When to choose:
  • You need a free, open-source, cross-platform (macOS/Win/Linux/Android) video editor with zero watermarks or subscription paywalls as an alternative to CapCut.
  • You want local offline AI features (Whisper auto-captions, voice clone TTS, background matting) or want AI agents to automate timeline editing via JSON-RPC/MCP.
When to skip:
  • You need Hollywood-grade colour grading (like DaVinci Resolve) or complex cinematic visual effects compositing (like After Effects).
  • You prefer a cloud app with thousands of pre-made trending templates, stickers, and licensed pop music ready out of the box.
