cd ViralCutterEvery project documents its own setup; start with install requirements.
cat README.md | head -60Follow the project’s launch command — Docker, pip, npm, or a binary release.
# see README for the exact launch commandThe code is open source and free. Local AI features cost nothing beyond your hardware; anything cloud-based needs your own API key.
GPL-3.0 licensed — free to use, but distributed modified versions must stay open source.
A GPU makes transcription and generation much faster, but lighter pipelines can run on CPU with smaller models — check the README for requirements.
Exports are standard vertical MP4s, ready for TikTok, Instagram Reels, and YouTube Shorts.
You own the pipeline: no per-clip credits, no watermark, and your footage never has to leave your machine.
