Northwind Cloud, demo project

Read onlyShare

Build a support agent that answers billing questions from our help center and escalates when it is not sure.

First build, v1. Preview is now on v14.

Built in 6m 31s for $1.46, inside the $1.20 to $2.00 estimate.

Northwind Helpline is ready. 7 conversations are waiting on a human, and 18 are still open.

Code

Every change the agents made, grouped by the request that caused it.

In the full product this opens an editor. This demo is read-only.

42 files, read only. 11 of them open here. The rest are listed so the tree is the real one, not a sample.
