What is SupoClip?
Open-source AI clipper: long videos into viral shorts
SupoClip is an open-source AI video clipper that turns long videos into viral shorts. Paste a YouTube link or upload a file and the AI transcribes the content, finds the strongest 15–60 second moments, and scores each clip for virality across hook, engagement, value and shareability. Clips are reframed to 9:16 with face-centered cropping, burned-in word-synced captions and AI-generated titles, ready to export to TikTok, Reels and YouTube Shorts with one-click presets — no watermark. Self-hosting is free forever under the AGPL-3.0 license; hosted plans with monthly generation quotas start at $10/month. Available as a web app, iPhone app, REST API and MCP server.
