NodeLand▲533Hello, HN! Have you ever considered that you might be a visual thinker? A lot of studies emphasize the benefits of visual thinking in learning, as it activates different parts of the brain and enhances comprehension and retention. It is common, for example, to remind yourself of a concept by visualizing the page where you wrote it down. This is because the brain is more likely to remember visual information than text. Unlike traditional linear note-taking apps like Notion and Evernote, NodeLand introduces a revolutionary connection-based model. Everything you write is seamlessly integrated…

I built this tool because I wanted a way to just take a bunch of URLs or domains, and query their content in RAG applications. It takes away the pain of crawling, extracting content, chunking, vectorizing, and updating periodically. I'm curious to see if it can be useful to others. I meant to launch this six months ago but life got in the way...

Lore▲130I built Lore because I kept losing knowledge — curl commands, quick notes from standups, and that one thing I told myself I'd remember. It lives in the system tray, a global shortcut pops it up, you type naturally, and it stores or retrieves automatically. Everything runs locally via Ollama + LanceDB — no cloud, no API keys. It classifies your input (thought, question, todo, instruction) and uses a RAG pipeline to answer recall queries from your own stored context. It's free and open source under MIT license, and even though its in very early version me and my friends have been using it for…

Hey HN! Over the weekend (leaning heavily on Opus 4.5) I wrote Jargon - an AI-managed zettelkasten that reads articles, papers, and YouTube videos, extracts the key ideas, and automatically links related concepts together. Demo video: https://youtu.be/W7ejMqZ6EUQ Repo: https://github.com/schoblaska/jargon You can paste an article, PDF link, or YouTube video to parse, or ask questions directly and it'll find its own content. Sources get summarized, broken into insight cards, and embedded for semantic search. Similar ideas automatically cluster together. Each…

doXmind▲108Hi HN, I’m Steve, co-founder of doXmind. We built doXmind for people who want docs and AI, but not all of Notion. Notion is powerful, but if your main use case is writing, collaboration, and AI help inside documents, it can feel like more than you actually need. You end up inside a much bigger workspace of databases, templates, and project management features, when sometimes all you really want is a clean doc editor with strong AI built in. So we took a different approach. In doXmind, AI works directly in the document instead of living in a sidebar chat. It reads the structure of what you’re…

While summarizing videos (I'm the Eightify founder), I've been secretly working on an AI-generated encyclopedia, and here's why. I found myself thinking a lot about AI and content. Now we have knowledge (think Wikipedia) and intelligence (LLMs). They will both significantly improve soon. What we lack is *a knowledge interface for humans*. What I don't like about current interfaces: - ChatGPT: to get an answer how I want it, I need to craft a perfect prompt - Google: need to spend time avoiding affiliates and unreliable sources - Wiki: great, but boring to read, too much information What I…

Hi HN, I'm a solo developer learning to code, and I'd love to share my second real project: MapMyLearn, an AI-powered app that automatically generates personalized learning paths based on any topic you input. What it does: Takes a topic (e.g. "history of capitalism", "learn Rust", or "data storytelling") Uses AI to break it down into a structured course with modules and submodules Each submodule includes: - Detailed, pedagogical content (developed based on online sources to mitigate hallucinations) - A quiz of 10 questions - Recommended resources - An AI chatbot for Q&A - Optional audio…

ThinkTotem▲12Hi HN, I love reading non-fiction, but I kept catching myself skimming, zoning out, and forgetting most of what I’d “read”. To fix that I built ThinkTotem, a small web app that lets you upload a PDF/EPUB/article/YouTube link and then chat with the material until you actually understand it. What it does - Ingests PDFs, EPUBs, Word docs, plain-text URLs and even YouTube transcripts (≤ 4 MB for now) - Maps key ideas, trims filler and surfaces the essential concepts automatically - Runs an active-recall loop: Socratic questions, explain-it-back prompts, spaced-repetition style…

When I do real research — reading papers, books, or trying to understand a complex topic — it never happens in one sitting. I explore a bit, get interrupted, come back days later, ask new questions, find new sources, and gradually build understanding. Existing AI tools are great at answering questions once, but they reset context every time. Notes tools preserve text, but not understanding — they don’t help me reconnect ideas, revisit sources, or see how my thinking has evolved. I built Kerns to sit in between. Kerns is an AI research workspace designed for research that unfolds over time.…

Auto Mind▲13I’ve always been curious about big, complex topics; things like quantum computing, AI ethics, or philosophy, but I’d often get stuck at the very beginning. I’d open a dozen tabs, skim Wikipedia, and still not feel like I had a good mental model of what I was even looking at. So I built a tool to help with that. You type in any topic, and it generates a simple mind map; just a few high-level subtopics to start. Then, as you click and explore those nodes, it expands outward with more specific, connected concepts. The map grows with your curiosity. It’s intentionally lightweight and…

I haven't seen anything like this so I decided to build it in a weekend. How it works: You see a bunch of things pulled from Wikipedia displayed on cards. You ask yes or no questions to figure out which card is the secret article. The AI model has access to the image and wiki text and it's own knowledge to answer your question. Happy to have my credits burned for the day but I'll probably have to make this paid at some point so enjoy. I found it's not easy to get cheap+fast+good responses but the tech is getting there. Most of the prompts are running through Groq infra or hitting a cache…

Hey everyone! I know that a lot of people want to make more time for reading in their lives, but don't always have the time to do so. So I've created Summrize, an online platform for reading FREE non-fiction book summaries. For each book, I've condensed the most important concepts, quotes, actionable insights, frameworks and case studies, and presented them in a beautiful format. You can save the snippets that resonate the most with you, and share them on other platforms too! We know there exist other similar platforms (Blinkist, Shortform), but my goal with Summrize is to make access to the…
