ChalkTalk: Globalizing Data Science Education with AI-generated Videos
summary
Open-source ChalkTalk converts Quarto documents into multilingual videos by adding simple TTS and TTV attributes to markdown, integrates with Quarto and publishes code on GitHub, and is already used by The GRAPH Courses which trained over 3,000 learners. Prototype is built in about four weeks via vibe coding using an open QAN480B model for text and ElevenLabs TTS for voice; slide generation works, full avatars, SVG support and security hardening remain unfinished and A/B testing is preliminary.
