# Creating & testing custom scripts

## Introduction

As noted in our custom scripts introduction, you can create scripts in our proprietary script editor, using a range of languages.

If you're experienced in creating scripts for your Patchworks process flows and know exactly how to achieve what's needed, you can jump straight in and [create your script from first principle](/product-documentation/developer-hub/custom-scripting/creating-and-testing-custom-scripts/creating-a-script-manually.md)s. However, if you'd like some help, you can enter requirements and [ask our AI agent for assistance](/product-documentation/developer-hub/custom-scripting/creating-and-testing-custom-scripts/creating-a-script-with-ai.md)!
