Products that do what My Digital Zettelkasten That Connects Data Engineering and Much More does
I'm sharing my public Second Brain - a digital Zettelkasten that connects my knowledge across Data Engineering, Personal Knowledge Management, Programming, Productivity, and philosophical topics like Digital Minimalism. Built with Obsidian and published using Quartz/GoHugo, this knowledge vault contains interconnected notes that I've crafted, curated, and connected over years. I've developed a streamlined publishing workflow where I simply add #publish to any note I want to make public, then run make deploy through a custom Rust script that's 30x faster than my original Python…

This was more of a sandbox to play with Raphael and Flot than anything else but I think there are some interesting statistics in there. It'd be awesome to do this over time but I really don't have the spare time required.

Everything that would be here is in the README. I hope this gets big, it has tons of potential.

Hi HN, I have been working on a new tool that was inspired by Vannevar Bush's memex and Luhmann's Zettelkasten. Having been a long time user of different tools, I got to the point where I decided to build my own. For the longest time I have been looking for something that puts association first, works as fast as the mind, and allows you to stay in flow state. Making building a second mind, playful and rewarding. If anyone is interested, I have added the link below. At this point I am slowly letting on the first users, and hoping to gather as much feedback as possible. The explore link on the…

Over the past three months, I’ve been working with my dad on this app as a way to learn Cursor, shadcn/ui, and Next.js. I’m currently studying UX design at the University of Michigan, and I’ve been really impressed by how much vibe-coding tools have advanced over the last six months. This work journal includes private AI-generated insights with scheduled summaries that can be shared with your team or manager. You can also choose to make a summary public—like I’ve done here for my work on this web app: https://www.workjourney.ai/summary/mkblt2zt-hn2kdbus If anyone has…

Hi HN, wanted to translate this into a more human-readable post - please see below and would love any and all feedback! What is it: A second brain you self-host and engine to compound itself and spark new ideas, from your own ideas. Why: ROI on your own knowledge, actually realize the value from your ideas. Down the line I'd love for this to evolve into a wider / shareable concept -- Haven't fully figured this out yet which is part of the reason I am posting. View the /constellation folder for the specs on that concept. (Self hosting engine is all in the repo as well) Looking…

Hey HN This project took almost two years and is probably one the best alternatives for tools like Miro and MindMeister Let me know what you think

Try it at: ssh krnl.duetbrowser.com No sign up, totally free - no download. Let me know what you think. Prior art exists (brow.sh) but I wasn't satisfied with their graphical take. I wanted the raw, old skool terminal days of the early internet - BBS, and old green phosphor library comptuers - but running the modern web, with all the bells and jingle jangle whistles (JavaScript, etc). No funding, no VC, just 100% raw terminal fun. Not sure how long the demo will last, but try it out.

The first ever AI peer reviewed research article just got approved. It’s kinda crazy how advanced AI have come to replace researchers. I've just been using Deep Research on ChatGPT and Perplexity a lot to write and research complex technical reports for my boss. He loves the reports and it has decreased my workload a ton but I still have some frustrations with it. None of them provide an API that gets me the same quality of output you would with the applications. I wanted something with more control on the LLMs, swappable with the reasoning new models that came out. Not just prompt →…

Napkinbook is a smart canvas for collaboration, sharing, and discovering insights. I think of it as a more computational version of Excalidraw or Miro: a flexible canvas where you can think, build, present, and collaborate without constantly moving between different tools. Since my first Show HN, I’ve added: * Much better mobile support * AI-assisted brainstorming * Presentation decks with animations * Shareable reports * Live collaboration * Actual Git history The goal is to make the canvas itself the workspace, rather than treating whiteboarding, presenting, reporting, and version history…

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…

From inception Thursday night to near-feature-complete on Sunday morning, I consider it one of my better weekend hacking projects. http://leftright.me/ I built it with node and Redis which was particularly fun. Redis truly is the AK-47 of databases. This project has deeply engrained my longtime hate of Internet Explorer. Everything should be kosher in Chrome and FF but I had to make some compromises for IE. I sent the link to a few friends and the userbase grew from there. It's not much but it's definitely something for having it live for a day. I'm really looking forward to any constructive…

Hi HN, I'm the creator of epress. After a lot of work, I'm excited (and a bit nervous) to finally share it with you. For years, I've been feeling like a digital tenant on the platforms I use every day. My content, my social graph, my online identity—they were all stored on someone else's servers, subject to their rules, algorithms, and business models. I could be de-platformed, my data could be sold, or an API I relied on could suddenly be put behind a paywall. I looked into existing decentralized alternatives. While many are great projects, I found they often shifted the trust from a big…

I was struggling to understand neuroscience and the word associations between technical terms and where the locations are (anatomically) And quite some of my neuroscience friends are loving it.

Hey HN! I develop browser extensions, I suck at web design, and I've been exploring AI/LLMs. With my new found free-time since dropping work hours, I've developed a Design Copilot browser extension [0]. It does what it says on the tin - you choose a part of your website and the tool gives you instant expert design feedback - "change this font to that, add this much whitespace, use brighter colours .... etc" The tool is completely 100% free to use, its powered by bringing your own AI API Key, and the current LLM it uses is Google Gemini 1.5 Pro. I've yet to hit the free rate-limit and I…

Hey there, While searching for my next role as a PM in Blockchain + AI, I started building an AI-powered notetaker called MindNote: https://www.mindnote.online. The idea is simple: you input your thoughts, and AI helps you complete or modify them. If you decide to test it, try using the prompt: Keep this text and…"(add budget, complete list, organize alphabetically, add their translation, etc.). The first big release is all about modifying your notes with AI prompts. The next big step? Capturing thoughts directly from the mind using brain-to-text technology. There is a 3 days free…

App summary: Local-first productivity tool that combines note-taking, task tracking and journaling into one simple app. Advantages over Notion: Way simpler UI, all user data is only stored locally on their device - providing significantly faster load time, fully functional offline mode and complete privacy of their data Advantages over Obsidian: Dedicated features for task tracking and journaling - not just note-taking, with cheaper end-to-end encrypted device syncing compared to Obsidian Sync

Think of HackerNews, but only for AI content. Did build this out of the wish for easier discoverability of new technologies in the AI/ML space. Obviously, so far only a tiny small community, but maybe a few of you find it nice to be around and want to post a link there every now and then :)
