Improving response quality and reducing bias
As it is, Lumo doesn't work very well.
It hallucinates facts more often than other modern models that also don't access the web. When asked about privacy-related questions, it almost always promotes Proton's services (including ones that don't exist such as "Proton Chat"). I understand that there is an incentive to promote the company's own services, but most people interested in a privacy-respecting LLM, and especially those willing to pay, don't want it to act as a shill for Proton.

Accept all text files, independently of their extension name.
Lumo is able to read and understand many text-based files (LaTeX, json, python, etc...). However, only .txt files can be uploaded (files without .txt extension name are refused). It would be nice to accept a larger set of file, as Lumo is able to read them once renamed with a .txt. Lumo shall be able to recognize them correctly, without enforcing in the chat was format is intended to be the submitted file.

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…

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…

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.

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.

"Terse" mode or "conversational" mode
I often don't need 3-page instructions and checklists on the topic I've asked a question about. For example, it recently gave me instructions on how to set up an email. It can be a bit overwhelming and difficult to go back to important information in the conversation.

An option to keep list of conversations always visible
Currently the left sidebar is collapsed by default and past conversations aren't visible. There is a button, that expands it, however that expanded state doesn't persist between reloads, and the next time Lumo is opened, it's collapsed again. For someone who returns to previous chats frequently it's a must have.

Allow reporting of long requests
Lumo already allows rating the feedback of the model. However, it seems to be limited to 5000 characters, which is often not enough for my requests, making it impossible to report wrong responses. Please extend/remove this limit.

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.

LUMO+ with Access to Multiple AI Models
I’d like to suggest an improvement to LUMO+. Currently, LUMO+ is great, but it would be even more powerful if it worked more like Perplexity Pro, where subscribers can access multiple AI models like GPT-5 or Gemini 2.5 Pro, including those for image and video generation.
The key idea is that LUMO would remain the secure privacy layer between the user and these external models. This way, LUMO could either answer directly or automatically choose another model when it’s better suited for the request—without exposing any private data or the user’s identity. Everything would remain protected under Proton’s privacy-first approach.

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.

In Lumo, re-label the entry box as "Question or Response", as it has to be used to respond to choices offered by the search.

Real‑time audio conversation
One of the features I was using—and I see people using—is audio‑based conversation with the models. The main goal is to practice languages by asking the model to simulate a dialogue, then receiving feedback and corrections. This is a feature I would love to have in Lumo, because I don’t feel comfortable sharing my voice with Big‑Tech models or companies that don’t respect privacy.

Please make expanding the sidebar persist across sessions
Please make expanding the sidebar persist across sessions, I don't want to ~unhide it every time I go into it.
