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…

Hey HN! I’m Simone. We re-built Breadboard, a visual app builder that mixes Figma-style UI design with Shortcuts-style logic so you can build, preview, and publish interactive web apps directly from the canvas. What it does Design UIs visually with a flexible canvas –like Figma–. Define app logic with a visual, instruction-stacked editor inspired by Shortcuts. Live preview apps directly on the canvas –no separate preview window–. Publish working web apps with one click. Why we made it Modernize the HyperCard idea: combine layout, behavior, and instant sharing in one place. Reduce friction…

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…

Hey Everyone, been working on a note-taking app called janta (Just Another Note Taking App) the past few months. You can try it out at app.janta.dev (you will be redirected to app.janta.dev/canvas/temporary, which is the locally-stored whiteboard you can access) I felt limited with OneNote, Excalidraw, and other infinite-canvas style apps, so I built an alternative. You have access to code-editors, Desmos graphs, and rich text editors (SlateJS). This is because the canvas is designed in a way that allows web components to exist on the same layer as pen-strokes, so you can annotate…

Hey HN, I’m excited to introduce Dashboarrrd, a project I’ve been working on that aims to give you the flexibility to create your ideal workspace. Inspired by tools like Notion, Figma, and FigJam, Dashboarrrd allows you to design customizable dashboards—or “Spaces”—where you can organize, manage, and collaborate on your projects. Unlike Notion, which is text-based, Dashboarrrd provides a blank canvas that you can fill with various widgets. These widgets range from Kanban boards and to-do lists to embedded content and file management tools. The idea is to give you the power to build a…

I got the idea of [mindmap.so](http://mindmap.so/) out of my own frustration of managing my personal notes in Notion and Miro in parallel. I have built it 3 months back on top of excalidraw, posted it in Reddit a couple of times, and never looked back (was using it only for personal use). Little did I know that the small and nimble tool that I created has crossed 2000+ users (was so surprised when I saw the dashboard last week). It was all organic and word of mouth . Having 2000+ users trusting a product is no easy feat. That’s when I thought may be I should put some more…

I am a software engineer working alone on a passion project, a website that helps you stay organized easily and efficiently. Headspace.io is a webmail, notepad, task list and calendar, all rolled into on. The basic premise is that any data in Headspace can be "tagged" and then all relevant information for a particular tag can be displayed in one screen. This is a pre-beta build and I'm hoping to get some early feedback from the wise and generous HN folks. Would you pay a small monthly fee ($5 maybe) for a service like this? http://app.headspace.io/ (This is pre-production so…
