Profile & Preferences
Manage your Nebula profile, choose a theme, set a default AI model, and control your account and security settings from the Settings page.
You can manage your profile, appearance, and default AI model from the General tab in 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. Agents without a pinned model will use this one. You can browse verified and experimental models, and each one shows capability badges (thinking, vision, caching) and pricing info.
To override the default for a specific agent, pin a model from that agent's detail page. See Choosing a Model.
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.
Cloud Computer
Explore your Nebula Device's full computing environment — persistent filesystem, code execution, browser control, and live server hosting for your agents.
Usage
Monitor your Nebula credit consumption, request counts, and cost breakdown across AI models and tools from the Usage tab in Settings.
