I like it. Much nicer than having to use some python SDK in my opinion. Is this a standalone language or it requires Python or other languages to run it?

Its an interpreted language. The interpreter and parser are written in TypeScript so it does use Javascript at runtime but its not a transpiled language that is just converted to Javascript.

The Convo-Lang CLI allows you to run .convo files directly on the command line or you can embed the language directly into a TypeScript or Javascript applications using the @convo-lang/convo-lang NPM package. You can also use the Convo-Lang VSCode and Cursor extensions to execute prompt directly in your editor.

The Convo-Lang runtime also provides state management for on-going conversations and handles the transport of messages to and from LLM providers. And the @convo-lang/convo-lang-react NPM packages provides a set of UI components for building chat interfaces and generated images.
