Setup & Sign-In
A few quick steps stand between you and your first automation.
1. Choose how to start
When Atom opens, you can:
- Start trial — begins a local 7-day trial (no account required)
- I have an account — sign in to use a purchased licence
2. (If needed) Sign in with email
- Open Atom and choose I have an account.
- Enter your email address.
- Paste the six-digit code sent to your inbox.
You’ll stay signed in between sessions. If you see a seat-limit message, remove Atom from another machine via Settings → Deactivate device and try again.
3. Choose your AI provider
Atom supports Codex, Claude Code, and OpenCode. Choose the provider that matches the account and models you want to use.
OpenAI
- Click Sign in with OpenAI in Atom.
- Finish the browser sign-in.
- Return to Atom and start chatting.
You do not need to install a separate command-line tool. If Codex is already configured on your computer, Atom can reuse that setup too. See Team & Enterprise AI Setup for work accounts, enterprise policy, and API-key notes.
AI usage and limits come directly from OpenAI.
OpenCode
Choose OpenCode in the model selector and follow Atom’s setup card. On macOS, install OpenCode and connect a provider in Terminal, then return to Atom and click Check again. OpenCode models and billing come from the provider you configure.
Atom does not proxy or resell AI usage. You pay the provider you use directly.
4. (Optional) Add integrations
If you want to use hosted media tools, add the matching key in Settings → Integrations.
- Use OpenRouter for image generation.
- Use Pexels to search and import stock images or video.
- Use ElevenLabs for voice transcription with word timestamps.
All three are optional. Leave any service you do not use empty.
