Cardboard

Cardboard is an advanced video editor designed for growth and marketing teams, as well as serious creators who require consistent video production. It eliminates the need for agencies, lengthy timelines, and endless review cycles by allowing teams to provide footage and a goal (such as “3 variants,” “30s hook,” “testimonials”) to quickly receive a strong initial cut for further iteration. Utilizing multimodal LLMs for reasoning over footage and leveraging WebGPU/WebCodecs, Cardboard offers a professional-grade non-linear editor (NLE) directly in the browser. This innovative approach introduces an “AI director” within a professional editing environment. Cardboard tackles the dual challenge of developing a high-performance browser-based editor and an agentic editor reliable for production use cases. Unlike many startups that focus on a single aspect, Cardboard integrates both, offering a comprehensive solution that established companies struggle to replicate without overhauling their existing systems. As video becomes the primary distribution channel, the ability to iterate quickly is crucial for capturing attention. Cardboard positions itself as the default workspace for video production, akin to how Canva and Figma have become essential tools for design, by providing a collaborative, efficient platform that automates tedious tasks.
