Maximize the Potential of ChatGPT on Any Website: A Beginner’s Guide

Have you ever thought about how useful it would be to access ChatGPT on any website you visit? You don’t have to wonder anymore because you can achieve this with UserScripts and a browser extension called TamperMonkey. This guide will walk you through the process of installing TamperMonkey, explain what UserScripts are, and show you how to incorporate ChatGPT into a userscript. Additionally, we’ll showcase some exciting and innovative examples that will enhance your browsing experience and boost productivity. The best part? You can do this on Android, iPhone, Windows, Mac, and Linux!

What are UserScripts?

UserScripts are essentially small scripts or programs written in JavaScript that can change the way a website looks or behaves. They are executed on the client side, which means they run within your browser, without needing to modify the actual website’s code. This makes them a powerful tool for personalizing and optimizing your browsing experience, as you can tailor websites to suit your specific needs and preferences. With UserScripts, you can do things like remove annoying ads, add new features to websites, and automate repetitive tasks, among other things.

How To install TamperMonkey

To install TamperMonkey, follow these steps:

  1. Open your web browser (such as Chrome, Firefox, or Safari).
  2. Go to the TamperMonkey website (
  3. Click on the “Download” button.
  4. Select the version of TamperMonkey that is appropriate for your browser and operating system.
  5. Click on the “Install” button and follow the on-screen instructions to complete the installation process.
  6. Once TamperMonkey is installed, you should see a TamperMonkey icon in your browser’s toolbar.

That’s it! Now that TamperMonkey is installed, you can start using UserScripts to modify websites to your liking.

How To Use ChatGPT with UserScripts

I’ve prepared a simple UserScript example that uses the ChatGPT API to generate a random search query and populate Google’s search bar with it. To use this script, simply:

  1. Get an API key from OpenAI: Sign up for an API key at
  2. Open TamperMonkey dashboard: Click on the TamperMonkey icon in your browser and choose “Dashboard.”
  3. Create a new script: Click on the “+” icon to create a new script.
  4. Copy and paste the example script below and replace ‘YOUR_KEY_HERE’ with your actual API key.
  5. Save the script: Click on the disk icon to save your script.

Now, whenever you visit’s homepage, the script will run, and the search bar will be populated with a random search query generated by ChatGPT.

This certainly isn’t a very fun example, you & ChatGPT can come up with a specific UserScript for any website that actually does something neat!
