A browser-based toolkit for trimming and downloading clips from YouTube, TikTok, and Twitch, solving the need to extract specific segments, convert to MP4/MP3, and reformat to vertical 9:16 without watermarks or re-encoding quality loss. It sells to individual consumers and creators who repurpose podcasts, streams, and social videos for personal use or short-form content.
