Built-in vs Custom Agents
Understand the difference between Nebula's built-in agents and custom agents you create, and learn how to enable, disable, and inspect them.
Nebula comes with powerful built-in agents ready to use from day one. You can also create your own custom agents tailored to specific tasks, apps, or workflows.
Built-in agents
Built-in agents are pre-configured by Nebula and available to all users. You don't need to set anything up — Nebula uses them automatically as needed.
Searches the web, scrapes pages, extracts structured data, and automates browser interactions.
Writes and executes Python, JavaScript, and Bash code on your Device.
Transcribes audio, describes images, generates images, and converts text to speech.
Sends and reads emails from your Nebula inbox at username@nebula.me.
Creates new custom agents based on your description.
Your agents (custom agents)
Custom agents are agents you've created — either directly or automatically when Nebula created one to handle a task. They appear under Your Agents in the Agents section.
When you connect an app via Integrations, Nebula can automatically create a dedicated agent for it.
Enabling and disabling agents
You can enable or disable any agent. Disabled agents won't be used by Nebula when delegating tasks — useful if you want to prevent Nebula from using a particular agent or app connection.
Which agent does Nebula use?
Nebula automatically selects the best agent for each task based on what you've asked. If you want to direct Nebula to use a specific agent, you can mention it by name:
Use my GitHub agent to list open issues.
Found 14 open issues across 3 repositories.
Not sure which agent to use? Just describe what you need — Nebula will pick the right one automatically.
