How to Create Your Own Custom GPT from Any Website with GPT Crawler

Distinct from other AI models, Generative Pre-trained Transformers, or GPTs, are adept in creating human-like texts for varied subjects and fields. Yet, their levels of proficiency and knowledge may differ, based on their data and parameters. To optimize this, a custom GPT can prove extremely beneficial – understanding and answering site-specific questions with absolute precision. In this comprehensive article, we delve into the open-source project, GPT Crawler, and how with just a URL, you can convert any site into your unique GPT.

Understanding Custom GPTs

Custom GPTs, a revolution in digital communication and automation, are akin to tailored AI chatbots that are specifically designed to meet the unique requirements of websites and applications. Not just simple utilities, these GPT models are transformative gateways to personalised user experiences. What sets these custom GPTs apart is their adaptability, enabling their integration into diverse platforms where they provide bespoke responses, guidance, and even coding support, tailored to their specific training. This user-centric customization enhances user experience by addressing individual user queries directly.

What is GPT Crawler?

GPT Crawler is an open-source solution which allows you to crawl a website and generate a knowledge file. This can be used to create a custom GPT from a URL. The crawler can be configured to suit specific requirements, such as initiating a crawl from a certain URL, matching patterns, and selecting the inner text to capture.

Key Features Description
Customization The facility of URL specification makes it possible to crawl any wanted site, hence collecting content specifically tailored to the needs.
Depth of Knowledge Meticulous data collection from designated pages leads to a comprehensive repository of knowledge.
Flexibility Adept at handling diverse content types, including public and client-side rendered information.
User-Friendly Configuration Easy setting adjustments within the ‘config.ts’ file enable customizing URL targets, pattern matching, and page limitations.
Efficiency Thanks to the use of a headless browser, the crawler operates efficiently, effectively capturing dynamic web concepts and enhancing overall performance.

Guide to Using GPT Crawler for Creating a Custom GPT

Before a custom GPT is created from a site, it requires the site’s text data that acts as the knowledge base for the GPT. This data is extracted using a web crawler – a program that automatically browses and extracts data from the web. GPT Crawler is such a web crawler that is planned to crawl a site and create a JSON file containing the title, URL, and text of each page. This file can be uploaded to ChatGPT – the platform where custom GPTs can be created and shared without any need for coding.

Cloning the Repository and Installing the Dependencies

Getting started with the GPT Crawler requires cloning its repository. For fetching the necessary files onto your system, run the following command in your terminal:

git clone

This will create a local copy of the project on your system. Now, the dependencies of this project need to be installed. These dependencies are essentially the software packages necessary for the smooth functioning of the project. Use the npm install command in your terminal to install these packages, which are listed in the project’s package.js file.

Configuring the Crawler using the Site URL and other Parameters

Post-cloning, open the config.ts file and input your custom configuration. This file houses the parameters which guide the behavior of the crawler. The url parameter is the most critical; it signifies the inception of the crawl. Feed in the URL of the site that needs to be crawled to generate a custom GPT.

Running the Crawler to Generate the Output file

Configuring the crawler enables launching the crawler through the npm start command in the terminal. The ensuing crawl begins at the specified URL. Dynamic site content is effectively captured by the crawler due to the use of a headless browser. Crawling non-public information, i.e., logging into a website, can also be customised. As the crawl progresses, key details such as title, URL, and text of each page are printed. Post completion of the crawl, the output file, mentioned in the config file, saves all the output.

Integrating and Using the Custom GPT

With the output.json file ready from the GPT Crawler, you can directly upload it to ChatGPT. This involves the creation of a new GPT and its configuration with your file, effectively empowering it with the knowledge collected from the crawled pages. A straightforward procedure enables interaction with your custom GPT using the user-friendly interface. This tool is extremely beneficial for those wanting to quickly deploy a custom GPT for common use or testing purposes. However, for a more comprehensive solution particularly in product development, the OpenAI API offers robust support. The API grants access to your custom GPT, enabling smooth embedding into your products or services. This method is ideal for delivering customised assistance within your digital offerings, ensuring alignment with the specific knowledge relevant to your product or content.
