Cardboard is an agentic video editor that runs entirely in your browser. Instead of manually cutting and arranging clips, you describe what you want—e.g., "Cut a 60s brand film from the VO and the site b roll"—and Cardboard watches your footage, finds the best moments, assembles a rough cut, and offers refinements like a 30s cutdown for LinkedIn. It can also reframe videos for different aspect ratios (vertical, square, landscape) while keeping the important action in frame, find specific moments across hours of footage using natural language queries (e.g., "the moment we hugged"), and generate animated captions in multiple cinematic styles. Additional features include translation and dubbing, audio cleanup, volume leveling, color grading, background music, and export presets for various platforms.
