23Editor — Demo video

23Editor — Your Footage. Your Story. 23Editor is an AI-powered Android video editing assistant built to make video creation easier for content creators, educators, small businesses, and social media users. Traditional video editing can require technical skills, expensive software, and significant time. 23Editor simplifies this process by allowing users to describe their editing needs using Tamil or English text and voice instructions. The application uses Meta Muse Spark to generate structured editing plans, Muse Voice Transcribe to understand spoken instructions, and FFmpeg to process and render videos. It also integrates SAM 3.1 for optional subject tracking, Muse Image for requested image assets, and an optional Muse Wonder planning retry. Built with Flutter and a Python backend, 23Editor supports an AI-assisted workflow for video trimming, captions, titles, zoom effects, and video rendering. Our goal is to make professional-looking video editing more accessible to everyone, regardless of their editing experience.
