Profile & Preferences

You can manage your profile, appearance, model defaults, and account from Settings.

Getting to settings

On the web, click Settings at the bottom of the left sidebar. On mobile, tap the Settings tab in the bottom navigation bar.

Profile

• Username — Your unique handle (3–30 characters, lowercase). This also determines your Nebula email address: username@nebula.me.
• Timezone — Set your local timezone. This affects when scheduled automations fire.

Appearance

Choose a theme for the Nebula interface. Themes are filterable by Dark or Light, and each one shows a color preview so you can see what it looks like before selecting.

Default model

Set the default AI model for all your agents from the Models tab. Agents without a pinned model will use this one. You can also choose defaults for media tools and review browser use pricing.

See Models for details.

Credits

Settings shows your Account Balance and Nebula Model Credits. Account Balance can be spent anywhere. Nebula Model Credits are used for the Nebula LLM model, the recommended default for balancing cost and performance.

See Credits for details.

Account

• Sign out — Sign out of your current device.
• Delete account — Permanently delete your account and all associated data, including integrations, files, channels, conversations, tasks, triggers, and encrypted secrets.
