Narrated explainer videos generated from typed topics with animated scenes

It's live 🎉 Type a topic and Storycast makes a narrated explainer video, like the ones you watch on YouTube. Opus 5.5 writes and edits, H3 Max animates. What I love most is how Opus 5.5 writes. The stories have real warmth, the facts are right, and every scene flows into the next one. It never feels like slop. I ran around 250 generations and spent about $1.8K to get the pipeline right, so you don't have to. It's all open source. website: https://t.co/tQovqUqhFt repo: https://t.co/OrSlkcpIpq
