What it does
TamedTable is an AI ETL and data preparation tool: load tabular data, describe what you want, and watch it transform. No formulas, no code. Source-available, runs on your own API key.
Load tabular data, say what you want, and watch it happen. AI ETL : no formulas, no code. No API key? Take a guided tour : it replays real sessions, free. The AI understands context, so it cleans, enriches, classifies, and validates: things no formula can. See changes as they happen. Nothing is hidden: TamedTable is source-available , and runs on your own API keys. Every change saves as steps you replay on new data, or export as a Python script. Runs in browser and CLI. Open CSV, JSONL, Parquet, and Arrow files: local, from a URL, or a bundled sample. Preview for cents, run for real when you're sure. AI steps fill the page you are looking at; the rest waits until you ask. Fix messy fields…from tamedtable.com

DTL is a project that began it's life as part of a another piece of software for a startup I founded a few years ago. For that project I needed a way to describe how to rewrite data in a portable way. I needed to be able to create the rules on the fly and store them in a database, I needed them to be able to describe transformations I hadn't thought about, but also needed them to be safe and predictable. Though the startup didn't survive, the language I made was so useful to me I felt I had to extract it and make it usable to everyone. DTL is the result. Though the npm module is relatively…

Clipto MCP▲655Hey 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. We ingest video, audio, image; normalize formats via ffmpeg; run content analysis to…

Hello HN! I found that picking out plausible but diverse skin tones for my digital art and game development projects was kind of difficult, and I got curious about if there was a way to define a color space that made it easy. 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…
