Open-source AI clipper: long videos into viral shorts
SupoClip turns long videos into vertical, captioned shorts. Paste a YouTube link or upload a file: AI transcribes it, picks the strongest 15–60s moments and scores each for virality, then crops 9:16 around the speaker and burns in word-synced captions and a hook title. Trim, split, merge and export for TikTok, Reels and Shorts. No watermarks. Open source (AGPL-3.0): self-host it free, or use the web app, iPhone app, REST API or MCP server.
SupoClip is an open-source AI tool that converts long videos into vertical, captioned shorts by identifying and scoring key moments for virality. It supports various formats and platforms, allowing users to trim, split, merge, and export content without watermarks.
A source that found nothing is a measurement. A source that has not run is a gap. Neither means the launch lacks the thing.
