It represents a huge milestone for his ecosystem, opening the door for users to naturally interrogate their databases and easily build custom tools using a new plugin architecture.</p> <h2 id="posts">Posts<a class="anchor" href="#posts">#</a></h2> <p><strong><a href="https://simonwillison.net/2026/May/21/datasette-agent/#atom-everything">Datasette Agent</a></strong> Simon officially announced Datasette Agent, a conversational AI interface that lets users ask questions of the data stored in Datasette. The post features a live demo using Gemini 3.1 Flash-Lite to successfully query a blog database to find a bird-watching record. He highlights a growing plugin ecosystem—including charts, image generation, and sandbox execution—and notes that tools like Claude Code and OpenAI Codex are proving excellent at writing these extensions. Looking ahead, Simon teased a major refactor for his LLM library, a Claude Artifacts-style plugin, and a personal AI assistant named &ldquo;Claw&rdquo; built using his older Dogsheep tools.</p>
