Looks great! I've always felt that tabs and pages don't really fit how I work with information. A node-like approach is much better, and that's what I really liked about Obsidian for keeping and using my personal knowledge. The way you're doing it for learning seems super helpful. Good luck!

Congrats with the launch @kent_no. What are the main use cases for this? Does it have a b2b infrastructure behind?

Something I am fascinated by and don't recall ever seeing before in any type of knowledge or productivity app.

When I collected this longevity research on Eureka at two different points during the research, Notion actually captured the link to the specific point in that research. So each link that I have goes to the same session of research, but at a different points on the timeline within that research.

I don't know if this is by design, but please don't lose this feature; it's actually quite interesting. The idea that I could do research but take snapshots or record checkpoints along that research and then share those links in a curated fashion where the holder of the link is only seeing the research that I've done to that point. Wow! 🧠💣🤯

Again, I don't think I've ever seen that before. It's like WaybackMachine for research! Brilliant!

"We think in connections, associations, and visual patterns." Felt like you have been following me around for the past five decades. This feels so obvious and intuitive and yet it seems to confound people. The push back against deviating from linear processes and conventions throughout my career has been incredibly tacit and indelible. I am seeing a wave of Eureka-like apps and strategies creeping into the light and (what feels like suddenly) being embraced.

I believe the advent of AI is the spark that was missing in previous attempts at connective branching of thought in a digital format. There have been incredible predecessors that could have been catalysts or carved a path, but the conventions were too dense to breach with the tech that was available.

I'm sure there are hundreds of examples , but I believe GoogleWave was one of the earliest pioneers of knowledge connection in a digital world. Then there were adventurers like IQTELL, tree.io, Kifi, DropTask (Ayoa), Zenkit, TheBrain, or NodeLand. More recent canvas tools like Milanote, Weje, or RealtimeBoard (Miro) or relational notes tools like Roam Research, Logseq, or Relanote playing off of the idea of connectedness and associative PKM.

What you are doing with Eureka feels like the level up at a time when not only the technology is ready, but also the audience. I love the rabbithole nature of the exploration or maybe it is more like spores. I'm not sure if this is an ADHD brain's greatest ally or worst enemy, but it is incredibly interesting either way.

Eureka is reminiscent of another tool that launched on PH last week, MyLens, in so much that there is a strong element of visualization and node architecture. I really hope we see a massive proliferation of these types of tools. I think there's so many of us that are visual learners or relational thinkers, and these types of tools are very exciting!

From a practical/UX standpoint, I wonder if there are (I may have missed them) ways to move individual cards around like in a mind-mapping tool and also if there is a way to collapse cards. I struggle with distraction and all of the cards being fixed and expanded can feel overwhelming quickly. I had the same issue with Milanote and Weje when those tools originally launched but they later added both features.

Amazing, everything i need in just a click, one tiny issue is it is taking about a minute to give the result, everything else is fantastic

Always nice to have a full picture of the knowledge to learn - Eureka nails it!

Impressive launch, Eureka team. From a clarity & onboarding lens: when a new user opens Eureka for the first time, what’s the one belief you want them to hold in the first 10-15 seconds?
Is it:
• “I can visualize and explore my knowledge instead of scrolling through pages.”
Or:
• “This tool already understands how I think and what I want to learn.”
Because in knowledge tools the biggest adoption barrier isn’t features; it’s the user believing this will change how I learn. Curious how you’re setting that up.

Hi Kent, Eureka sounds amazing! I can already see how this could massively boost my productivity.

1/ 🧵 Why did I build Eureka?

Traditional knowledge is linear. Books, articles, search results—all force you to read page by page. But our brains don't work that way. We think in connections, associations, and visual patterns.

2/ Eureka transforms any knowledge source into a visual, explorable map:

• Upload a PDF → Get a knowledge graph

• Enter a topic → Explore connections

• Paste a URL → See concepts visualized (on the roadmap)

3/ What makes it special?

• AI guides your exploration (no need to know what to ask)

• Interactive tools on the canvas (calculators, animations)

• Knowledge graph = content script (generate articles/videos instantly)

4/ Perfect for:

📚 Educators creating teaching materials

💼 Professionals learning new domains

✍️ Content creators seeking structure

🧠 Anyone building a knowledge base

5/ Try Eureka today and what topic would you explore first?

Hey Kent, this really resonates why is knowledge always linear is such a good question. Was there a specific book or article where you hit that wall hard?
