to switch between different roles (e.g., researcher, writer, teacher, developer) without having to retype or remember long instructions each time. It would also give users more control and flexibility to adapt Lumo to their own workflows.

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.

File types and size / unsupported file types
The current file types to upload f.e. images don’t work well and constantly I’ll get the message of “unsupported file type” in the pop-up window and that’s a false flag. They are all files types that Lumo support. I can open those files without any problems within Proton Drive or iCloud. Same issue occurs on Windows desktop, iPhone and iPad. Drag and drop makes no difference.
The file size is also an issue, limited to 10MB and I have a subscription. An average photo is already more than that. Files stored in Proton Drive can be uploaded with a maximum…

Feature Request: Exclusive Access to Larger LLMs for Lumo Plus Subscribers
I would like to propose a feature specifically for paying Lumo Plus subscribers: the ability to enable Lumo to use larger LLMs (such as GPT-5, GPT-5 Thinking, Gemini 2.5 Pro, Grok 4, Claude Sonnet 4.5, etc.) for processing queries. The core idea is for Lumo to act as a privacy barrier—protecting user data—while still taking advantage of the advanced capabilities of top-tier models for those who subscribe.
This enhanced feature should be strictly limited to users who actively pay for Lumo Plus. Free users would continue using the current models and would not have access to this option.

Lumo crashing on Android with No Google Play Store
Hi team. great work on launching lumo. on my android phone with no google playstore and only google play services running with limited access and internet access blocked by firewall, the lumo app crashes after a delay of a few seconds.
The error reads
'Something went wrong.
Check that Google Play is enabled on your device and that you're using an up-to-date version before opening the app...'all other proton apps work fine on my phone

Add “Auto‑Enable Web Search” Setting for Lumo Chats
Introduce a new option in Lumo’s Settings—“Auto‑Enable Web Search” (or a similarly named toggle). When activated, Lumo would automatically turn on the web‑search capability at the start of every new conversation, eliminating the need for users to manually enable it for each chat session.
Why This Matters:
Seamless Experience: Users who rely on up‑to‑date information can get instant, real‑time answers without an extra step, making interactions feel more natural and efficient.
Consistency: Guarantees that all chats benefit from the latest data, especially for topics that change frequently (news, weather, stock prices, etc.).
Time Savings: Reduces repetitive actions for power users…

Lumo Conversation Mode
It would be amazing for Lumo to have a full conversation mode, similar to other LLM apps, where you are able to speak to Lumo, Lumo will realize you are done speaking and reply, and then wait for your next reply...etc.

Make it easier to navigate. I have quite some open queries that I go back to and at least on firefox it is very hard to find the slider
The slider on the side is really hard to find when you have a long query. But I would like to go up and down to see earlier answers and it is really hard to do. Not even the middle button (roll) on the mouse works to go up and down.

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:…17 votes -
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.

Dynamically load files from Proton Drive folder instead of file upload
Please offer the option to point to a folder on Proton Drive. That would be much more flexible instead of uploading new files each time.

Toggle to volunteer to help improve lumos language model
This would be opt in. If the user agreed, then warnings and such would be provided. The user would decide what information to volunteer, but certain information types would be restricted to protect the users privacy and to not compromise the values that proton is built upon. Also, proton or whoever maintains the ai language info/etc..., would have the final say before any volunteered info would be added. The exact way of doing this would need very careful considerations.

Dark app icon for Lumo
All the other Proton apps have an icon for light and dark mode. I think it would be great to have a dark icon for Lumo since it only has a light icon.
