About

AI Shorts Generator is an open-source, self-hostable short-drama pipeline. Long to 9:16 shorts via LLM highlight detection, Whisper and auto vertical crop.

Our take — AI Shorts Generator for short drama

AI Shorts Generator attacks a different problem: instead of generating footage, it mines long videos for viral moments — Whisper transcription, an LLM virality framework scoring hooks and emotional peaks, then auto-crop to 9:16. Our read for short drama operators: this is the repurposing tool — feeding it full episodes or live streams to farm clip-teasers is exactly the workflow short-drama distribution runs on.

Setup is light by open-source standards — MIT license, Python 3.10+, ffmpeg, and a choice between an API mode and a local mode using faster-whisper with an OpenAI or Gemini key. At 4.1k stars it is a smaller project than MoneyPrinterTurbo, and the README itself flags that Whisper struggles without clear speech, which matters for dialogue-heavy drama audio with music beds. Test on your noisiest episode first.

Watch out

README notes Whisper struggles without clear speech — dialogue over heavy music beds may transcribe poorly.
