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…

Hi HN, Since 2019, I’ve been working on a writing platform designed for creating complex documents (e.g., theses). I personally use it for everything as it also allows to classify documents in categories so you can organize them efficiently. As of a few months ago, the app is also available in the browser, and you can now invite coworkers to collaborate on a document in real time. The app is somewhat inspired by LyX. It offers an intuitive, modern editor, but users don’t need to know any LaTeX. When it’s time to export, they can choose from a range of templates (IEEE paper, thesis, etc.). A…

So I've been working on this app for a very long time now. Started off by wanting an app that separates long form notes from short form notes visually and keeps everything organized on a canvas. The app features: -Sticky notes for quick, small notes and A4 notes for long form documents -A quick mode that uses local storage to quickly open the app and jot down a thought on the canvas -A PDF export option that exports your notes into 3 custom designed PDF styles -Visual hierarchy to replicate file structure instead of a linear fashion, where your files are notes, stacks are folders and labels…

It's dead simple. There's no fancy interface. Basic features are gone. That's all on purpose. If you're like me, you're always writing down ideas on pieces of paper. My webapp is like that, but for the internet. Let me know if you find it useful.

Edit: Thank you so much for taking a look at Seen! Yes, I know, it's really slow. And scrolling does not render notes instantly. And the title is a bit clickbait-y. I'll try my best to improve on it though. This is just a preview, the most basic version of Seen, and it's getting there. But, oh God, I almost got a heart attack when I opened up Vercel Analytics and saw ~1,500 page views, up from 10 or 12. Thank you again! It's such a weird experience showing something to the world for the first time as a 16-year-old and seeing so many people look at it. Hello HN! I've been working on creating…
