LayerProof Chromo - Build slides from your data, every claim backed by proof

Hey Product Hunt! 👋

I'm Nathan, founding member at LayerProof. Some of you might remember us from our Social Content Creator launch a few weeks ago (#5 Product of the Day, still buzzing from that).

Today we're back with LayerProof Chromo, our AI slide maker.

Here's why we built it: We tested 6 AI presentation tools and fact-checked their outputs. The best one scored 44% accuracy. The worst was 17%. That means more than half of the data points in most AI-generated decks are either wrong, made up, or impossible to verify.

If you've ever used an AI slide tool and thought "this looks great but... is any of this real?"

That's the problem we're solving.

LayerProof Chromo works differently:

→ Drop in messy data, notes, or connect Notion to turn ideas and raw information into visualized slides

→ Our AI agent reads your sources, structures a narrative, and builds real visualizations.

→ Every single claim in the deck is cited. Click any data point and trace it back to the source.

Every number, every quote, every claim links back to where it came from, so you can verify it in one click instead of fact-checking the whole deck.

The accuracy research we published has been one of the most-read pieces on our blog. Turns out a lot of people have been burned by AI slides they couldn't trust.

Chromo gives you 1 free month to try it. We'd love for you to try it, break it, and tell us what's missing.

I'll be honest, I want to become a data analyst. I came from technical support, and when my role shifted toward marketing and reporting, the idea of making sense of spreadsheets and turning them into something presentable felt overwhelming. LayerProof changed that.

What impressed me most is how it reads your data and structures the narrative for you. That's the part that used to take me the longest: staring at a table trying to figure out what it means and how to explain it to someone else. The charts it builds are clean and actually usable. Not the kind you screenshot and hope nobody zooms in. With LayerProof, the work is already cited. You can trust what you're presenting, and so can the people you're presenting to.

What used to take me hours of copy-pasting between tabs now takes minutes. For anyone on a lean team wearing multiple hats- this is the kind of tool that makes you look like you have a full analyst on your side.

As a marketer and one of the first users, I’ve been living in LayerProof Chromo for months and tested it everyday. I used it to craft 100+ social posts and, more importantly, to build 10+ decks I presented to the company directors.

When I'm presenting to leadership, "I think this is right" isn't an option. I need proof.

Every time I found a bottleneck or a data quirk, I logged it. And every single day, our engineering team took that feedback and shipped a new release. We did this for weeks until we had a tool that I could finally "stand behind" in a boardroom.

It’s been a grind, but seeing the final version live today is so rewarding. If you have 30 seconds to give us an upvote or a comment, it would mean so much to me and the team. 🚀 🔥

what sources it can generate from? i have bunch of excel files that need analyze & charting 😢
If it supports I will give a it try. btw nice product.

Hey PH, Chan here, founder of LayerProof. A few months ago I was trying out a bunch of AI slide tools. At first they looked great: clean, polished, very “ready to present.” But the more I used them, the more I felt something was off. Everything was very template-driven (gamma, beautiful, magnus, claude, etc..), and while they were good at generating template + text, whenever the idea got even a bit complex, they would just add more text (lolz) instead of actually generating something meaningful and that kind of defeats the whole point of slides.

So we decided to try something different. Instead of starting with templates, we worked backwards: we focus on visuals + data first, like diagrams or images that explain the idea, then build the structure and narrative around that. It turns out this works surprisingly well, especially for more technical topics like math, physics, etc.

We’re still a small team and this is very early, so there’s a lot we want to improve. Please give it a try, break it, and tell us honestly where it doesn’t work yet. It’s free during beta, and I’d genuinely love your feedback. Thanks!

curious, how the citation layer handles data that gets updated over time?
e.g if a stat in the source changes after the deck is built, does it flag that?

I’ve actually felt this pain a lot. Tried a few AI slide tools before and always had that weird feeling like “this looks nice… but can I trust any of it?” — and most of the time, I couldn’t without double-checking everything myself.

The fact that Chromo lets you trace every claim back to the source is honestly what makes this different for me. It removes that mental overhead of constantly second-guessing the output.

The "every claim backed by proof" angle is brilliant — decks full of unverified stats are the bane of boardrooms. For marketing/brand decks: our API returns hard data on AI visibility — share of voice across ChatGPT, Claude, Gemini, with exact citation rates. Imagine a slide that says "ChatGPT recommends us 67% of the time" with a live API source. api.foxapis.com/docs — /v1/geo/share-of-voice. — Saul

This is really cool, guys. Congrats! Does this support team collaboration as welll?

This is the new thing that helps me can visualize the data and knowledge. I spent a bunch of time just for making the traditional slide manually. I tried many other tools but the result is not good. Finally I found this one, it can strongly adapt my requirements with a good context memory. Just providing the content and watch a random YouTube video, you will hahe the good visualization material to present or meeting. That is so cool
