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…

Hey HN! I love finding new books to read on here. I wanted to gather the most mentioned books and recreate the serendipity of physical browsing. I scraped 20k comments from HN threads related to reading, extracted the references and opinions using GPT-4o mini, and visualised their embeddings as a map. - OpenAI's embeddings were processed using UMAP and HDBSCAN. A direct 2D projection from the text embeddings didn't yield visually interesting results. Instead, HDBSCAN is first applied on a high-dimensional projection. Those clusters tend to correspond to different genres. The genre…

ProductMap AI▲160Hey HN, I built ProductMap AI, a tool that automatically identifies features implemented in source code and organizes them in a visual hierarchy. The goal is to help developers quickly understand poorly documented codebases. Link: https://product-map.ai/ I’d love feedback from the HN community! Let me know what you think. Would this be useful for you?

I've created Tree of Knowledge (tree-of-knowledge.org), a dynamic visualization tool that organizes all fields of knowledge into an interactive tree structure (generated by AI). As a Computer Science student, I built this to make exploring and connecting different areas of knowledge more intuitive and engaging. You can satiate your curiosity and grasp anything a click away... fast and easy. Key features: - Start from the green 'Knowledge' node to explore the entire tree - Customize your own Start Node to focus on any specific area (this can be anything!) - Interactive interface for easy…

Heuristica▲34Hi HN! I have built an AI-based content creation tool called Content Explorer. Instead of writing to create the best content, it allows you to iteratively discover it by offering a bunch of operators that modify and enhance your initial input. The node-based interface allows you to easily visualize the result of your operations and compare and contrast different versions. I like the mental model of Large Language Models as word calculators. So I have built this word editor that works like an image editor since we can now process language just like we have been processing images. You can use…
