Ask a Human for Help When the AI Doesn't Know the Answer

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](https://docs.n8n.io/advanced-ai/examples/human-fallback/) 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.
