Open-source AI clipping tools (2026)
These tools cut long videos into vertical shorts on your own computer, with no credits or watermarks. In return you need Python and FFmpeg (ideally an NVIDIA GPU), and most call an LLM API such as Gemini or OpenAI to pick the moments. SupoClip also sells a hosted version from $10/mo. OpusClip and Klap AI are listed as hosted options if you'd rather not set anything up. We found 5 tools that match. 4 have a free option.
