Introduction

Atom is an autonomous agent for After Effects, powered by Claude Code or Codex running locally on your machine. Ask for the change you want and Atom understands your composition, writes the script, and applies it instantly. There are no panels to configure and no code to tweak.

What Atom Helps You Do

• Clean and organize — Rename, reorganize, and batch edit layers with a single prompt.
• Try ideas in seconds — Sketch motion, timing, and colour variations without touching the graph editor.
• Apply expressions instantly — Ask Atom to add wiggle, link one property to another, or break down what an existing expression does.
• Create useful rigs — Build controllers, connect layers to shared sliders, and keep everything in sync without digging through menus.
• Generate images — Create textures, sprites, and mood frames directly in chat. They’re auto-imported into your project.

What You’ll See

• A clean chat timeline with inline progress updates.
• The Atom Config for switching agents, models, and thinking modes on the fly.
• File attachment support for sharing images, PDFs, audio, documents, and other context.
• Automatic checkpoints that let you restore your After Effects project to any point.
• Skills that save reusable patterns, brand guidelines, and techniques across projects.
• Conversation branching and message editing to explore different approaches.
• History and Settings tucked away until you need them.
