This is a workflow that tries to answer user queries using the standard GPT-4 model. If it can’t answer, it sends a message to Slack to ask for human help.

It prompts the user to supply an email address.

This workflow is used in Advanced AI examples | Ask a human in the documentation.

To use this workflow:

1. Load it into your n8n instance.
2. Add your credentials as prompted by the notes.
3. Configure the Slack node to use your Slack details, or swap out Slack for a different service.
