Heads-up from loyal Proton Unlimited users. Fix the (no) Lumo Offer.
We’ve been with Proton for years—full subscribers, big fans, and true believers in the mission. That’s why we’re speaking up now.
TLDR:
We’re asking Proton to do right by its most loyal users:
→Offer a Lumo Plus free trial as part of Unlimited
→ Or give Unlimited a reasonable ongoing discountUnlimited doesn’t feel so unlimited anymore—without Lumo AI, the experience now feels unexpectedly gated.
This risks undermining trust in the Proton promise. But worse it may cause class actions from Unlimited subscribers.🔍 See our full breakdown receipts included:
We know Proton listens. That’s why we’ve written…

Support more file type
Right now file upload is very limited, I can't even upload screenshot images for lumo to process. File type is very specific right now, I think it only accepts .PNG while .png is not acceptable

Lumo - Consistent Web Search
Love the Web Search option in Lumo, would be great if you could trigger it to work consistently. Currently it is sporadic and says it is not meant for real-time search/results. This is limiting considering the training dataset is over 2 years old. Being able to reliably get up-to-date information is critical for evaluating current trends, events, research, etc.

Employ bigger models
The current offering of models is entirely composed of small models, which can work well for some tasks and is certainly efficient, but also makes the service unusable for more complicated tasks. For example, none of the models employ reasoning techniques.

Unlimited chat history
I totally understand the price of LLM as extra subscription but limiting the chat history to 7 days is really just an annoyance. For paying customers with 500GB disk space and possibility to save history locally on device there is really no reason to limit it in any way.
For free users history can be saved locally only as on https://duck.ai/ and for registered users it can be saved in the account's storage quota. For unlimited subscription with 500GB disk that is basically unlimited.

Make Lumo Android app 'less' or not dependend on Google play like your other apps.

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.

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.

It should be more aware of its own capabilities.
The model keeps telling me its capable of doing text-to-image, stating that theres a feature where there actually isnt one.

Lumo doesn't know it's a cat!
I asked Lumo if it was a cat and it denied outright that it was a purple cat. Poor Lumo.

Auto-scroll the view to the answer
After generating each answer, automatically scroll down a bit to show the start of the answer. This will save the user from having to scroll down every time to start reading.

Disclose weekly limits
At present, Lumo has a weekly limit on the free tier. The problem is, a user has no idea what this limit is, and only find out when they hit it. They also don't know what it'd reset. Proton should be providing transparency on this, not just a "surprise, you hit quota, buy or come back after some undisclosed period of time".

Make Lumo Less Dumb
As a paid Lumo subscriber, there's no kind way of putting this -- Lumo feels really dumb compared to any of the other mainstream LMMs. It struggles to follow and keep up with conversations once they exceed a handful of back-and-forth exchanges, it frequently hallucinates and confabulates, it gets easily confused to the point where I'm having to help it rather than it helping me, and it just generally feels like conversing with a well-meaning but addled, confused elderly person. As such, I use it sparingly to brainstorm ideas or just have quick chats but cannot rely on it for…

A setting which prevents the Enter/Return key from submitting the prompt
Often now, when I am in the flow of writing a prompt and I naturally press Enter for a new line I end up submitting the partially written prompt. I am aware I can use shift for a newline but I've enjoyed the ability to change this behaviour in other apps (like Slack) to work in my favour. I would love to see this option to appear in Lumo sometime!

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.

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.

Multiple Lumo agents
Now that its possible to personalize Lumo, I also wish for the opportunity to create multiple different Lumo Agents, so I could for example have one developer agent, one recipe agent and so on.

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:
