What It Does
Sandbox is an extension for Premiere Pro and After Effects that lets you generate animations by typing what you want. It connects to AI models including Gemini, OpenAI, and Claude, then uses web-based rendering engines like Three.js, GSAP, p5.js, and Pixi.js to produce editable, render-ready assets directly in your Adobe timeline. The output is code-based, meaning you can go back and modify it with further prompts rather than starting over.
Key Features
Text-to-animation generation. Type a description and Sandbox generates a working animation using industry-standard JS libraries. This covers kinetic typography, 3D models, particle systems, physics simulations, and more.
Free Web Engine. Added in v1.0.1, this generates full HTML/CSS/JS pages inside the panel. You can load CDN libraries, build interactive dashboards, music visualizers, or games with mouse, keyboard, and touch support.
SVG Rigging Mode. For character animation work, you can click on parts of an SVG and assign semantic labels like HEAD, LEFT_ARM, or BODY. Those labels get passed to the AI as context, so prompts like “raise the left arm” produce accurate results.
Data visualization. Upload JSON, CSV, or TXT files and the AI parses them to generate charts, graphs, and data-driven animations without manual setup.
Real-time interaction capture. Record mouse movement live on the canvas and export it as a Null layer with keyframes in After Effects. You can also drive canvas interactions using existing AE layer position data.
Live server control. A live server feature lets you control After Effects using voice in real time by connecting Sandbox to an external server.
Who It’s For
Motion designers who want to prototype animations quickly without writing code. Also useful for editors who need data visualizations, infographic animations, or character rigs without switching to a dedicated tool. The Premiere Pro integration means you can generate assets without leaving your editing session.
Pricing
Sandbox is a one-time purchase at $19. A free trial is available. Single-user licenses cover up to two computers (not used simultaneously). Floating server licenses are available for team environments.
