What Reelstuber is
Reelstuber turns one long video into short 9:16 reels for Instagram Reels, TikTok and YouTube Shorts. It listens for the loud moments, spots pauses and scene changes, picks the best 15 to 90 second clips, reframes them, adds animated word-by-word captions and exports MP4 files.
Everything happens in the browser: the video is never uploaded. The server only keeps the edits, so guests can use the whole studio and sign up later to keep projects in an account.
