Using NI Nigel AI in TestStand
Learn how to install, access, and configure NI Nigel AI in TestStand.
Installing Nigel
Nigel installs by default while installing TestStand. If you do not want to install Nigel, you can deselect NI Nigel AI for TestStand <Version Year> when setting up your TestStand installation.
Accessing Nigel
TestStand integrates Nigel into the TestStand Sequence
Editor, making it easy to open a chat window with Nigel from the toolbar by
selecting the Nigel AI
icon.

After you open Nigel, you must log in to your ni.com user account and ensure it is associated with an active subscription license, multi-seat license, or Software Service Program for TestStand Development System.
Accessing Nigel Chat History
Nigel stores your conversation history so you can start new chats and return to
previous ones at any time. You can access your older Nigel conversations using the
Show chat history
button next to the Create new
chat
button. You can rename, delete, and pin chats in the chat history
to organize your chats and allow easy access to important questions.
Attaching Files to Nigel Conversations
Nigel includes an Add File to Context
button which lets you give Nigel additional context to better answer your
queries.
- Attaching a specifications file you want Nigel to import specifications from.
- Attaching a text file containing detailed instructions for a task you want Nigel to execute.
