  ChartGen AIJan 2026 · chartgen.ai · ▲489

  Hi HN, I’m the maker of ChartGen AI. Last year, we launched a text-based AI agent called Ada.im. After analyzing thousands of user interactions, we stumbled upon a pattern we hadn't expected: users were constantly trying to paste data rows and ask for visual representations, but the text-based model couldn't handle it well. We realized that for marketers, seeing the trend is more valuable than reading about it. We pivoted that insight into a standalone tool: Drag & Drop: Upload raw CSVs (FB Ads, GA4, TikTok, etc.). Processing: We map the disparate column names into a unified schema. Viz: It…

  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. We ingest video, audio, image; normalize formats via ffmpeg; run content analysis to…

  Simple algorithm and color space to generate diverse skin tones▲627

  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…
