Cardboard edits the footage you have. Vupie makes the film you don't have yet.

Cardboard is an agentic video editor from Y Combinator's Winter 2026 batch. Give it footage, a prompt or both, and its agent builds an editable first cut: it trims dead air and filler words, adds captions, reframes for social and generates shots and music when you need them. It runs in Chrome, and as a Mac app that edits and exports on your Mac. Vupie starts where there is no footage yet: it writes the script, generates every shot, voices it and renders the finished film on our servers, so there is nothing to install and any device will do.

WHERE CARDBOARD SHINES

Edits your own footage: cuts dead air, filler words and retakes, and finds the best moments in long recordings
Recipes: remix a video you like into your own version
Timelines out to Premiere Pro, Final Cut Pro and DaVinci Resolve
Works with your own agent: Claude Code and Codex in the Mac app, or any agent through its CLI and MCP server

WHERE VUPIE IS DIFFERENT

Nothing to install: the studio runs in the browser on a computer, tablet or phone
Footage, voice and the render run in the cloud, so a slow laptop renders as fast as a new one
Narration timed to the word, with charts and maps from your data
Every number checked against its source; one without a source blocks the render

Side by side.

What each one does for someone who needs a finished film. Cardboard's side is from its public information, checked 25 October 2026.
