A new take on the workflow.

GnaegiCut provides a layered video timeline, text and image overlays, transitions, local Whisper captions and FFmpeg export for short-form videos. Its README identifies it as a CapCut alternative built with Claude, and its original implementation commit explicitly credits Claude. Downloadable macOS releases are provided.

What you can switch today.

Replace CapCut on macOS for assembling short clips, adding text and captions, arranging audio and exporting a finished short video.

Download the documented macOS release and open a new project.
Import the original video and audio assets, rebuild cuts and add text or local captions.
Export and check a representative short video before recreating further projects.

Switching caveat. Use for the documented basic cut, caption and export workflow; keyframes, speed editing and native CapCut project migration are not established. Workflow evidence

Where it falls short.

macOS only. The README lists keyframes and clip-speed editing as missing. No native CapCut project importer is established; rebuild from original media. The downloadable app and representative exports have not been independently runtime-tested.

Documented capabilities.

Listed in project documentation; not independently functionally tested by VibeAlt.

AI contribution verified. The original code-bearing implementation commit explicitly describes Claude building this CapCut alternative and credits Claude Sonnet 5.5 as coauthor. This establishes attributed original-build involvement rather than proving every line was AI-written. Inspect the evidence
