OpenShorts

Paste a YouTube link or upload a podcast, webinar, stream or interview, and the AI picks the 3 to 15 moments worth posting. Each one gets reframed to 9:16 around the speakers, captioned, and given a hook. It's built for creators, podcasters, social media managers and agencies who repurpose long-form video. A tool like OpusClip does similar work, but this one is open source under the MIT license.

• Moment detection: Gemini reads the word-level transcript and scene cuts, then scores each clip out of 100 and writes titles and descriptions.
• Smart cropping: MediaPipe face tracking with a YOLOv8 fallback keeps people centered in vertical frames.
• Subtitles: faster-whisper produces word-level captions, burned into the clip in a choice of styles.
• Hooks and effects: AI-written hook text for the first seconds, plus generated FFmpeg filters for color and transitions.
• Dubbing: With your own ElevenLabs key, clips can be dubbed into 30+ languages in the original speaker's voice.
• Publishing: Post to TikTok, Instagram Reels and YouTube Shorts from the dashboard.
• Agent access: An MCP server, API and command line let Claude, ChatGPT or n8n run the same pipeline.

It also includes a YouTube toolkit for thumbnails, titles and descriptions, and an AI UGC generator with lip-synced actors from $0.65 per video.

You can use the hosted version, which includes a free plan and paid plans from $12 a month. Or self-host it with Docker, so videos stay on your own machine. Self-hosters supply their own Gemini key, which has a free tier.
