With the release of OpenAI [Structured Outputs](https://openai.com/index/introducing-structured-outputs-in-t...) it gave me an idea to build a library to make it easier to build Ai powered with functions.

It's somewhat inspired by the many cool libraries in Python. [Fructose](https://github.com/bananaml/fructose), [Ask Marvin](https://www.askmarvin.ai) and others but has a few main differences

* For Typescript!

* Chain AI functions easily and get type safety throughout the entire chain

* Call typescript functions with natural language (or structured inputs). If you define an input schema for your function, it will map the natural language input to that input schema

* Specify output schema for a function. When you call a typescript function you can specify the output schema. (I guess sort of like graphql but for functions?)

Not sure that makes much sense, but I have some examples on the repo!

I'd love to hear your thoughts, feedback, and any creative ways you could use cigs in your own projects. Let’s discuss in the comments!
