Cardboard is an agentic video editor for the browser and Mac, aimed at people who want to make videos without editing experience. Users describe an edit with a prompt, their footage, or both, and Cardboard builds an editable first cut that can be refined through chat or on the timeline. It cuts dead air, filler words and retakes, pulls highlights from long recordings, reframes for vertical formats, adds captions, generates video, music and motion graphics, clones voices and sources B-roll from the web. Claude Code, Codex and other agents can drive it via CLI or MCP server. Paid plans start at $10 per month, with launch pricing on every plan.
