Show HN: I Built an AI Explainer Video Generator

I think NotebookLM is really cool, but I wanted something that doesn’t just generate text or audio—I wanted it to create videos. So I built an AI-powered explainer video generator that takes text, file, or topics and turns them into fully formatted videos with narration, subtitles, and animations. How it works: You provide a script or upload your files. The tool adds AI-generated narration, subtitles, and animated visuals. It applies smart cuts, animations, and transitions to make it engaging. Everything runs in the browser, so no need to install anything. My goal is to make explainer video creation as fast and effortless as possible. Would love to hear your thoughts, feedback, or feature ideas! Try it here: [https://www.goact.fun/ https://www.goact.fun/]
