Make simple software tools with Claude artifacts

Since the Opus 4.1 release, Claude is much better at creating simple software tools. They run as "artifacts" in the chat window, and are easy to share with your colleagues. No coding skills required.

Some example tools, and the chat threads that made them:

• Split long text into chunks (chat thread)

• Write captions for images (chat thread)

• Many more here.

To share the artifacts you make, just click "Copy > Publish artifact" at the top right.

The Claude artifact sandbox has some cool features (e.g. persistent storage; make Claude API calls; MCP integration) but also some major limitations (e.g. restrictions on external web requests). If you're blocked by the limits, try Replit.¹

ChatGPT has a similar feature, called Canvas. It's worse at user interface design and lacks all the "cool features" I mentioned above. But, it does allow external web requests. That would be great, except you can't whitelist a domain—you have to approve every unique URL.
