An AI video editor with a real timeline

The gap in every AI video workflow is the same. You write a prompt, you get four seconds of footage, and then you open a different application to make it into something you can publish. The clip has no captions, no music, no brand colour, and no second shot. That handoff is where the time goes, and it is where the brand drifts, because the tool doing the finishing knows nothing about the tool that did the generating. Putting a multi-track timeline in the same product removes the handoff. The clip you generated is already on the timeline, your product images are already in the panel, and the export lands back in the same library.

The editor is also reachable by an AI agent, which is unusual enough to be worth stating plainly. Through the DesignerBox MCP server, an agent in Claude, Cursor or your own stack can author a complete video project: clips across multiple lanes, transitions, timed text with animations, audio layers, graphic elements and a colour look. What it returns is not a rendered file but a real project, which you then open in the editor and refine by hand before rendering. Authoring costs nothing; the render is charged once when it succeeds. The same applies to the design editor, where an agent can build a multi-page canvas you finish yourself.

On price, the honest comparison is not a design tool plus a video editor. It is a design tool, plus a video editor, plus a stock music subscription, plus whatever you pay for image and video generation, plus the time spent moving files between them with no shared brand or library. DesignerBox bundles those into one subscription with one credit balance. If you need a template library in the hundreds of thousands, or frame-accurate broadcast finishing, keep the specialist tool for that job. What changes here is that the generate, edit and ship loop stops crossing three logins.
