## About

YepCode lets you build custom AI tools using your own code with JSON Schema-defined inputs, executed in an isolated sandbox with access to any npm or PyPI package and secure environment variables.

Define reusable processes in Node.js or Python, expose them as callable AI tools, and execute them on demand or on a schedule. Every run is logged and auditable, enabling traceable, production-grade AI integrations.

Built for developers who need programmable, observable AI tool execution.

## How to use

1. **Add it in ChatGPT** Open YepCode in ChatGPT's Plugin directory (button above), select + to add it and sign in if asked.

2. **Use it in a chat** Type @ in the composer and pick YepCode, or start your message with its name. ChatGPT may also suggest it when it fits what you ask.
