While developing poincake, I actually thought about building a language learning app using a similar approach. The idea was to map word embeddings onto a Poincaré disk so users could explore word relationships and clusters.

I'm thinking LOD might help mitigate the overlap issue, perhaps by having an LLM progressively shorten the text until it's a single Unicode character.

Also, as other comments suggested, shading or similar techniques could help.

That said, I doubt this can be fully resolved unless the text is rendered in hyperbolic space, as another commenter mentioned. I'll need to experiment and see if that's doable.

(I'm the dev) I tried it out on an iPad and it seems to work fine. Let me know if you run into any issues. Supporting direct stylus/Pencil input will definitely be a challenge, but I think it’s worth a shot.

Show HN: Infinite canvas notes in the non-Euclidean Poincaré disk

Hi!

This is an infinite canvas note-taking tool where notes are laid out in a non-Euclidean, hyperbolic geometric space. As you drag and navigate through the view, you’ll experience a unique fluid distortion that naturally leverages your brain's spatial memory.

I’ve been obsessed with the concept of space in HCI for years. Many modern UI patterns are essentially workarounds for the lack of screen real estate. While researching zoom-based UIs a while back, I stumbled upon old HCI papers that used the Poincaré disk model of the hyperbolic plane to organize data. It elegantly projects an infinite space into a finite disk, keeping everything contextually visible.

I wanted to build an experimental app around this concept years ago, but the non-Euclidean math was a significant roadblock. Recently, I decided to give it a shot with the help of LLMs. It turns out that LLMs can handle the mathematical heavy lifting quite well, specifically in designing the coordinate systems and optimization algorithms, provided that you guide them with a solid architectural design.

This is still an experimental demo, but I hope it leaves an impression. I’d love to know if you find this paradigm practical for organizing your thoughts.

DHH probably just reached for "ressentiment" because it sounds cool. I can't get over how ironic it is to put Nietzsche and democratize in the same post.

At least the recent popularity of the 996 originated in China, and I believe most Chinese people would agree with that. Besides, even if it started in Hong Kong, saying it originated in China is still technically correct.

The Turing test isn't dead. The true Turing test is a thought experiment, and it's not something that can be replicated in the real world.

Given enough time and interaction, you can still spot a person on Discord being faked by an LLM—at the very least, something will feel off. This is even more true in a formal, knowing, adversarial setting.
