DataLang is a tool that connects to databases and utilizes GPT for real-time conversation. Users can set up data views (e.g., SQL scripts), configure GPT assistants, publish customized GPTs to the ChatGPT store, and share them with users, employees, or customers. DataLang also allows users to automatically convert SQL views into APIs and create custom GPT assistants for database conversation. This product streamlines the data analysis process, requiring only simple database configuration, data view addition, GPT assistant selection, and custom GPT creation for real-time data interaction.
