Everything I built with Claude Artifacts this week

Over the past week, Simon Willison used Claude's Artifacts feature to create 14 interactive web applications, including a URL-to-Markdown converter, SQLite demo, and QR code decoder. Most projects took less than five minutes to build, with the most complex taking 21 minutes. Willison praises Artifacts for rapid prototyping and exploring new technologies, despite limitations like inability to make API calls or link to external pages. He considers it one of his favorite LLM-based tools for quickly generating functional web apps.
