The SingleStore plugin for ChatGPT-4 is now available, allowing users to query their database in English and power modern generative AI applications. To get started, users need to install the plugin by searching for it in the plugins store, activating it after installation, and connecting to a supported database such as SQL or MongoDB. Once connected, users can execute queries, analyze database structures, create Notebooks, and view their contents. The plugin also provides additional functionalities like database structure analysis and execution of aggregate queries. Users can access more resources and tools by visiting the SingleStore blog and registering for upcoming webinars on building ChatGPT apps and data strategies.
