This AI tool allows users to enter their OpenAI API key to authenticate and access the OpenAI API through local API calls. The tool emphasizes that it does not store or share the API key and assures that the service is free-of-charge. However, it reminds users that the OpenAI API itself is not free and encourages them to review the pricing information to avoid any extra costs. The tool does not provide a title or a description beyond these authentication and pricing details. It serves as a simple interface for users to enter their API key and utilize the OpenAI API for their applications. The potential applications of this tool would depend on the capabilities of the OpenAI API that users are accessing.
