Before you get started

Before you begin using Breeze tools, make sure to fully understand what steps should be taken ahead of time, as well as the limitations of the feature and potential consequences of using it.

Please note: Please avoid sharing any sensitive information in your enabled data inputs for AI features, including your prompts. Admins can configure generative AI features in account management settings. For information on how HubSpot AI uses your data to provide trustworthy AI, with you in control of your data, you can refer to our HubSpot AI Trust FAQs.

Please note: Breeze features use artificial intelligence and machine learning models. To understand HubSpot’s approach to AI, data usage, and security, learn more about HubSpot's AI Model Cards and HubSpot's AI Cloud Infrastructure FAQs.
