# Human

> The nodes in the Human category of the Add node panel: Quick Form and Action App, which pause a workflow until a human responds.

The **Human** category of the **Add node** panel holds the nodes that ask a human to review, approve, or fill in something. The run pauses at the node, and continues with the human's answer.

- [Quick Form](node-quick-form.md): a human fills in a form that you build on the node, and the workflow continues with their answer.
