Your account has been deleted. Thank you for training with us. Describe a reference image in your own words → an AI draws what you said → you're scored on how close it got. A training game that sharpens how precisely you put things into words — and how well you prompt any AI. You don't need to memorize prompts. You need to see — with your own eyes — what your words actually produce. Kotoba Dojo turns that into a game. AI courses hand out "magic prompts." They work once, then your situation changes. The prompt was never the problem — you were vague, so the answer was too. This isn't prompt engineering. It's knowing what you want, precisely enough that an AI can act on it.

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…
