Alternatives
Products that do what Inspired by the 'memex' I created Kokoro for building your second mind does
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…

Inspired by the following post by photon_off... http://news.ycombinator.com/item?id=1683309 I made karmurl last night. It's a simple app where you submit a URL for feedback, then for every piece of feedback you give to someone else's, you get to read one piece of feedback for yours. http://karmurl.com

Hey Hacker News, I'm the maker of Kopage, a free & self-hosted Website Builder. While working on new, cool features (AI, of course), it would be great to hear some HN feedback :) Thanks, Simon

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…

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…

Hi Everyone, I recently wanted to learn Japanese with duolingo but it kept giving me repetitive lessons. So I built an app that gives a variety of lessons from anime. You can try it out here:https://kanjieight.vercel.app/ Thanks everyone.

Hi HN! Me and my buddy made this in a weekend as an experiment in 1. building something quickly and putting it out there and 2. using AI in an interesting way; in this case a poetry judge. Our “judge” isn’t perfect, but the hope is that at least it’s a relatively fair system that everyone can be sure evaluates their work. Anyway, we wanted to see what the lovely people of HN think of it. Some background on the idea; I like poetry and thought it would be cool if there was a big competition with a large financial incentive that scales with the number of participants. Using AI as a judge allows…

Hi HN, I am a solopreneur in the evenings and a software engineer during the day. In the past, I have created lots of calculators for my web projects and freelancing friends. These were pretty basic, but users always welcomed them. I also used currently available builders, but the problem was that they were either slow, broke on mobile devices, had nonsense page view limits, or were expensive. Some even ticked all those boxes. So I have decided to create my own, with a simple interface, and called it Creative Widgets (if it ever takes off, I plan to add more exciting stuff like charts, etc,…

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, I'm the creator of this project. For the past months, I've been working on building an AI agent that could move beyond simple generation and tackle inventive challenges autonomously. The core idea was to create a system with a "metacognitive loop"—the ability to recognize when it's stuck on a fundamental problem and then launch a sub-mission to solve that specific bottleneck before continuing. The linked article is a deeper introduction to the system's architecture and a snapshot from a recent run. I tried to design it to be evidence-grounded and self-critical to avoid the pitfalls of…

Hi HN, I'm thrilled to share with you think, a command-line tool that I developed while diving back into the programming scene. For the past few years, my focus had shifted from hands-on programming to managerial roles, my last one being at Affirm (I started Affirm's Polish office). However, I recently left my job to revisit my passion for coding and see if I could still write code that works. Not to mention that with what is currently going on in AI if you are a developer this probably the best possible time for a sabbatical in human history :) My first attempt was with LangChain, but I…

I really struggle to keep my notes organised, and often can't make any sense of hand written notes after meetings. I did some experiments with Claude and ChatGPT where I blast random thoughts at them during a meeting or brainstorming session and then have them output a nice document that pulls it all together at the end. It worked incredibly well but it was a bit cumbersome to keep sending messages to the chat and telling the ai each time what to do. So I took the idea and built a tool, it makes it easy to throw random notes and voice recordings (images and document support on the way) and…

Hello! I love anki and have been using it for years to learn mandarin, but I'm lazy and always struggled to get over the "motivation hump" to sit down and create a deck. Recently I've been consuming a lot of AI content from youtube, and spent 3 days creating a deck for Andrej Karpathy's "Deep Dive into LLMs" video. This is impractical - so I built a little youtube to anki converter @ asimpleai.com It's rough around the edges... but I would like it to eventually become something useful to community. Feedback and suggestions are welcome! peace

Hello there! I hope you're doing well today! I wanted to share something with you. Recently I was on the hunt for the best way to journal daily. Well, I had this idea - what if I could feed all my daily entries to an AI (ChatGPT), and create a friendly, supportive character like Socrates or Simon Sinek? This way, I could ask any questions about my life and mental health, and get some amazing advice on how to improve myself! The results have been absolutely mind-blowing ! I even made a short GIF to show you how it works - check it out! - https://gifyu.com/image/SdHLH I've…

After reading gwern’s post two days ago about LLM Daydreaming [0], I wanted to just see how it would behave. I grabbed the top vital article titles from wikipedia [1] and made a simple next js app to try the prompt in a loop. It was pretty interesting to see the connections made between concepts. Happy to host this if people find it useful! [0] https://gwern.net/ai-daydreaming [1] https://en.wikipedia.org/wiki/Wikipedia:Vital_articles

Hi HN, I’m still in college and new to the startup world, but here is my first shot at a side project: Milburn, an integrated therapy+journal tool(https://milburn.vercel.app/). I built Milburn bc every mental health tool I could find was missing something: the therapy apps didn’t have voice/memory/too expensive, and the journal apps were always a PITA to sync with therapy. We trained the chatbot’s model on specific therapy modalities(I personally need CBT sessions, but we also have others like DBT), and then created a prompted journal, added a feedback loop, voice…

Hello everyone, I doubt this would be relevant to the kind of person who uses HN, but I thought I could share for some feedback. I built this site because there is a whole world of people who believe in new age spirituality and I am very much one of them. It is a site where you get the users gender their goals and their images and use AI and psychology to generate images of them in the process of achieving their goals. I am so deeply struggling with how to get this highly on Google. I don't even know if that is important anymore. What are your suggestions with distribution and getting in…

I’ve always liked fast online tools for jotting notes or organizing thoughts — but most “productivity” sites either save data to the cloud, require sign-ups, or are full of distractions. So I built an online productivity tools website, a small collection of browser-based tools. It includes an online notepad where you can write and save notes right in your browser, a cornell notes tool available in more than 20 languages, and more coming soon like a pomodoro timer and a simple blank page for focused writing. Everything works entirely in-browser using localStorage — no accounts, no cloud sync,…

Hey! Just launched my new project. The cmaps platform was created after a long period of research and development in the field of education. It's known that human thinking is not linear, but rather associative. Without realizing it, we are constantly making connections between the things we learn. I believe that the best way to learn is to make these connections explicit. Instead of studying and taking notes in a linear fashion, we should be able to create a map of the concepts we are learning. This way, we can see the big picture and understand how everything is connected. I can say that…

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…
