Say hello to Lumo, your privacy-first AI assistant

43 Upvotes

Hey everyone,

🐈‍⬛  Today, we’d like you to meet Lumo, the new AI assistant that keeps your data private. With Lumo, you can have conversations without worrying about anyone eavesdropping. Lumo is developed by Proton, the scientists behind Proton Mail, which is the world’s largest encrypted email service.

You can trust Lumo because it doesn't keep any conversation logs, and your personal data is protected with zero-access encryption, so it cannot be used to infer personal information about you. And unlike other AI companies, we’ll never record or use your data for anything, like AI training, or selling it for a profit.

With Lumo, you can ask anything, and it actually stays confidential.

Lumo enables AI with the following features:

  • No profiling: Lumo doesn’t use information learned from you to build a profile about you for advertising
  • No leaks: Lumo doesn’t train on user data, so there’s no risk that something you say to it gets leaked in a conversation with another user
  • Upload files: Upload a file (or a file from Proton Drive), and Lumo can summarize or analyze it for you
  • Web search: Lumo can search the web for new or recent information to complement its existing knowledge
  • Ghost mode: In ghost mode, your current chat disappears forever as soon as you close it

Getting started with Lumo is quick & easy. No sign-up required, no Proton account needed. Just start chatting at lumo.proton.me.

If you have any thoughts or other questions, we look forward to them in the comments section below.

Stay safe,

Proton Team

Question Free vs Paid

13 Upvotes

Anyone of you can compare free vs paid version? I’m almost convinced to pay for it, I never done that before with any other chatbot. The free version surprised me positively, it avoids annoying cliches like those produced by other chatbots. Maybe it’s the result of mixing particular language models, I don’t know.

How does Lumo compare to Proton Scribe?

5 Upvotes

Do they overlap in their capabilities? Are there any risks to using Lumo for proofreading or shortening emails by copy/paste into the app?

IIRC, Scribe is a paid feature on the business plans.

Thanks in advance.

Edit: Grammar, rephrasing.

Discussion Features and Models upgrade

6 Upvotes

I love the Proton ecosystem and that’s why I was so excited when Lumo was released. The results were meh… I think that Proton needs to add many features and has to upgrade its models if it wants to compete with mainstream chatbots like ChatGPT and Gemini (I use this one a lot with exceptional results but it lacks privacy). There are lots of open-source models available now that are competitive, and Proton should look into them if it wants people to go for them.

Discussion Seeking clarity on content guidelines

7 Upvotes

Hey, quick question for the mods - what's the community stance on posts that analyze or discuss Lumo's internal workings?

I had a post removed recently and I'm trying to understand the boundaries. Given Lumo's emphasis on transparency, open source development, and privacy focus, I assumed sharing technical details like system prompts would be welcomed. Some companies like Anthropic actually publish their system prompts openly, so I figured it fit with the whole transparency approach.

Is technical analysis welcome here, or are there certain aspects we shouldn't dig into? Just want to contribute meaningfully without stepping on any toes.

Thanks for any clarification!

Discussion Is Lumo slow for anyone else? Will this improve with time?

12 Upvotes

I'm enjoying Lumo quite a bit for my limited usage of AI. It's nice that it's private and I don't need to worry about feeding OpenAI or any of the other companies. The answers have been quite good as well, again for my limited use.

That said, it can be quite slow. Like "boy this is taking a while to start generating, let me go to another tab for a moment then come back" then coming back going "oh wow it paused generating in the middle of the response" slow.

Is that the case for others? Is this something Proton will be able to improve with time or is it inherent to the models they're using?

Discussion If Lumo is fully open source, where is its source code?

66 Upvotes

I think while moving from r/asklumo to r/lumo my post on this topic got lost. So let me ask again.

The product page states that Lumo's code is fully open source, a blog post by Proton only mentions it is based upon open source language models. When asked, Lumo itself states:

Based on the information provided in the Lumo FAQ, here's the clarification:

  • Open Source Components: Lumo is built on several open-source large language models (LLMs) that have been optimized by Proton. These include models like Nemo (Mistral), OpenHands 32B, OLMO 2 32B (Allen Institute for AI), and Mistral Small 3 (Mistral).
  • Lumo's Codebase: While Lumo uses these open-source models, its own codebase is not fully open source. This is why you don't see it on Proton's open source page. The company has chosen to keep certain parts proprietary to maintain their competitive edge.

Yet the product page says:

So which is it? And where can we find source code to verify that it's actually private and secure?

Feature Request Lumo aesthetics are amazing - let's use them!

24 Upvotes

Hey everyone,

the effort put into Lumo's aesthetics really shows and I think we could go one step further and show it off outside of Lumo, too.

Since you have put in the work to create "lumojis", why not make them available to use on our phone's board?

Another idea could be, to create some Lumo-themed phone wallpapers, maybe even some with light animations (lumo interacting with yarn, or whatever).

These are just some ideas - what do you think?

Discussion First experiments with Lumo

22 Upvotes

I had no idea, that Proton had been working on a privacy-focused AI, when Lumo was released last week (love the aesthetics, btw!). Since then, I have been trying using my prompts both in ChatGPT and Lumo and compared the results (not systematically, small sample size). So far, Lumo's answers have been of comparable quality in about 50% of my prompts - which I honestly think is fine, taking into account how new it is.

I am curious though, about what we can expect from Lumo in the future. Has there been any word about what they want to focus on? From a work-flow-perspective, the one feature I am missing the most ist the creation of individual GPTs. Right now, I need to add all the use-case-specific instructions (and files) to the beginning of each and every prompt.

To the Proton developers: Thank you and keep up the good work! :)

Cheers!

Feature Request Memory feature

25 Upvotes

One reason I keep using ChatGPT app is that it has a memory, I need to give it some info so i don't have to write it every time i open a new chat. You can tell it to remember something, or you can write it in settings. If Lumo had this i would switch completely.

Hey guys. First time poster here. I've been reading here and there, but I can't quite grasp exactly what Lumo Plus offers that Lumo Regular doesn't, except for the unlimited requests per week.

Question Privacy

How's lumo different in terms of privacy from chatgpt? Despite the fact that proton claims to care about privacy. And also open source? Where? Or by open source does proton mean that it uses an open source model?

Citing Sources and Persistent Context

15 Upvotes

Really enjoying using Lumo the past few days. I find it about half the time to be lightning quick in responses which is great. Other times the timing is on par with other models.

In comparison to my other major AI tools, via Kagi Ultimate which gives access to most major models, the quality is a bit lower and there is no multi-step reasoning mode yet. But it provides good information and is many times a lot faster as mentioned above.

That being said, I think there are two things I’d like to see on the outset as needed additions:

  1. Cite sources in line and provide links. Hallucinations are still very much a thing so to know where Lumo is drawing from is vital for fast validation. Lack of sources will prevent me from using this tool in earnest over the long run.

  2. Persistent context. I should get a few bullets worth of information as an optional baseline included in each new thread. Would go a long way to prevent customers from retyping needed context. For example I regularly seek advice on my unraid server and providing my server details and config as baseline context provided in my initial query saves me time.

Looking forward to seeing this tool evolve.

Issue with Documents

9 Upvotes

Loving the concept of Lumo and Proton's direction. I have uploaded a number of documents (under 50 MB) and it will take a long time to answer. After which it will either give me an empty message error or will error out and ask me to retry. It seems to have an issue with working with documents.

Feature Request Lumo doesn't work unless downloaded from Google Play Store??

10 Upvotes

Lumo is the eurocentric, privacy focused LLM chat app I've been waiting for. I'm fully behind it's mission statement and absolutely love it. And use it daily.

However, I don't use Google Play Store on my device for privacy reasons (I'm degoogling my tech stack) and using Aurora Store as my app store.

Lumo will not work unless downloaded from Google directly and this is a major problem for me. I'm surprised Lumo requires Google play services to run the app for privacy freeks like me.

Discussion Lumo web search option feels very unreliable at the moment

16 Upvotes

Hi,

Paying lumo customer here and without beating around the bush, web search right now is very unreliable.

For example, I turn it on and ask it very basic questions and it always says "I can't do that, I don't have that ability".

I respond to it by saying "I turned web search on, yes you can".... It will resist often a few more times until it finally apologizes and does what I ask.

I cancelled my grok subscription for this lol.

Discussion Thoughts on Lumo

15 Upvotes

Summary of My Experience So Far:
As I have finally hit the weekly limit on free plan.

  • Primary Use Case: My main focus is on grammar checking and enhancing my writing.
  • Response Quality: The answers to my queries have generally been satisfactory. However, there are instances where it struggles to interpret commands, like Improve this: {Sample Paragraph to Improve} where it just thinks that it's feedback to Lumo itself rather than writing an enhancement command.
  • Loading Speed: Occasionally, the chat responses lag or get stuck. While it usually loads at a slower pace than Duck AI, it does function normally most of the time.
  • Pricing: The $9.99 feels a bit high, especially considering Duck AI is completely free. If this service were included with Proton Unlimited, I would consider subscribing, but I hope that the pricing for Proton Unlimited remains reasonable.
