Best Plagiarism Checker Reviews: Only Top Tools Offered

Finding the best plagiarism checker for students is important. It’s a known fact that students who write academic essays on a daily basis need to know how original their work is. Various companies try to take advantage of this and offer their tools. Some of them are safe, but many others aren’t. You might be ripped off, lied to, or presented with a similarity report that’s completely made up. We decided to explore the market and find the most reliable plag scanners. Our team personally tested hundreds of options, and we settled on ten best ones.

Top 10 Plagiarism Checkers in 2022

1. Plagtracker

This central page of this website doesn’t have a good design, which might be a turn off for many students. It’s overwhelming and garish. Still, it’s one of the best plag checkers we’ve tested, and here’s why. It doesn’t cost anything, so students could use it as many times as they want. The maximum amount of time you’ll have to wait for is just one minute. It’s much less for shorter texts or essays with average length. This best plagiarism software issues a detailed originality report where you can see how much of your text is unique, what is cited incorrectly, what is plagiarized, etc. Plagtracker uses an extensive base of online and scanned sources to determine uniqueness percentage, and we found results to be extremely accurate.

Price: Free

Accuracy: High

Database: Extensive

Usability: Tacky design and some bugs present

Pros

• Students don’t have to pay

• Detailed plag report

• Great accuracy

• Quick results

Cons

• Garish design

• Website lags at times

2. Copyleaks

This is one of the best plagiarism checkers that supports 100 different languages, which is definitely a big advantage. Both American and international students will find it useful. The problem is, you have to create an account for checking your text. It doesn’t take long, but it’s still an obstacle most of us would like to avoid. After this, the work of this scanner was great: it tested our essay through several large databases and made correct conclusions. Similarity percentage was accurate, and the tool even found the article we were using despite it being obscure and not available on many sites. There are many options available: students could copy and paste their text, upload it, create a link to it, etc. Note that everything is free only for a trial with a limited amount of pages (about 10). If you like how Copyleaks works, want to keep using it, and hope to see a more detailed report, you could upgrade your account.

Price: Sample trial; after that, $10.99 for checking 100 pages per month or $109.90 for 1200 pages per year.

Accuracy: High

Database: Extensive

Usability: You need to create an account

Pros

• Quick work

• Many databases used

• High degree of accuracy

• Free trial available

Cons

• Making an account is a must

3. PlagScan

This is the best site to check plagiarism if you need specific formats. For example, it’ll convert your file into PDF to let you download or print it as proof that your work is fully original. Like with a previous plag detector, you’ll need to create an account, but you could also link your already existing social media account to it. With it done, you should specify in what way you’d like to upload your text: through the web, your desktop, or by copy pasting it. Give it a name and wait for results. Results are displayed in three colors. Green means impressive originality, yellow is for moderate plagiarism, and red is for extreme cases. Our essay was rightfully flagged in red. PlagScan found all issues and offered to take a look at the detailed report. It searches through online databases and libraries, so it could detect even the unknown bits of stolen content.

Price: Sample trial; afterward, 24 pages cost $5.99, 70 pages cost $12.99, 160 pages cost $24.99, etc.

Accuracy: High

Database: Extensive

Usability: Account needed

Pros

• Texts are checked swiftly

• Extensive search across databases

• Great accuracy percentage

• Cheap prices

• Sample trial present 

Cons

• You need to pay for this software

4. Grammarly

Grammarly is popular — everyone knows about it. We don’t find this surprising as it is truly one of the best sites to check for plagiarism. Simple design, friendly interface — students quickly figure out how to use this scanner. From drawbacks, they need to create an account, but they could also link their Google account to access Grammarly. Even then, though, they won’t be able to use plag detector. Sample version gives you an automatic proofreader, but if you want to check text for plagiarism, you’ll need to pay. From good news, prices aren’t expensive, and results are outstanding. Grammarly clearly explains what’s wrong, which parts of content are original, and what you should do to improve your text. We were pleased with results, so we made it a part of our top plag scanner review.

Price: Basic account costs $12 per month

Accuracy: High

Database: Extensive

Usability: Account + paid subscription needed 

Pros

• Popular software with many positive reviews

• Many features

• Precise plag finder

• Affordable prices

Cons

• No opportunity to use plag checker without paying

• No free trial

5. Quetext

This is a simple and pleasant best plagiarism detector. It doesn’t require any kind of registration: just follow the link and you’ll see a welcoming empty box. Fill it with your text and start checking it. Using this program is completely free, even if your essay is long. We have no idea how many databases Quetext searches, which is unfortunate, but it shows accurate results. Every time we tried it with different articles, we got correct percentage. There aren’t many features and the report itself is pretty laconic, but if you want to know how original your text is, it’ll serve this need. 

Price: Free

Accuracy: High

Database: Unknown

Usability: Simple in use 

Pros

• Functional design

• Best plagiarism checker free online

• Highly accurate results

Cons

• Unclear which databases are covered

• Limited service

6. Duplichecker

This top plagiarism checker is pretty diverse. Its system is functional: people could upload documents in different formats, check originality of a webpage via its URL, ask for grammar help, etc. There is no need to log in or create an account — all you’d have to do is tick the “I’m not a robot” box. The issue is with speed. It might take some time before your report is ready. If your text has plagiarism, you’ll be offered a free paraphrasing tool, which is great. Apart from that, though, the free version is limited. Students can check only short texts and only for a specific number of times. Price for pro version isn’t high, but there are some nuances that you should consider. For instance, with a basic tariff, you would be able to do just 10 searches, not more. Results are mostly accurate, but there is a slight deviation. It’s not significant but you should still keep it in mind.

Price: Free limited version & basic plan starts with $10 per month

Accuracy: Moderate to high

Database: Extensive

Usability: Diverse and clear in use  

Pros

• Many options to choose from

• Good results

7. Plagramme

If you’re a college student looking for a paid anti-plag tool, you might like this plagiarism checker best. It’s been developed specifically for students and educators, and this is something you should indicate when creating an account here. It doesn’t take long to register, but it’s still something you must do — otherwise, you’ll be able to check just several sentences, and results won’t be good. Once you’re done, Plagramme will offer you to pick between regular or deep check. The former is free, the latter costs $1 or $1.50. For free version, you’ll have to wait in a queue. It could take up to 10 minutes and it’s a huge drawback. Seeing a detailed report is extra $5. But if you’re willing to pay, a lot of features become available, and you could get really great insights here. There is also professional help available at any moment. Accuracy is very high no matter what text you’re checking.

9. UniCheck

Lots of colleges and universities trust this best plagiarism checker software in particular. We can’t say it was the absolute best: website looks respectable, but it works slowly. Students must create an account, and if they want to log in with Facebook, it doesn’t work for some reason. They should also pay — no free version is available. But we appreciated the variety of options and unique thoroughness of plag reports that become available upon making a payment. After you upload your file, you can see what’s wrong with it in all details. You could check even 10K pages or more, so the plag machine is really efficient and fruitful. We found it to be effective, too: its accuracy is impressive.

Price: Starting with $5 for 20 pages

Accuracy: High

Database: Extensive  

Usability: Clear

Pros

• Many positive plagiarism checker reviews online

• Very detailed reports

• Huge volumes of pages available

• Affordable prices

 Cons

10. Scribbr

You probably recognize the name of this platform. Scribbr is a popular choice among people all over the world, and it has good plagiarism checker. You cannot use it without paying, so it’s a disadvantage, and the generation of a report might take 10 minutes. It’s a lot for those who want to be done with their task quickly. Another problem is that the price is expensive for those who have short documents. Minimal package starts with 7500 words, so even if you have an essay with 400 words, you’ll have to pay as if for 10+ pages. But apart from these facts, Scribbr plag tester is excellent.  It offers precise and detailed reports — you can see an example on a screen shot above. Every plagiarized sentence is underlined and each source is given a number, so it’s easy to see what you got from which website. Suggestions, advice, and other useful features are present, and there is a big volume of pages provided. You could even test your novel here to make certain it’s unique.
