## What Stack AI is

Stack AI is a platform for IT teams building and operating AI agents across an enterprise. It is intended for organisations with regulated or complex operations that need to deploy, govern and scale agents. It offers a free plan and a custom-priced enterprise plan.

Pricing: It offers a free plan at $0 per month and a custom-priced enterprise plan.
