Zync: Upload once, publish to 16+ platforms with AI captions

Hey Product Hunt! 👋 I'm Denis, a solo dev from Denmark. I run several small YouTube channels on the side, and reformatting + re-uploading every single video to each platform ate hours of my week. The existing schedulers treat video as an afterthought — so I built Zync. Upload one video, and Zync: generates platform-specific titles, captions and hashtags with AI • auto-reframes to 9:16, 1:1 or 16:9 with face detection (Magic Crop) • publishes to 16+ platforms in one click • tracks everything in one analytics dashboard. Free plan: 3 channels, no credit card. Paid plans from $9/mo. I'd love honest feedback — especially on what's missing for YOUR workflow. I'll be here all day answering questions!
