How to Find Slack Users with ChatGPT

ChatGPT finds Slack users by name and presents their profile clearly — handle, display name, status, and any available contact information. Useful for building a workspace directory or finding the right person to contact.

Steps
Once connected (see setup above), use the Slack tool:
- Ask: "Find [name] in our Slack workspace"
- ChatGPT returns the user profile with their handle and status
- Ask: "List all users in the workspace" for a full directory view
- Use the returned details to send messages or manage channels
Example Prompt
Try this with ChatGPT using the Slack tool
Find all users in my Slack workspace with "engineer" in their title and list their names and Slack handles.
Tips
- Ask ChatGPT to format user results as a contact directory if you need to share them
- List all workspace users to find the right person when you only know their role, not their name
- Ask whether a user is active or deactivated before sending a message to an old account
