AI-native CRM that builds itself and does work for you

Hey Product Hunt! 👋 I built Thinking Line because most AI video tools generate visuals, but don’t actually teach. They create motion, not understanding. I wanted a way to turn a simple prompt into something that feels like a real teacher at a whiteboard step by step notes, structured scenes, synced narration, and visuals that build concepts progressively. What started as an experiment in generating SVG doodles evolved into a full pipeline that writes the lesson, draws the board, narrates it, and stitches it into a cohesive explainer video. To prove it works, I used Thinking Line to create an entire public Mathematics course. You can try the web app or plug directly into the API. Happy to answer anything about how it works under the hood, the pipeline, or where this is going next.
