Datasette Agent: An Extensible AI Assistant for Datasette

Original: Datasette Agent

Simon Willison launched Datasette Agent, an extensible AI assistant that lets users query and visualize Datasette databases using natural language.

Simon Willison announced the first release of Datasette Agent, merging his 'llm' Python library with Datasette. The tool provides a conversational interface to query SQLite databases, with plugin support for generating charts and running code in sandboxes. It runs efficiently on lightweight models like Gemini 3.1 Flash-Lite and supports local open-weight models via LM Studio.

Simon Willison, the founder of the open-source data tool Datasette, has announced the first version of Datasette Agent. This is a milestone product that, for the first time in his more than three years of developing the `llm` Python library, deeply integrates it with Datasette, aiming to provide a powerful and extensible AI assistant for structured data.
