SupoClip

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.
