Copyleaks Plagiarism Checker Review Summary

3 Things Copyleaks Plagiarism Checker Does Well

• Easy to Use Interface: You know, it seems like a lot of folks mention that you don’t really need a manual or anything, the screen is laid out in a way that just makes sense.
 
• Free Plan Available: A few users bring up that there’s a free option, which kind of takes off the pressure if you don’t wanna spend money right away but still need to check a few things out.
 
• Guided Mistake Feedback: I saw that people like how you get to see what you did wrong, so it’s not just about flagging errors, it actually helps you learn from them.
 
• More on how Copyleaks shines below.

5 Big Mistakes Copyleaks Plagiarism Checker Makes

• Bad Customer Service & Refunds: If you try to cancel or get a refund, good luck—you’ll be left waiting for ages, and it’s a pain to get any money back. The support seems to just ignore you or send useless replies.
 
• Expensive Subscription Trap: You have to pay for a whole bunch of credits every month, but unused ones just disappear—no rollovers. You might end up spending lots for credits you never even use.
 
• Inaccurate AI and Plagiarism Detection: Even work you wrote yourself can get flagged as 100% AI or plagiarized. Other tools don’t do this, so it’s super confusing and makes it hard to trust the results.
 
• Not User Friendly at All: There’s hardly any clear guidance on how to use the tool or avoid mistakes. You end up wasting credits just trying to figure out how stuff works, and it’s way too easy to get stuck.
 
• Punishes You for Double Checking: If you try to recheck or scan your own document again, it counts that as plagiarism and uses up even more credits. Basically, you get charged again just for wanting to be sure.
 

What Does Copyleaks Plagiarism Checker Cost?

• Personal Plan – For $16.99 each month, you can scan up to 100 credits, which covers about 25,000 words. It checks for both plagiarism and AI at once, even in 30+ languages. You also get Chrome and Google Docs access, which I found handy. But honestly, those 100 scans don’t go far, and if you forget or don’t use them, the credits just disappear at the end of the month.
 
• Pro Plan – This one’s $99.99 a month. It’s honestly made for groups or teams since you can add up to 25 people. You jump up to 1,000 credits monthly (that’s about 250,000 words). Stuff like full website scans, better filters, translation checking, and fancy dashboards come with it, plus faster support. If you’re just one person, though, this plan is way too expensive, so I didn't really see the value for small users like me.
 
• So, should you buy Copyleaks Plagiarism Checker? Honestly, probably not for most folks, since the credits feel super limited and if you don't use them up, poof—they vanish every month.

Copyleaks Plagiarism Checker Review - What Does it Get Right?

1. Easy to use interface:
   • You open up Copyleaks, and everything is pretty clear and simple. Nothing confusing or hidden.
    
   • Lots of folks say you don’t need a guide to get started, which means less time just figuring stuff out.
    
   • People say all the buttons are where you expect them to be, so you aren’t stuck searching all over the screen.
 
2. Free plan available:
   • You get to try things out without paying, so you don’t feel pressured to buy right away.
    
   • Some users like that you can do basic checks and learn how it works even if you’re on a budget.
 
3. Guided mistake feedback:
   • If you mess up, Copyleaks actually tells you what went wrong; it doesn’t just say “wrong” and leave you hanging.
    
   • People like how you can learn and understand your mistakes, not just fix them for today but maybe avoid them next time.
    
   • This feature makes checking more useful, because you’re actually learning while you use it.

“Very user friendly interface.” ― Roby IN

Copyleaks Review - What Does it Get Seriously Wrong?

• Bad Customer Service & Refunds
  • If you have any issues or want a refund, you’re gonna wait forever. Most of the time, support either ignores you or just sends a basic, unhelpful reply. For something you pay good money for, that’s just not okay.
   
  • From my own experience, once you ask to cancel or refund, it’s like yelling into a void. Good luck getting any action, and don't count on them fixing problems if you pick the wrong subscription or need to downgrade.
   
  • When you do manage to get a response, it’s often “too bad, nothing we can do”—which just leaves you stuck. You shouldn’t have to argue for support or your own money back.
 
• Expensive Subscription Trap
  • You have to buy a chunk of credits every month, but if you don’t use them, they vanish. There’s no rollover, so you end up paying for stuff you didn’t use and you can’t carry it to the next month.
   
  • If you make the mistake of choosing the wrong plan, there’s no easy fix, and you’re forced to pay the minimum again if you run out. It just feels like they want to squeeze more money out of you at every turn.
   
  • From all the reviews and my own headaches, it’s clear you just keep spending—unused credits just disappear, and you might have to buy another big batch even if you scanned once or twice.
 
Here's a review by TommyB IE talking about their experience with the service:
 

“Unfair Business Practices – Do Not Recommend I signed up to CopyLeaks for what I assumed would be a straightforward plagiarism detection service. I paid $16 and was given 100 credits, expecting that to be sufficient for my needs. However, the service is extremely misleading in both functionality and billing. The first scan I performed was completely inaccurate. It flagged everything in my document as plagiarised simply because it wraps all content in quotation marks, regardless of whether it’s actual quoted material or just standard speech formatting. This inflated the plagiarism score and forced me to run another scan. What I wasn’t clearly told is that every new scan consumes additional credits. Even worse, the second scan flagged my document as 100% plagiarised simply because it matched the first version I had submitted — which the system had stored in its own database. So essentially, I was penalised for checking my own work twice. There is no clear guidance or explanation on how to properly use the service or configure settings. By the time I had figured out how to do a clean, correct scan, I had used up all my credits. To proceed, I was required to top up my account by the minimum purchase amount — another $16 — meaning I had to pay twice for a single functional scan. This is, in my opinion, an unfair business model. It’s not transparent, it penalises genuine users trying to check their work, and it locks essential settings behind trial and error at a real cost. I strongly advise others to look for a more honest and user-friendly plagiarism detection service.” ― TommyB IE

 
• Inaccurate AI and Plagiarism Detection
  • It often flags stuff you wrote yourself as 100% AI or plagiarized. Even super experienced writers say their totally original work gets called fake, while other tools say it's just fine.
   
  • The problem is, this kind of false flag makes you super confused and makes it hard to trust anything the checker says. You shouldn't have to doubt your own writing after using a tool like this.
   
  • With results all over the place, it’s risky if you’re using Copyleaks for school or work — it could get you in trouble even if you didn’t do anything wrong.
 
• Not User Friendly at All
  • There’s barely any guidance on how to get a proper scan. You get almost no instructions or tips, so you end up wasting precious credits just trying to figure out how things work.
   
  • Most of the settings are hidden, you’re left guessing, and if you make a mistake you’re out of luck. It’s really easy to get stuck and waste time (and money) going in circles.
   
  • You shouldn’t need a manual just to use a plagiarism checker. It feels like they make it tricky on purpose, which is super frustrating for new users.
 
• Punishes You for Double Checking
  • If you want to double-check your own document or re-scan, they count that as plagiarism and eat up more of your credits. Seriously, you’re penalized for trying to be careful.
   
  • The system saves your first upload, so when you scan again, it matches against itself and falsely calls it copying. You’re forced to pay more just to check your own work a second time.
   
  • This makes you spend way more credits than you should – it’s not fair when you’re just trying to get an accurate result and follow good habits.
 
Here's a review by Chris Fulmer talking about their experience with the service:
 

“The tool was decent at detecting AI content, but you could easily fool it by changing a few words around. Service will not make corrections if you make a mistake choosing plans or upgrading/downgrading, so do so carefully.” ― Chris Fulmer (US)

What Does Copyleaks Plagiarism Checker Cost?

• If you just want the basics, Copyleaks gives you the Personal Plan for $16.99 a month. That’s almost 17 bucks, every single month—no matter if you use it or not. That’s like having a gym membership but never actually going.
 
• You get 100 scan credits, which works for up to 25,000 words per month. But let me tell you, if you don’t use up those 25,000 words, you still have to pay the next month. Your credits disappear at the end of every month—even if you never scanned a single page!
 
• The plan does let you scan for both AI and plagiarism in the same report, and the detection covers over 100 languages for plagiarism and 30+ for AI. Neat, but do you actually need all that every month? I found I didn’t.
 
• You do get some extra perks like the Shared Data Hub and add-ons for Google Docs and Chrome, but honestly, I found these are things you probably won’t use daily unless you’re a super power user.

• This one blew my mind. The Pro Plan costs $99.99 per month—yup, a hundred bucks every month—and that’s before tax in most places!
 
• You get everything that’s in the Personal Plan, plus you can add up to 25 users. Great if you have a team, but even then... a hundred bucks a month? That’s more than most folks pay for Netflix, Hulu, and Disney+ all together.
 
• You get 1,000 scan credits for up to 250,000 words per month. But here’s the kicker—same thing: if you don’t use those 1,000 credits or all those words, you don’t get to keep them next month. Poof, gone.
 
• Sure, you get advanced features like better filtering, full website scans, translation detection, an analytics dashboard, and so-called “priority” support, but from my experience, the core thing you’re still stuck with is hefty monthly payments for something you may or may not use every month.

• If you want just the AI Detector, it starts at $9.99/month. If you want only the Plagiarism Checker, that’s $10.99/month. The combo deal (AI + Plagiarism Detection) is basically the same as the Personal Plan at $16.99/month.
 
• I tried just the Plagiarism Checker by itself, and honestly—paying almost $11 every month, month after month, for something so basic? It felt overpriced, especially since there are lots of tools out there that do the same thing for way less, or just one flat fee.
 
• The only upside is you can get a little discount if you pay for a whole year at once, but that means dropping a bunch of money all at once—and you’re still locked into paying every year.
 
• There is a free version and a free trial, but let's be real—they’re just there to pull you in. Everything useful is paywalled after a couple scans.

• For schools or businesses that want all the bells and whistles, there’s an Enterprise/LMS plan, but you have to talk to sales to even get a price.
 
• I haven’t seen any normal person actually need this, unless you’re running a university or a huge company, which honestly isn’t most of us reading this.
 
• If you thought the Pro Plan was expensive, just imagine what this costs. Plus, these enterprise plans usually come with contracts and extra paperwork. Not my thing.

• Copyleaks charges you again and again every single month, no matter if you use up your words or not. It’s like paying for a whole pizza every month, but you only get to eat one slice and they throw the rest out.
 
• The bottom line? There are way better deals out there, and you don't have to waste money on monthly subscriptions you'll forget about—or regret signing up for.
 
• For example, check out AIDetectPlus—here’s what makes them awesome:

• No subscriptions. With AIDetectPlus, you pay exactly once—no monthly fees, ever.
 
• Credits NEVER EXPIRE. Buy as little as 5,000 or up to 60,000 words at a time starting at just $9, and use them whenever you want—next week or next year, you only pay again if you need more.
 
• All-in-one toolkit. It’s not just plagiarism and AI detection, you also get humanization tools, PDF features, paraphrasing, and more (read the full AIDetectPlus vs Copyleaks review here).
 
• Better value. Instead of burning cash on credits that disappear, you get to control exactly how and when you use your words. No waste, no stress.

#2 - Copyleaks Plagiarism Checker vs Turnitin

• Both Copyleaks and Turnitin will check your work for plagiarism, but honestly, they’re made for pretty different folks.
  • Copyleaks Plagiarism Checker is pretty simple to use and good if you’re someone like me—maybe a student, blogger, or just curious about your own writing. You don’t need fancy training or anything. There’s even a free plan to try.
  • Turnitin, on the other hand, feels more like something schools use. Teachers use it to check essays and assignments. It’s got those official classroom vibes and links up with different school tools.

  • Turnitin is honestly built for teachers and school stuff, with detailed plagiarism and AI checks that fit school rules.

#3 - Copyleaks Plagiarism Checker vs Duplichecker

• Both Copyleaks and Duplichecker help you spot plagiarism, but honestly, they feel pretty different to use.
  • Duplichecker is totally free for basic checks, and you don’t even need to sign up. It’s straight-up quick and simple—perfect if you just wanna copy-paste some text and see if it’s original.
  • Copyleaks is set up more like a pro tool. It’s got more advanced features, but you need an account, and unless you’re using the tiny free plan, you have to pay for credits. It also gives you feedback when it flags stuff, which can be cool if you’re trying to learn.
 
• Where is Duplichecker Better?
  • Duplichecker is super fast, free, and you don’t have to sign up for small checks. It’s a lifesaver for simple copy-paste jobs—you just check, see the results, and move on.
   
  • There’s no pressure to buy anything, and the whole thing is way less confusing than some of those pro tools.
 
• Where is Copyleaks Plagiarism Checker Better? Copyleaks gives you extra explanations for your mistakes, and the dashboard looks a bit cleaner. If you want feedback so you can fix stuff, it’s kinda handy. See more here.

Is Copyleaks Plagiarism Checker Legit?

• Reason #1: Customer Support is a Mess: If you ever want a refund or any kind of help, expect long waits and annoying back-and-forth. Honestly, I felt totally ignored by their support team—it’s like they hope you’ll just give up.
 
• Reason #2: You’re Trapped in Pricey Subscriptions: With Copyleaks, you’re forced to buy a set amount of credits every month, but the unused ones—poof—gone forever. So you’re basically paying for stuff you don’t even use.
 
• Reason #3: Accuracy Issues Make It Hard to Trust: I’ve had original, totally self-written work flagged as AI or plagiarized, which is crazy. It makes you second-guess every result, and that’s just frustrating. Other checkers I’ve tried don’t do that.

“Scammy product. Expensive, not truly effective. And most importantly, and the reason why it's 1 star rather than 3, is how difficult they made it to deactivate the account.” ― Rbrnc IT
