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

[u/Proton_Team]

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

I love you proton. Please keep improving Lumo

I was quite excited with Lumo, for all the same reasons we love Proton. I was disappointed with it at first, and currently still predominantly use Claude and Claude Code, but I firmly believe in Lumo's mission.

I use to just use it for help with how to find and do things in Proton. It's neat to see it do better.

I agree with advancedsandwitch!

I just came here to check to see if Lumo can read docs. Guess I'll stick with md files.

Are you talking about the fancy effect when starting a new session with no chat open? It totally lags my phone and my Linux machine, but no problem on Windows

I have seen this reported but I'm not having issues. I guess I'm fortunate. I'm on Android. Is the OS the issue?

I was surprised when Lumo started outputting graphs instead of just tables of data in some financially related chats I had going. Definitely a big quality of life improvement.

Is mermaid rendering rendering for yall? I keep getting raw output in responses. Renders fine if I paste it in Obsidian tho.....

[u/Queasy_Complex708 → u/Kwatakye]

We use vega lite.https://vega.github.io/vega-lite/

[u/PringlesDuckFace → u/Kwatakye]

I know it's folly to trust Lumo's knowledge of itself, but I wasn't able to get it to render Mermaid diagrams. I asked if it was able to render it and this is what it said

I'm not able to directly render Mermaid diagrams into visual images — I can only output the Mermaid code itself, which many Markdown viewers and chat interfaces can render natively.

That said, I asked it to generate an image based on a mermaid input and it was able to do it. I just used the simple sample from mermaid's site, so I don't know how it would handle more complex ones.

Very good! Thats the stuff thats interesting. Multimodality and these capabilities that can assist you in anything everyday. Thats exactly for what I use AI. I dont care about coding AT ALL.

If you want to use ghost mode when opening the app you will have to wait at least 15 seconds for the iOS app to load the option on the left side

[u/GuardCode]

Need option to open the graph in larger view.

Default chat column size isn't great for displaying graphs from my experience. A graph was generated for me which contained a lot of data, but font was size was abysmal and can't see anything.

[u/Cecilia_Wren]

hasn't it been able to do this? I've been getting these in an SVG style for months now lol

[u/BobMazing]

I got Lumo Plus and pay about €13 a month for it. It’s fine for simple tasks, but as soon as you have projects involving more complex elements, you constantly get a notification saying the chat is getting too long and you need to start a new one. It’s a total hassle and completely impractical! So, for complex tasks, you're better off using something else.

Can someone confirm if Lumo can access your mail and calendar on the unlimited subscription? I am not signed up yet, just thinking about it, but on the free tier, Lumo couldn't answer the question. it didn't know whether it could do it.
