Your history stays on your PC.

  This is just a small thing I coded to help me see my entire convo history in beautiful markdown, in Obsidian (my note-taking app). [Link to Github repo](https://github.com/mohamed-chs/chatgpt-history-export-to-md). The Python script helps you to convert conversations extracted from ChatGPT (ZIP export all your data, sent by Openai) into neatly formatted Markdown files. Also adds YAML metadata headers and includes Code interpreter (Advanced data analysis) intput / output code. Feel free to fork the repo and implement your own improvements, I feel like there's alot…

  Clipto MCP▲655

  Hey HN, We recently built Clipto. It’s a tool that lets you search over terabytes of video, audio, and images on your computer, without relying on the cloud. Motivation: we probably all had this similar experience, we know a moment exists in a video or audio, but finding it takes hours scrubbing the timeline. You can send all the media to process in the cloud, but it’s slow, expensive and raises privacy concerns. So we decided to build our own on-device media search engine. How it works (high level): 1.

I've built a color picker and procedural generation algorithm based on the space as well as a bunch of other fun js features and demos throughout the page that use the equations. If you find it interesting, I have lots of explanations of how I built it and what properties the space has. The methodology might be a bit shaky, but hopefully the result is as helpful for…
