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…

Hi HN, wanted to share a project that I’ve been working on recently. PodText allows users to find anything said on a podcast. You can also listen and share clips to a specific part of the podcast audio, simply by highlighting the text of that part. Currently there are just over 25k podcast episodes and I’m adding a lot more in the coming weeks (yes my GPU bill is painful).

Unravel▲117You talk, and it automatically builds a visual network of your beliefs, thoughts, desires, and more. The system extracts concepts like beliefs, emotions, and cognitive distortions, then updates a force-directed graph showing how everything connects. Recurring nodes naturally drift toward the center as the graph expands, revealing your core themes. It isn’t intended for therapeutic use. It’s a tool that makes you introspect and helps uncover the driving factors behind your issues instead of trying to solve the problem and suggest solutions (although you can ask it for solutions when needed).…
