Hey everyone! Solo dev from Germany here. I built CastNova because I kept seeing the same problem: podcasters and YouTubers spend hours after every episode manually writing social posts, newsletters, and blog drafts. That's time they could spend making more content. So I built a tool that does it for you. Upload your episode (audio file or YouTube URL), and CastNova generates ready-to-publish content for Twitter, LinkedIn, Instagram, newsletters, and your blog, in your voice, not generic AI slop. What makes it different: CastNova learns your writing style after a few episodes. The more you use it, the more it sounds like you. It's live at castnova.app. Free tier available (2 episodes/month, no credit card needed). I'd love honest feedback, what works, what's missing, what would make this actually useful for your workflow. I built this to solve a real problem, not to ship another AI tool nobody asked for.
