SupoClip

SupoClip is an open-source tool for converting long-form videos into vertical clips optimized for YouTube Shorts, TikTok, and Instagram Reels. It uses AI to detect highlight moments, score them for virality, and automatically crop and caption them with face-aware framing. The project describes itself as an open-source alternative to OpusClip, offering self-hosting, no watermarks, and full source code access alongside a hosted web and iOS app option.

The tool includes AI-powered segment detection, word-synced subtitles, virality scoring across hook, engagement, value, and shareability, face-centered cropping via MediaPipe, B-roll overlays from stock footage, and one-click export presets for major platforms. It's built with Claude and available as a self-hosted Docker setup, hosted SaaS, iOS app, REST API, or MCP server for use in Claude and other AI tools.
