Datasette Agent ships conversational SQL interface

Extensible AI assistant for Datasette that converts natural language to SQLite queries and charts via plugin system; runs on Gemini 3.1 Flash-Lite or local models like gemma-4-26b.

May 22, 2026

Summary

Eliminates manual SQL writing for data exploration workflows. Plugin architecture lets you inject domain-specific tools (image generation, code execution, charting) without forking core—critical for teams building on Datasette infrastructure.

Why it matters

Implementation verdict

Replaces manual SQL + charting workflows for Datasette users. Requires Datasette instance + Claude/OpenAI/local LLM with reliable tool calling. Ready now for exploration; production viability depends on query reliability against your schema. Start with the live demo at agent.datasette.io to validate behavior.
