Built on the engine behind Captions. Proven by 250 million videos and counting.

Give your agent the engine.
Let it skip the interface.

Strata lets your agent edit projects and render video directly, without opening Premiere or After Effects. The agent can spend its effort on the creative work instead of navigating menus and clicking controls.

Professional video has a language. Now your agent speaks it.

Keyframes, adjustment layers, compositions, timing, and sound are native parts of a Strata project. Your agent works with video directly, instead of translating an edit into HTML or React.

Make the cut, animate the graphics, and shape the audio through one agent working on one connected project. You don’t need to learn a separate application for every discipline.

A closer look at Strata.

What is Strata?

Strata is a creative suite built for AI agents. Its native engine combines video editing, motion graphics, compositing, and sound in one editable project. It runs locally on Apple Silicon Macs.

How can I edit a video with ChatGPT or Claude?

Install the Strata plugin in a supported local agent environment. Give the agent your footage and brief. It uses Strata to build the edit, preview the result, make revisions, and render a video on your Mac.

Can an AI agent create motion graphics with Strata?

Yes. Strata supports full motion-design scenes and overlays on footage, including animated typography, keyframes, easing, compositions, and adjustment layers. Describe the result and refine its timing and design with your agent.

Can I make social ads and product launch videos?

Yes. Bring footage, screen recordings, brand assets, and audio. Direct your agent to combine the edit with graphics and sound, then revise the hook, pacing, or framing for the campaign you are making.

Can I change one part without recreating the whole video?

Yes. Strata keeps the project editable. Your agent can change a title, adjust a keyframe, move a clip, or rebalance audio while keeping the rest of the project in place.

How is Strata different from HTML or React video tools?

Strata uses a native creative project model built around video layers, compositions, timing, and sound. Agents work directly with editing concepts rather than representing the video as a webpage or a React application.

Is Strata free to use?

The local creative engine is free, including local preview and rendering. Your AI agent’s subscription or model usage costs are separate. You do not need an Adobe subscription to use Strata.

What computer and agent setup do I need?

The initial release supports Apple Silicon Macs and compatible local agent environments. Use the ChatGPT or Claude setup guide for installation. A browser-only chat cannot run the local binary on your Mac by itself.

Do I need to know how to code or use After Effects?

You can direct the creative work in plain language through the plugin. Strata gives the agent editing documentation and examples. Developers can also use the binary and documented interfaces directly.

Can I use another agent or build my own video editor?

Yes. The standalone engine has documented interfaces and runnable examples. Connect another agent, or ask it to build manual controls for timing, typography, color, and framing around the same editable project.

Does Strata generate footage or AI avatars?

Strata focuses on editing existing media and creating motion graphics. Bring recorded or generated footage, images, and audio into the project. Footage generation and avatar creation are separate tools.

How is Strata related to Captions?

Mirage makes both products. Strata is the engine and agent product. Captions is the app and cloud workspace, powered by Strata. Local Strata use requires no Mirage account. Captions services are separate from the local plugin release.
