No, Notion AI requires Notion. Notion AI works inside the Notion workspace and draws on its content, so it is not a standalone assistant. ChatGPT does not require any particular workspace.
Notion does not train on customer data by default, and owners can opt in. ChatGPT consumer conversations may be used to improve models unless you turn it off or use temporary chat; Business, Enterprise, Edu and API data are not used for training by default.
ChatGPT plans never include API usage; the OpenAI API is billed separately. Notion plans include the Notion REST API, which is a workspace API and not an LLM endpoint.
