Team-GPT is a collaborative workspace that allows teams to work together and master ChatGPT. It enables multiple members to collaborate in the same chat, organize chats in folders, and share them with others. The tool provides a user-friendly interface, prompt templates, and the ability to edit and delete messages. It aims to help teams and individuals adopt AI by teaching them how to use it effectively. Team-GPT also offers company billing and invoices, making it more cost-effective than individual ChatGPT subscriptions.
