ComfyUI-Documents Description

ComfyUI-Documents is an extension for ComfyUI that enhances workflows by enabling advanced document processing. It supports loading, parsing, and converting various document types (PDF, TXT, DOC, DOCX), extracting text, and converting PDF pages to images, integrating seamlessly with ComfyUI projects.

ComfyUI-Documents Introduction

ComfyUI-Documents is a powerful extension for the ComfyUI application, designed to enhance your workflow with advanced document processing capabilities. This extension seamlessly integrates document handling, parsing, and conversion features directly into your ComfyUI projects. Whether you are working with PDFs, text files, or Microsoft Word documents, ComfyUI-Documents provides the tools you need to efficiently manage and process your documents. This extension is particularly useful for AI artists who need to extract and manipulate text and images from various document formats, making it easier to incorporate these elements into their creative projects.

How ComfyUI-Documents Works

ComfyUI-Documents works by adding custom nodes to your ComfyUI workflow, each designed to handle specific document processing tasks. Think of these nodes as building blocks that you can connect together to create a customized document processing pipeline. For example, you can use one node to load a document, another to convert PDF pages to images, and yet another to split text into manageable chunks. By connecting these nodes in different ways, you can create a workflow that meets your specific needs.

Imagine you have a PDF document with multiple pages, and you want to extract images from specific pages and then process those images further. You can use the "PDF to Image" node to convert the pages to images, the "PDF Page Splitter" node to select the pages you are interested in, and the "Image Selector" node to pick the specific images you want to work with. This modular approach makes it easy to customize your workflow and achieve the desired results.
