ViralWiz is a commercial SaaS tool that uses AI to automatically detect viral moments in video footage, reframe to 9:16 with speaker tracking, generate word-by-word karaoke captions, and auto-publish to social platforms. It targets content creators looking to streamline short-form video production. The project is not open-source (no repo, license, or code available), and the README is minimal marketing copy, limiting evaluation as an open-source project.

Target audience: content creators, social media managers, video editors
