Atom is ready to use after you sign in with OpenAI. Anthropic is optional and connects through Claude Code.

Install Claude Code

  1. Open Terminal and run:
curl -fsSL claude.ai/install.sh | bash
  1. Run claude.
  2. Follow the browser sign-in prompts with your Anthropic account.

Back in Atom

Restart After Effects, open Atom, and choose Claude Code from the agent menu. If Atom does not pick it up right away, tap Refresh in the setup screen.

Troubleshooting

  • Atom doesn’t detect Claude Code: Restart After Effects and tap Refresh in Atom. Verify Claude Code works by running claude --version in a terminal.
  • Anthropic authentication error: Run claude in your terminal and complete the sign-in flow.
  • Non-standard install path: Make sure the Claude Code binary is on your system PATH so Atom can find it.
