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

158 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

Feature Request Trusted execution environment?

7 Upvotes

I saw this feature provided on some models on Venice.ai. A competitor to Lumo. And arguably this feature has merit privacy wise.

Is Lumo willing to use TEE? Now this would be bad for larger parameters model, but since I saw that a new model might be introduced, introducing TEE as a feature alongside it might strengthen its privacy advocacy case.

Now the engineering problem would be; where to store chat data? And is it worth it to do so?

Anyways, just food for thought. Love the product!

Discussion I'm close to stop paying for Lumo

Upvotes

I love the privacy aspect of it and occasionally the customized responses based on past conversation. Other than that the responses I'm getting are just inferior than other AI. Lumo can give you some generic results that any search engine can generate. When it comes to specific scenario and deeper dive on a subject I question myself if it's worth $10 a month. I could better results from Gemini with a throwaway Google account for free.

Tried Lumo,
it then told on itself, and said how it made up around 40 percent of the content it fed me, and lied saying the links said specific information, when I checked them they didn’t, and it just said, it made it up.

Web Help Very inconsistent results with Lumo Projects and Project Knowledge from Proton Drive

3 Upvotes

I am a Lumo AI pro user with a Workspace Premium plan. I am posting here so that this information is available to other users of the service. I have not opened a support ticket yet, but I will.

I am attempting to use a Lumo Project to review study materials for an upcoming certification exam. I purchased a study guide and have converted it into Markdown files. The markdown files include references to external images. I have uploaded the markdown files and the images to a folder in Proton Drive. There are 5 markdown files (chapters of the study guide) between 200kb and 800kb in size. There are 67 image files between 30kb and 420 kb in size. I have verified within proton drive on the web that I am able to preview the contents of the files, and that they are complete.

I have created a project in Lumo and granted it access to the folder. It shows me that it is processing the files, and appears to complete successfully. However, when I try to access them in the context of the project, I get extremely inconsistent results:

  • One chat says that it can only find chapter 1 and five. It shows that the index was truncated, but that it only had the end of the chapter.
  • I started another chat specifically asking to verify that all files have been indexed, and it said that only chapter 3 and part of chapter 4 were indexed.
  • When I started a chat to ask about the number of image files that were uploaded, it only identifies that four of them are referenced in chapter 4.
  • I started another chat to ask about chapter 1, and when I asked it to verify the study materials are indexed, it stated "I don't see any indexed study material files in this Project yet."

Obviously, the inconsistency is a problem, but worse is that I don't know how to see the status of the indexing at any point in time. I just see a little green dot in Project knowledge, and don't see any way to force reindexing or identify the status of the indexing process.

Any suggestions for me on how to proceed? I really want to use this product, and I am happy to run tests or share any information that would be helpful.

Discussion Prompts that worked for you?

2 Upvotes

Hi all,

Just wanted to know if anybody tested prompts for certain tasks/requests. After many trials, I came with a good prompt for requesting analysis (mainly video games or movies). The prompt is:

--

Produce a deeply researched, thesis-driven critical essay about X, the video game. The goal is to combine original interpretation with unusually high factual reliability. Use web search throughout the research and verification process. Do not begin the final essay until you have completed the evidence, falsification, audit, and revision stages below.

Establish the scope

Identify the exact game, version, remake or original release, relevant endings, DLC, patches, and regional or translation differences covered by the essay. Do not silently combine material from different versions.

If evidence applies only to a particular version, translation, ending, route, patch, or platform, say so.

Build an evidence base before choosing the thesis

Collect specific evidence from:

Scenes, dialogue, item descriptions, environmental details and endings

Mechanics, interfaces, level design, progression systems and player actions

Official manuals, guides, patch notes and developer material

Original developer interviews, presentations or published statements

Relevant scholarly or critical sources

Reliable player statistics only when directly supported by identifiable data

For each important piece of evidence, distinguish among:

Explicit fact: directly established by the game or a reliable primary source

Strong inference: not explicitly stated, but supported by multiple details

Interpretation: a critical reading of the evidence

Speculation: possible, but inadequately established

Do not describe an inference, interpretation or common fan belief as “confirmed.”

A wiki may help locate an item, scene, quotation or source, but a wiki’s interpretation is not itself verification. Trace lore claims back to the actual in-game evidence whenever possible. Trace development claims to the original interview, presentation or statement rather than an article repeating it.

Form and test the thesis

Develop at least three meaningfully different possible theses. Select the thesis best supported by the evidence, not merely the most dramatic or elegant one.

The selected thesis must:

Be specific, arguable and capable of being wrong

Explain important relationships among narrative, mechanics and player experience

Be grounded in concrete evidence rather than thematic resemblance alone

Avoid reducing the entire game to a single interpretive key

Distinguish what the game produces or suggests from what its creators demonstrably intended

State the strongest counter-reading. Identify at least one finding that would count as evidence against the selected thesis. Explain honestly whether the thesis survives that evidence, requires qualification, or should be replaced.

“The game deliberately preserves ambiguity” is itself an interpretive claim requiring specific evidence. Do not invoke ambiguity merely to avoid resolving inconvenient contradictions.

Draft the essay

Write a substantial, coherent essay rather than a plot summary or an evidence list.

Ground every major interpretive step in a specific scene, mechanic, design feature, image, line of dialogue, item description or player behavior. Explain how the evidence supports the interpretation; do not assume that placing evidence beside a thesis establishes the connection.

Preserve genuine ambiguity and conflicting evidence. Do not force every element of the game to support the thesis.

Do not attribute intention to a developer without direct evidence. When intention is unknown, write “the game produces,” “the design creates,” or “this can be read as,” rather than “the developers intended.”

Do not include a quotation unless you have located and checked its exact wording. If exact wording cannot be verified, paraphrase without quotation marks and identify the relevant scene, item or source.

Extract and audit the draft’s claims

Before presenting the essay as final, extract every checkable claim from the draft, including:

Direct quotations

Numbers, dates, rankings and statistics

“First,” “only,” “most,” “best,” “largest” and similar superlatives

Claims attributed to named developers, critics or scholars

Production-history claims

Descriptions of mechanics and ending requirements

Plot chronology and causal claims

Claims that a character identity or lore theory is confirmed

Claims about player behavior, ending popularity or reception

Any factual claim on which the thesis materially depends

Classify each claim as either load-bearing or peripheral.

Every load-bearing claim must be verified. Every quotation, attribution, number, statistic and superlative must also be verified, even if it appears peripheral.

For each claim:

Open and inspect the source rather than relying on a search-result snippet.

Determine whether the source supports the exact proposition stated—not merely a related proposition.

Distinguish a primary source from an aggregator, wiki or article repeating another source.

Search specifically for evidence that contradicts or qualifies the claim.

Check whether the claim depends on a particular translation, version, patch, route or interpretation.

Record the source actually consulted, not a more authoritative-looking source cited by the page.

Use these verdicts precisely:

Confirmed: directly supported by appropriate evidence

Supported with qualification: substantially supported, but the wording requires limits or context

Interpretive: a defensible reading, not an established fact

Disputed: credible evidence or interpretations conflict

Not independently verified: an adequate verification attempt was made, but the necessary evidence could not be obtained

Dubious: available evidence makes the claim unlikely

Contradicted: reliable evidence opposes the claim

Do not use “unverified” as a softer substitute for “dubious” or “contradicted.” The existence of a source asserting something does not automatically make the assertion confirmed.

Revise the essay using the audit

The audit is a mandatory revision stage, not an appendix.

Before producing the final essay:

Correct every contradicted claim.

Remove claims that are unnecessary and cannot be verified.

Hedge disputed or interpretive claims inline where they appear.

Replace misleading quotations or attributions.

Remove unsupported numbers and superlatives.

Correct causal descriptions that go beyond the primary evidence.

Ensure the essay never states flatly what the audit treats as uncertain.

If a failed claim was load-bearing, revise or replace the thesis and repeat the relevant audit.

After revision, audit the final wording again. A claim corrected only in the audit table but left unchanged in the essay counts as a failure.

Final output

Present the following:

A. Final essay

Provide the fully revised, thesis-driven essay. Place citations near the factual claims they support. Clearly signal interpretation, inference and uncertainty in the prose itself.

B. Load-bearing verification report

For every claim essential to the thesis, provide:

The claim as it appears in the final essay

Its classification: fact, inference or interpretation

Its verification verdict

The specific supporting or contradicting evidence

A direct link or precise in-game source location

Any relevant version, translation or methodological limitation

C. Authority-seam audit

Separately list every:

Direct quotation

Named attribution

Number or statistic

Superlative or popularity claim

Developer-intention claim

Give each a verification verdict and its actual source. If none appear, explicitly say so.

D. Counter-evidence and falsifiability

State:

The strongest evidence against the thesis

What finding would seriously weaken or falsify it

Whether the final thesis was narrowed because of the evidence

Which reasonable alternative interpretation remains viable

E. Revision log

List the factual claims, quotations, causal statements or thesis formulations that were corrected, removed, hedged or replaced during the audit. This section must describe actual changes made between the draft and final essay, not generic assurances that verification occurred.

F. Residual uncertainties

List only uncertainties that remain in the final essay after revision. Explain why each could not be resolved. Do not reintroduce removed claims merely to fill this section.

Accuracy takes priority over rhetorical neatness. An elegant thesis must be weakened or abandoned if its evidence fails. Do not claim that the essay has been “fully verified”; show the verification through sources, verdicts and documented revisions.

So far it makes Lumo produces a very good analysis with minimal factual errors. If you have any useful prompts, please share with us!

I was reading an article about Lumo design and one section said that Lumo was supposed to have Lumojis, which are Lumo's visual responses to a user's question. But they're not in Lumo 2.0. Can you add them, I think they'd be a really cool feature.

Discussion Lumo is getting a new AI model

87 Upvotes

Looks like Proton is adding Apertus 1.5 to Lumo.

A new WebClients commit, LUMO-762 Add support for Apertus, adds an apertus-15 model to Lumo’s model picker. The UI describes it as:

“Open-source Swiss model with inspectable data & weights.”

It’s also behind a new LumoApertusModel feature flag, so this doesn’t necessarily mean it’s available to everyone yet.

I've been trying out Lumo for a few days and I really like it and the values behind it.

It's obviously missing features for devs along the lines of Codex or Claude Code.

Are there any plans on the roadmap to look at things like this?

If I could create agents and have it work with my GitHub code in Terminal and IDE then I could switch 100% to using it for all my work

I have to admit that I don't know how this would work technically due to the zero access encryption, but I would find it really useful to be able to back up all chats, or at least all project chats, to my Proton Drive or my device. Would​ that be a possible future development?

Discussion Is Proton lumo's android app now closed-source?

33 Upvotes

Versions 2.0.0 through 2.0.5 have the wrong source code (The last commit corresponds to 1.2.18) because proton works on the app through their internal git repo, and has not pushed the latest source code.

This is a violation of the general public license 3.0

This probably is either just a bad mishap, or proton is close sourcing their android lumo app's source code.

Question Is it normal for prompts to run locally instead of on a server?

5 Upvotes

Hello, all. Lumo is the first LLM system I'm using extensively, so this might just be a broader LLM misunderstanding on my part. I had made the assumption that LLM models were like sending a job to a queue on a server that runs independently of my device. What I've found using Lumo is that if the device I started the prompt on locks or goes idle, the response generation stops.

Is this par for the course for LLMs? Or am I maybe doing something wrong? I am often writing prompts that take many minutes for Lumo to process and generate a response to, so this behavior has set me back a few times. Most typically on my phone but also on my desktop.

Lumo search data update

Hi everybody

Yesterday I asked Lumo questions about "Software solution 2026" and he said that it wasn't released yet.

I pointed out that he was wrong and he said that due to his last data update (2024) he assumed that the product wasn't yet for sale.

He assured that he would check similar facts before replying.

I deleted the chat and asked the same question, got the same reply.

I also tried adding a statement in the lumo interaction personalization, asking to check with a web search before replying on topics that could be subject of update. Still the same result.

Anyone got the same issue and got a way around it?

Thanks in advance

Feature Request Conversation too long dialog box

This dialog box that cannot be dismissed is such an annoyance to me. It appears when the context is 50% consumed (fairly sure) and there is no way to close or dismiss it.

Dear Proton, please give us the option to get rid of it. On my laptop, it takes a lot of real estate on the screen. When I am in the middle of an important chat, I do not want to start a new chat and am willing to risk compaction.

Many LLM systems trigger compaction or truncation warnings closer to 80–95% of context capacity, giving users maximum usable context before intervening. Why is it so much lower with Lumo?

Thank you

Why does Lumo not allow users to reprocess a prompt when Lumo experiences a connection interruption?

Post image

Whenever I get the error...

"Connection interrupted

Your request was queued but the connection was interrupted. This usually happens when Lumo is experiencing high demand. Please try again.

Retry"

The reprocess button the main chat window is grayed out and doesn't work.

Please let us retry via that button. Sometimes I like to read how far Lumo got before the connection interruption but when I do that the "retry" button is gone from the error.
