AI YouTube Shorts Generator is an open-source alternative to clipping services such as Opus Clip, Vidyo.ai, Klap and SubMagic. You give it a long-form YouTube video and it returns ranked, vertical 9:16 clips suitable for Shorts, Reels and TikTok, without per-clip credits or watermarks.
Under the hood it transcribes the video with Whisper, uses a GPT-class language model to detect the most compelling moments, and crops the footage to a vertical frame automatically. The authors emphasize control over the highlight algorithm, and the repository topics cover auto-clipping, auto-cropping and highlight detection. It is written in Python.
The project is MIT-licensed and runs on your own machine with your own model access, which suits creators, agencies and developers who do not want subscription fees or minute caps. The website is run by a related commercial video tool, so check for a hosted option there.
