Alternatives to Chegg Plagiarism Checker

Generally speaking, other plagiarism detectors, such as Grammarly and Originality.AI offer a more thorough scan at a lower price point. Although Grammarly and Originality.AI are paid services compared to Chegg’s basic free plagiarism checker, the results are much more thorough and include additional services that students and professionals alike will find helpful.

For example, Grammarly offers suggestions on how to improve writing style and tone, whereas Originality.AI scans for AI-written content in addition to content that may be plagiarized from other sources.  

What is Originality.AI?

Originality.AI is a plagiarism detection platform that goes beyond your average plagiarism checker to include the ability to check for AI-written content with a high degree of probability. Although not specifically designed for academia, Originality.AI nevertheless can help professors detect AI-written content and essays from students, including those written with the latest version of ChatGPT and other AI-writers.

How Does Chegg Compare to Originality.AI?

Chegg claims to search millions of online sources, but it pales in comparison to Originality.AI which spans over 70 billion web pages. What’s more, although Chegg’s user interface is simple and uncluttered, Originality.AI’s color-coded matching system and highlighted text make it easy to spot potential plagiarism or AI-written content at-a-glance.

Because Chegg is oriented toward educators, it works with a number of learning management software like Canvas and Blackboard, whereas Originality.AI is a standalone platform. And last but not least, Chegg is limited to per-document pricing, while Originality.AI offers both a subscription-based plan and a per-document plan, making it much more flexible for those professionals who want to run multiple scans, or who want to choose between scanning for plagiarism, scanning for AI writing or both.

How Does the Originality.AI Algorithm Work?

Originality.AI’s sophisticated algorithm leverages the power of artificial intelligence algorithms to detect the tell-tale signs of content written by AI services like ChatGPT. Through consistent training and machine learning, as AI writing services like this evolve, Originality.AI also evolves to spot potential instances of AI content.

Originality.AI’s algorithm first breaks down the text into smaller chunks, which it then compares to its billions of documents in its database. The algorithm also identifies areas of similarity and through its machine learning ability, looks to determine if a text is actually plagiarism or not. For example, a quote or a common expression would not be flagged as plagiarism from Originality.AI because it is sophisticated enough to know the difference.

Once the scan is complete, which takes just a few minutes, a color-coded report is given to the user that highlights any potential matches on a case-by-case basis, making it easy to correct.

The Bottom Line: Should You Use Chegg’s Plagiarism Checker?

Chegg is a decent albeit very basic plagiarism checker. Overall, when compared to other tools on the market, it sadly lags behind in terms of its database size and price point. If you only need to run a precursory plagiarism check from time to time, Chegg’s tool may be useful, but when compared to more advanced, AI and machine language-powered tools like Originality.AI, Chegg simply doesn’t have the computing power or the intelligence to make a smart guess as to what plagiarism is beyond a direct text match.

Start using Originality.AI now to scan your documents for as low as one cent per 200 words. With flexible per-document or subscription-based pricing and the ability to scan for plagiarism or AI detection, Originality.AI makes it easy to ensure your documents are high quality, human-written, and free of plagiarism.
