Clapper

Clapper is a free and open-source AI video editor built for the era of generative filmmaking. It handles images, videos, sounds, and music on one timeline, and it uses AI to simplify the editing workflow rather than just adding filters. Two features stand out. First, a music assistant plugin that extends music editing beyond basic track placement. Second, voice command control, which lets you drive parts of the editing process by speaking instead of clicking, useful when your hands are busy or you are reviewing footage. Additional video editing plugins extend functionality further, multitasking support helps when several jobs are open, and the interface is described as clean enough for both beginners and professionals.

Open-source editing software often has rough edges. Expect occasional bugs, incomplete documentation, and slower support than a commercial product, and check recent activity before committing a project to it. The site was also returning errors in our checks, so availability is uncertain and worth verifying. Voice control accuracy depends on your microphone, accent, and ambient noise, and it works better for simple commands than for detailed adjustments. Plugin quality varies by contributor, so treat third-party plugins as experimental until you have tested them on a real project.
