I never expected my previous post to receive such an enthusiastic response. The amount of feedback and support was genuinely overwhelming, and I’m incredibly grateful to everyone who tried PenEcho and shared their thoughts.

To make PenEcho more useful for learning, collaboration, and creative exploration, we’ve added a new plugin system that allows AI to return richer, interactive, and even animated content directly to the canvas.

How it works

When a plugin is activated, the language model becomes aware that the plugin is available. It can read the API interfaces provided by the plugin, organize the appropriate output, and send structured results back to the canvas. The canvas then renders that content in a suitable visual and interactive form.

Interestingly, we found that even a basic general-purpose plugin can support calculators, clocks, animations, and many other tools you can imagine.

You can also create your own plugins.

For example, you could simply describe what you want:

“I want to retrieve air-quality information based on an address.”

Then click AI Optimize, and the AI will automatically help you design and configure the plugin. You can save it locally and, in the future, publish it to the PenEcho community plugin library, which is currently under development.

I hope people will use this system to create entirely new and imaginative ways of interacting with AI.

Thank you again for all the support.
