How to copy text from McGraw Hill Connect

McGraw-Hill’s Copy Prevention

Copying text from McGraw-Hill’s online accounting textbooks has long been prohibited, creating difficulties for students, including myself. Not only does this prevent offline reading, but it hampers studying and taking digital notes on practice problems as well.

While disabling website copy blocking through changing browser settings dom.event.clipboardevents.enabled to true was thought to be one workaround, McGraw-Hill employs JavaScript to achieve their copy protection. Fortunately, I have finally found a solution that does not require circumventing their copy prevention.

Introducing NormCap

I discovered NordCap, an OCR-powered screenshot tool, entirely by accident while browsing the featured category in the Gnome software store on my Linux system (Vanilla OS). Curious, I installed it to try it out.

NordCap allows users to copy text from a wide range of sources, not just images. It enables extracting text from online resources like McGraw Hill Connect as well as videos, photos, GIFs, and essentially any content displayed on the screen.

Instead of capturing images, NordCap is able to detect and extract the text. As shown in the GIF below.

NormCap Demonstration GIF

Step-By-Step Guide

  1. You will need to download and install NormCap via https://dynobo.github.io/normcap/
  2. Start NormCap, a pink border will appear after the permissions have been given by the user
  3. Select the region of text you wish to copy, the text is now copied
  4. Paste the text anywhere or press Ctrl+V to paste from clipboard
  5. Done!

Note: Settings can be accessed by starting NormCap or pressing Capture in the tray icon while NormCap is running, Settings will be located in the top right of the screen as of v0.4.1

NormCap Usage

NormCap provides a free and open source tool for students to capture notes and problem sets. Once NormCap is installed and configured, it enables students to easily copy down assignments and materials to review and study. NormCap offers this functionality without any ads, allowing students to focus on their coursework.

ChatGPT vs. Turnitin – Does the Turnitin Plagiarism Checker Detect ChatGPT?

What Is ChatGPT?

“ChatGPT is a large language model trained by OpenAI that can generate human-like text based on a given prompt. It can be used for a variety of natural language processing tasks, such as language translation, text summarization, and question answering.” – This response was generated by ChatGPT

What Is Turnitin?

Turnitin is a web-based plagiarism detection service that helps educators and students identify potential plagiarism in written work. It compares submitted papers to a database of academic content, as well as content on the internet, in order to identify any matching or similar text. This tool is commonly used by educators to check student papers for plagiarism, as well as by students to check their own work for potential issues before submitting it.

Does the Turnitin Plagiarism Checker Detect ChatGPT?

Short Answer: No, here’s why.

ChatGPT is a language model that is based on a machine learning algorithm. It learns from every response it generates, constantly fine-tuning itself to produce more human-like text. Imagine a classroom of 100 college students who are all taught the same information. If you were to ask them all the same question, they would all give different answers. ChatGPT works similarly, as it is fed with millions of data points, allowing it to come up with unique responses. However, traditional plagiarism detection software such as Turnitin will not be able to detect plagiarism from ChatGPT, as it can change its responses in a way that is not easily traceable. Additionally, even newer programs specifically designed to detect ChatGPT plagiarism, like GPTZero, will not be able to keep up with the vast amount of data these models are trained on. Ultimately, the company with the most data will have an advantage in this field, as seen with companies like Google, Facebook, Apple, and Tesla.

Data/Results

I have conducted an experiment where I used ChatGPT to generate 20 essays, and then submitted them to Turnitin for plagiarism detection. The results showed that all the essays received a passing score, with very low similarity to other sources. This suggests that using ChatGPT to generate essays will be able to bypass plagiarism detection software such as Turnitin, as the model’s ability to produce unique responses makes it difficult to detect plagiarism.
