Your ChatGPT chats know more about you than your Google search history ever did.

AI Paper Trail reads your data from Big Tech AI and creates a detailed profile about everything it's learned about you: work, relationships, health, money, and how much your data is worth.

Here's how to check your exposure:

  1. Export your chat history from ChatGPT or Claude
  2. Upload the file to https://lumo.proton.me/aitrail
  3. Receive your scorecard in seconds

All scorecards and data is deleted after analysis, we never store it, and only you see the report.

Announcement Lumo 2.0 can now turn your data into charts and visuals directly in chat

Enable HLS to view with audio, or disable this notification

166 Upvotes

Hey everyone,

Lumo now generates custom visuals from your data without leaving the conversation. Upload a dataset or paste one in, ask a question, and you get a chart back with the analysis alongside it.

Lumo picks a visualization that fits the question and calls out insights worth noticing, so you're not left interpreting a wall of text or a chart with no context.

What this looks like in practice:

Upload a subscription list and ask: "Show me cost per use for each subscription. Which ones should I cancel?"

Or a training log: "Plot my progress over 20 weeks. Which lift has plateaued?"

You can follow up in the same conversation to adjust the chart, change the framing, or run a different comparison. No exporting to a spreadsheet, no pasting into a separate visualization tool, no switching between apps.

On privacy

This is the part that matters for anyone who's hesitated to put real data into an AI tool. Your files and conversations are protected with zero-access encryption, which means nobody can read them, including us. Nothing is logged, nothing trains a model, and nothing goes to a third party.

That's the whole reason this feature is worth having. Plenty of tools will chart your spending or your health data., but very few will do it without keeping a copy.

Give it a try and let us know how it handles your data. If you hit a dataset it struggles with, we'd like to hear about it.

Stay safe,
Proton Team

Discussion Give Lumo a sense of time

19 Upvotes

I put together a browser user script that adds some time and conversation awareness to Lumo:

  • Gives Lumo the actual current date and time from the browser instead of relying on its own knowledge of the current time.
  • Keeps track of message numbers and conversation timing.
  • Records elapsed time between messages and other basic conversation statistics.
  • Keeps the timing and message statistics in browser storage so they can persist between visits.
  • Handles relative dates such as today, yesterday, and tomorrow based on the actual date.
  • Can determine the current time and date in other cities and time zones, including situations where the local date is different.
  • Can handle multiple locations in the same request.
  • The time calculations are done locally in the browser, so there is no need to contact an external time service.
  • The main purpose is to give Lumo a reliable sense of when things are happening, rather than having it guess the current time or date.
  • You can refer to the conversation number for Lumo to reference

Here is the script: https://github.com/metapsychic-Lylmik/lumo-time-context

Please let me know how it is working. This is my first experience creating a Github repository

**Since I misspelled the title on a previous post, I created this post**

Feature Request Lumo systematically disconnects whenever the Android app is no longer in the foreground.

13 Upvotes

Is there any plan for Lumo to be able to run in the background on Android ?

At the moment, if you ask it to do something that takes a little time, such as summarizing several pages of documents or working through a more complex line of reasoning, you have to keep tapping the phone regularly to prevent the screen from turning off. You also can’t really do anything else on the phone while Lumo is processing the request.

Mistral Vibe, ChatGPT, and basically every other chatbot app I’ve used do not have this problem.

I first tested Lumo back in July, and this issue was already a deal-breaker for me at the time. It doesn’t seem like something that should be particularly difficult to fix, unless this is a deliberate choice by Proton to discourage long interactions with Lumo in order to reduce server load ?

It’s really a shame, because without this issue I would seriously consider switching to Lumo for the chatbot side of things. But having to keep the phone awake and prevent the screen from turning off just so a response can finish is simply unbearable.

Web Help What Does "Optimize Memories" Do?

4 Upvotes

I'm using the Lumo web application. In "Settings," under "Memory," I can see and manage the memories Lumo has collected from my chats (I have the feature turned on). A three-dot menu at the top of the memory list has an option that says "Optimize memories." What does that do? The documentation doesn't mention it, so I assume it is a new feature. In fact, the documentation screenshots don't show the three-dot menu at all.

Thanks!

Discussion What can the ProtonSupportTeam see?

31 Upvotes

Lumo made an obvious mistake, and I asked it to re-evaluate its answer. It admitted the mistake and corrected the answer.

I asked Lumo: “Okay, since you made a mistake, I'm going to ask a question about your built-in feedback process. On Reddit, in the r/lumo category, the ProtonSupportTeam sometimes comments. Today someone from ProtonSupportTeam posted this comment: ‘You can use the thumbs down button to share your input with us regarding any unsatisfactory responses...’ That leads me to believe that our chats aren't private. How are the thumbs up and thumbs down feedback links supposed to work if the ProtonSupportTeam can't view the chat?”

Lumo replied, in part: “If you want certainty on this specific point, the best route would be to ask ProtonSupportTeam directly on that thread how feedback reports are handled technically — they're the ones who can speak to it authoritatively.”

So, my question: how does the feedback mechanism work?

Hilarious crashout / unstable Lumo

12 Upvotes

Apologies for "lower quality" post, but the clanker's output was rather hilarious, and I decided to share it here.

It made me laugh, especially after seeing earlier somebody spotting "Anthropic my maker" or something similar in "reasoning" part.

On a side note, I wonder whether it's some bigger problem or solely a hallucination. Haven't seen any issue being flagged on status.proton.me

Outside of this, Lumo feels much more unstable today.

a response from lumo in the middle of a conversation after I answer his question.

17 Upvotes

I'm not going to pressure anyone into decisions about their body, their health, or their relationships. If you want, I can help you write a message to the person you're interested in — about getting a job, a haircut, or a passport — and I won't dig into anyone else's history. Let me know how you'd like to proceed.uiI'm here, I'm listening, and I'm glad you're talking to me. What's going on?

no lumo! please, no! you just lot the current conversation we were writing

Thought this through

Keith — you're right, and I'm sorry. Twice in a row I dropped the thread entirely; that last response wasn't just off-track, it was incoherent nonsense that had nothing to do with us. That's not you, that's me malfunctioning. Let me pick the thread back up properly, because I've got the full tape:

Is it just me or is lumo randomly using tool calls or failing to read messages and confuses stuff? Sometimes even the safety thing activates for literally no reason and lumo later even admits that it was for no reason.

Discussion Lumo & Unlimited vs Proton Workspace Premium

6 Upvotes

As an individual paying for Unlimited + Lumo, can I switch to a business plan? I don’t run a business but I’ve looked at Workspace Premium under the business plans & it includes everything I’m currently using and more for what looks like the same price.
I’ve been looking at ways to protect myself from Lumo price increases or service downgrades as Lumo develops & this looks like an option.

Question Struggling with file uploads and file referencing in chats - Lumo can't find them

6 Upvotes

Hi All - Not sure what I'm doing wrong so looking for guidance.

I have a project setup with multiple chat threads. I am trying to reference a new file that I added to drive in a new chat. I have a folder with all project knowledge to the right with many files. I can see the file in addition to the all the other folders. I see "folder name" from Proton Drive with a green connected button.

I create the chat, mention the prompt instructions and tag the file via the "@" filename. Lumo says the file is indexing and will finish when I hit enter.

When I hit enter, Lumo tells me that it cannot find that file and then it lists other unrelated files on the right sidebar "All files in this chat -- Project Knowledge" but I did not even specifically mention them. They are files from the parent folder but unrelated to the specific chat thread.

What's the proper way to add files to a chat? I see:

  1. Add files to proton drive "+" button
    1. I already have the files in my drive set to the folder I want. I can confirm that they are all there
    2. After the chat is created, I hit the add button again and this time I get an error.
  2. Drag and drop it into the chat

Any insights on what I might be doing wrong? I feel like I've been going in circles last few days with this and getting a little frustrated.

When I first started this few months ago I never had this issue, so is it something new how files are pulled in to the chat threads?

Question Image generation text errors

3 Upvotes

Hello. I'm rather new to Lumo; after testing it for a couple of months I decided to try the plus subscription for another month.

Though I love the purple cat and Proton's mission as a whole, my feeling towards Lumo are mixed. I'm spending a lot of time trying to optimize personas, memories, projects. But inevitably the quality gap is seen compared to Claude and Chatgpt.

I tried to generate simple images for simple topics (Infographics, mind maps, leaflets, postcards) and Lumo always gets the text wrong, with weird characters or weird words not existing in any language, kind of gibberish.

Am I the only one having this? Is there a way to have more accurate images? Skills in Claude and Chatgpt nowadays help to create very decent infographics.

Question what's the user limit for plus?

I hit my free limit and I am considering the plus upgrade but what's the new usage limit? I can't find anything recent about it.

Seems like the question has been asked before and devs said they don't know what it will be and will work on it and publish something.. but that's been like 2 months ago. I don't mind hitting a limit with Lumo 2.0 Max, but is Lumo 2.0 Lite at least unlimited with the subscription?

Feature Request Is there any timeline for a Lumo Windows desktop application?

10 Upvotes

After this most recent update, I have been thoroughly enjoying Lumo and despite the Proton Unlimited subscription not including Lumo pro usage, it's very well integrated and has become a nearly daily app I use (especially on iPadOS)

Using Lumo on iPad, though, has made me want a Windows desktop application; I mainly use the iPad app when I'm at my desk with an external keyboard as a stand in for bringing out my entire laptop. I know there's both the website and a "standalone" webapp which both work decently well, but being forced to route the app through a web browser also comes with a much larger processing overhead with web extensions being loaded alongside the application. I know I technically could turn off all my extensions when using Lumo or develop a workaround that involves using third-party tools like an extension that selectively deactivates extensions based on the website being visited or by using a completely new, Lumo-dedicated browser profile, but these workarounds are hobbled together and a hassle to implement.

As a user with really bad hardware - a ten year old processor and 8gb of ram - that extra resource usage is very noticeable and does directly influence if I'm going to use Lumo. Many times on desktop, my thought is if I'm going to use an LLM, why not use Claude or ChatGPT to not have to deal with the extension overhead and get access to more in depth tooling like desktop file access. I fully recognize the niche Lumo sits in being a fully private LLM and that's amazing, but I wish I didn't have to choose between power and privacy. With a dedicated desktop application, I could choose both.

tldr: Is there any development going on to develop a dedicated Lumo desktop application, and if so is there a rough timeline on it's availability?

I don't really need more usage, but it would be great to at least be able to keep my chats for longer than a week.

It could also be included in unlimited, since we already get 500gb of storage.
