AI running coach documented with JavaScript-generated videos

By PulseAugur Editorial · [1 sources] ·

A developer documented their AI running coach product by creating 21 narrated videos, each approximately 35 minutes long, without using traditional video editing software. Instead, they generated each video as a web page where frames are drawn in JavaScript on a canvas based on elapsed time, synchronized with a free synthetic voice-over. The project, named canvas-video-skill, was largely coded using Claude Code and is available as an open-source tool, offering features like multi-language support, diff reviews in pull requests, and pronunciation checking with Whisper. AI
