Review: PCMag

Fast and accurate grammar and spell check. Excellent interfaces across platforms. Premium tools considerably improve writing.

Expensive. Limited free version. Lacks support for Google Docs or Office on Mac. No offline mode.

Bottom Line
The real-time grammar and spell check, Grammarly, provides an excellent set of writing and editing tools across a wide range of platforms, but its high price limits its appeal.

Pros: It is super easy to use. You just copy/paste an article into the textbox, hit the button “Premium Search” and it will instantly tell you if your content is original or not.

I have had hundreds of freelance workers producing content for me over the years. More than half of them have tried to submit content with huge sections they blatantly stole from other websites. So having this tool, has saved me a lot of hassle and money.

Cons: It is a bit expensive. Yes, I save money by not paying for plagiarized content, but it runs up when you bulk check content. For a single website or a content writer, this would not be a huge problem, but I seem to have to pull out my credit card way too often.

I was interested in trying out their CopySentry function as well, but it would be WAY too expensive.

Overall: I have run more than 100k articles through Copyscape over the last 10 years. I have tried to find a replacement, but I always run back to CopyScape. My volume these days is way lower though. But back in the heyday of Google Adsense sites, I ran a LOT of content through.

Review: PCWorld

Plagiarism is a scourge of the Internet age, so a free tool to check for student plagiarism sounds like a teacher’s dream come true. However, while the concept is exciting, the free version of PlagTracker is not yet reliable enough to be used with confidence.

PlagTracker works when the user pastes a school paper, or any other piece of writing up to 5000 words, into a text field at the site. Click Start Checking, and the service automatically compares the work with millions of web pages and scholarly articles.

Once a report is generated, click View All Sources to see the links where the allegedly plagiarized material resides. Clicking the link alone may not work; I had to click the icon at the far right of the link to open it.

Review: Microsoft

Before deciding upon a plagiarism checker I tested several and found this to be the best so far. One nifty feature is that you can add it to Word as an Add-on. The only reason I have given it 4 stars rather than 5 is that once you have used up your free word limit you have to pay either monthly or a fixed fee per number of words used and it is rather pricey. Hopefully worth it though for my uni degree.

Review: G2Crowd

What do you like best?

Unicheck has a clean interface, intuitive menus, and great customer support. Having previously used another service, it was impressive to see the attention given to simplicity while still offering the features a school needs for encouraging good writing and avoiding plagiarism. Furthermore, the costs associated with Unicheck services while still allowing the school retention of its documents in its own database(s) makes this service well worth consideration for any school.

What do you dislike?

Unicheck lacks some of the advanced editing/feedback offerings of more expensive services, but it is continually in development and many of those missed offerings are on the immediate roadmap.

Recommendations to others considering the product

Give the trial version of Unicheck a try to explore the interface and make sure the features offered meet your teachers’ needs. Ask lots of questions as you’ll get a good sense of the quality of customer service with Unicheck.

Originaltiy.Ai tool

Have you ever wondered if the content you’re reading is actually written by a human being or by an AI bot?

How can you tell if the piece of content was generated by an AI tool?

Now, you might be wondering why this is important. Well, for starters, Google doesn’t really like AI-generated content, so it’s best to avoid using it on your website if possible.

Plus, if you have a team of content writers working on your website, it’s important to make sure that nobody is submitting content that was generated by an AI tool.

That’s where Originality.AI comes in handy – it’s like having a plagiarism detector specifically designed for AI content. This nifty tool is designed to detect traces of AI-generated content in your writing. In other words, it can tell you if a piece of content was crafted with the help of an AI writer.

How Does Originality.AI work? 

It’s actually pretty simple. You just paste your content into the tool, and it will instantly detect any phrases or pieces of content that were likely generated with the help of an AI writer. It works the same way when you use the tool to detect plagiarized content – it highlights the exact amount of text that was copied from another source.

Orignality.AI Review

Originality.AI is a tool that can be quite useful for those who want to ensure that their content is free of AI-generated text. While it may not be an essential tool for everyone, it can be particularly helpful for those who work in industries where plagiarism and AI-generated content are more common.

The tool works by detecting phrases or pieces of content that were likely generated with the help of an AI writer, and it can also be used to detect plagiarized content. While it may not be 100% accurate, it can provide a good starting point for content creators who want to ensure that their work is original.

That being said, it’s important to remember that using AI-generated content is not always a bad thing. In fact, there are many instances where it can be quite useful, particularly in fields like data analysis and natural language processing. Additionally, it’s important to remember that tools like Originality.AI are just one piece of the puzzle when it comes to creating high-quality, original content.

Overall, while Originality.AI may not be a must-have tool for everyone, it can be a useful addition to the toolkit of content creators who want to ensure that their work is original and free of plagiarism.
