3 Things Duplichecker Does Well

 
  • Grammar Checker: If you ever get stuck with grammar, this tool checks your text for mistakes. You can use it for content in different languages, which is handy if you work with folks from other places.
  •  
  • Report Download: After you check your work, there’s an option to download the results as a report. It makes it simple to save or share your stats without using screenshots.
  •  
  • Multilingual Support: The tool isn’t just stuck on one language, so you get to check grammar and plagiarism in loads of different languages. This can be helpful if you deal with international stuff.

5 Worst Things About Duplichecker

 
  • Customer Service is a Mess: If you run into payment or refund problems, good luck getting any help. You'll probably wait forever, and getting your money back or cancelling is way harder than it should be.
  •  
  • Expensive Subscriptions That Trap You: They lock you into pricey monthly plans, and the worst part is, if you don’t use all your credits each month, they’re gone for good. You basically end up paying for stuff you never use.
  •  
  • Misses Real Plagiarism: Even when you check stuff that’s already published online, Duplichecker sometimes says it’s unique. You can’t really trust its results, which kind of defeats the whole point.
  •  
  • Loads of Annoying Ads: There are just way too many ads everywhere. It’s super distracting and can make you lose your focus when all you want to do is check your work.
  •  
  • Very Basic & Lacks Extra Features: There’s no paraphrasing tool, no AI content detection, and no strong privacy policy info. If you want more than just a basic checker, you’re out of luck here.
 

What Does Duplichecker Cost?

 
Duplichecker Basic V plan screenshot
 
  • Basic V Plan - If you go for the Basic V plan, it’s $25 a month. You get to run 310 searches, which is actually more than the old 250 limit. You can check up to 93,000 words in total (that’s up from 75,000). There’s no API access, and you don’t get extra seats for teammates, so it’s just for you. Also, they’ve got some new features added, but honestly, $25 a month still feels pretty steep for the number of searches and words you get.
  •  
  • Should you buy Duplichecker? I honestly wouldn’t say yes, because your checks are limited and if you don’t use them, they just go away. For the price, it’s not ideal for everyone.
That’s the gist of it! If you’ve got a little more time, stick around and I’ll dive into exactly how useful Duplichecker really is and where it’s not the best deal.
 

Duplichecker Review - Why Do People Use It?

 
Infographic showing the best 3 Duplichecker pros.
 
Let me break down the 3 features people talk about the most:
 
  1. Grammar Checker:
    • If you sometimes slip up with grammar, this tool catches mistakes quickly, so you don’t have to stress about them.
    •  
    • You can use it for many languages, which is especially helpful if you work with folks who don’t speak just English.
    •  
    • People like how it makes checking grammar simple—you just paste your text and get instant feedback.
  2.  
  3. Report Download:
    • You can download the check results as a report, so you don’t need to keep snapping screenshots all day.
    •  
    • This makes saving or sharing your plagiarism stats super easy if you need to show them to someone else.
    •  
    • It’s just a single click and then you can keep the report for later or send it out when you have to.
  4.  
  5. Multilingual Support:
    • Duplichecker doesn’t stick to just English—you can check grammar and plagiarism in lots of different languages.
    •  
    • People who work with international clients find this helpful since they don’t have to jump between tools anymore.

5 Worst Things About Duplichecker

 
showing 5 cons
  • Customer Service is a Mess
    • If you ever have trouble with payments or refunds, get ready for a headache. Their support just takes forever or doesn't help much at all, which is so frustrating when you really need help.
    •  
    • I’ve actually tried to get a refund, and let me tell you, it was a nightmare. You can wait days and still get no answer, so if you expect quick help, you'll just get annoyed.
    •  
    • If you want to cancel or fix a payment mistake, it's way harder than it needs to be. There's no easy way out once they have your money.
  •  
  • Expensive Subscriptions That Trap You
    • Duplichecker makes you buy those monthly plans, but if you don’t use up all your scans, you totally lose them. They don’t roll over, so you’ve just paid for nothing.
    •  
    • If you’re thinking you can buy credits for later, you can’t. They basically force you to pay every month for scans you might not even use, which really adds up quickly.
    •  
    • This really annoys me because there are cheaper checkers out there that don’t make you waste money like this for stuff you never use.
  •  
    Here's a review by Tejas talking about their experience:
     
    “Worst experience… This checker is said to be one of the worst plagiarism checker. Because I have pasted my own blog on it it shown completely unique, that was happy moment for me, later on I have check that same content which was already indexed on my site, it was showing completely unique through another web url. So it just a scam don't use it.” ― Tejas (IN)
     
  • Misses Real Plagiarism
    • I’ve tested Duplichecker and it often says something is unique, even when it’s already out there on the internet. That’s a huge problem if you want to avoid plagiarism.
    •  
    • Many others agree, saying Duplichecker just misses stuff that is actually copied. If you’re using this for serious work, you really can’t rely on it.
    •  
    • I feel like there’s just no point paying for a plagiarism checker if it gets the basics wrong and lets stuff slip by undetected.
  •  
  • Loads of Annoying Ads
    • When you use Duplichecker, you get bombarded with ads everywhere. It slows you down and just gets on your nerves, especially if you’re trying to focus.
    •  
    • I can’t count how many times I’ve clicked something by accident because the page jumps around from ads constantly loading. That just ruins the whole experience.
    •  
    • A plagiarism checker should help you work faster, not distract you with pop-ups and banners all over the place.
  •  
  • Very Basic & Lacks Extra Features
    • You only get basic checking—there's no paraphrasing tool or any sort of AI detection, so you can’t do anything fancy or prevent AI-written text from sneaking through.
    •  
    • If you care about privacy, Duplichecker barely gives info about where your text goes. That always makes me worried, especially when uploading important stuff.
    •  
    • If you want something with more tools or stronger privacy promises, Duplichecker just isn’t for you. It’s bare-bones, and that might not cut it.
  •  
    Here's a review by quetext blog talking about privacy policy details:
     
    “Limited privacy policy details”
By the way, if you're seeking a service that doesn't require a subscription and never lets your credits expire, check out AIDetectPlus. You can also give it a free trial (up to 1000 words!) right here.
 
That concludes this comprehensive evaluation. Interested in exploring more Duplichecker alternatives? But first, let's discuss the pricing!

What Does Duplichecker Cost?

 
Comparison of Duplichecker pricing plans.
 
Ok, let me break down Duplichecker's pricing for you in simple words. They only give you a small trial, and if you want anything useful out of it, you have to pay. Here’s how their main plan stacks up:
 
Basic V Plan ($25/month)
  • You get: 310 searches per month, which sounds like a lot, but you’ll burn through them faster than you think if you’re checking big docs or running lots of files.
  •  
  • There’s a total word limit of 93,000 words per month, so you still bump into a ceiling if you work with lots of content, even though they bumped this up from 75,000 words. But trust me – that number goes down quick if you check stuff daily.
  •  
  • You don’t even get any extra user seats, so it’s just you. If your friends or teammates want to use it, they gotta pay up themselves or you need to share your login. Pretty annoying, right?
  •  
  • There’s no API access in this plan. So if you want to plug Duplichecker into any workflow or app, forget it. I tried, and it didn’t work.
  •  
  • Yeah, they say there are “new features” coming all the time, but honestly, I haven’t seen anything major get added that makes up for the high price.
  •  
  • Bottom line: You’re paying $25 every single month for this. If you don’t use up all your words this month, you don’t get to keep them. Next month you just pay again for the same stuff all over. It’s a bit like just tossing your money at them and hoping you get value.
  •  
  • Honestly, given everything, it just… feels kinda expensive for what you get. There are way better ways to spend $25 on tools like these.
 
Refund & Cancellation Policy
  • Once you pay, that money is pretty much gone. Monthly fees are non-refundable. So if you change your mind or barely use it, you don’t get your money back.
  •  
  • Some rare exceptions exist if there’s a technical bug or you got charged without meaning to, but don’t count on getting a refund unless something goes really sideways.
  •  
  • You can cancel your subscription anytime inside your account. But – and this is big – cancelling only stops the next payment. Your access sticks around till the end of your paid month, but you can’t claw back this month’s payment.
  •  
  • So yeah, if you forget to cancel, or you didn’t like the tool, still out that $25.
So if you’re on the fence about Duplichecker, just keep this stuff in mind. It sounds cool until you realize you’re stuck paying every single month for the same old credits and no rollovers.
 
  • Let me be real: you’ve got better options out there that don’t rip you off with expiring credits or big monthly bills.
  •  
  • Check out AIDetectPlus. First off, it’s just $5 one time to get started, not $25 per month, and you can use those credits whenever you want – no pressure, no expiry.
  •  
  • You get AI detection, humanization, AND plagiarism tools all in one spot. It’s way more flexible, especially if you hate subscriptions, and you only pay again if you need more words.
  •  
  • Oh, and if you want to see how Duplichecker stacks up to AIDetectPlus, check out this comparison – the differences are pretty wild.

What are Some Duplichecker Alternatives?

    • Duplichecker is best if you just want to check for grammar errors or a quick plagiarism scan. It’s got some basic tools and can handle different languages, which is cool if you work internationally.
    • AIDetectPlus is made for folks who need more—students, bloggers, freelancers, or anyone really serious about clean writing. It’s got an AI detector, a full-on plagiarism checker, and even an AI humanizer or plagiarism remover.
  •  
  • Where is Duplichecker Better?

#2 - Duplichecker vs Turnitin

  • Both Duplichecker and Turnitin help you check for plagiarism, but they’re honestly built for very different kinds of people.
    • Duplichecker is super basic and straightforward. It's mostly for folks who just want to copy and paste their text and see if anything’s copied from the internet. If you write blogs, do quick checks for homework, or just want to double-check your grammar, this one's easy to figure out.
    • Turnitin, though, is the fancy one schools and colleges use. It’s made for teachers and students who need reports that are detailed, official, and fit right in with academic rules.
  •  
  • Where is Turnitin Better?
    • Turnitin really shines in schools and colleges. You get trusted plagiarism checks, way more accurate results, and even AI detection—plus it fits right in with classroom tools for assignments and grading.
    •  
    • If you’re a teacher or work in education, I’d say Turnitin is the one to go with. It just has all those extra bells and whistles you’d need for academic work.
  •  
  • Where is Duplichecker Better? Honestly, Duplichecker works fine if you just want a quick, super simple plagiarism or grammar check without signing up or dealing with lots of rules.

#3 - Duplichecker vs Grammarly Plagiarism Checker

  • Both Duplichecker and Grammarly Plagiarism Checker look for copied content, but they have their own vibes.
    • Duplichecker is super handy for folks who want a quick, simple plagiarism scan. There’s a free option that lets you check up to 1,000 words a go, so you don’t have to spend anything just to try it out. If you go for a paid plan, you get more checks, grammar help, and even downloadable reports.
    • Grammarly Plagiarism Checker is part of the bigger Grammarly Premium package. That means you’re also getting grammar suggestions, spelling checks, and writing advice all rolled into one neat tool. There’s no free plan for plagiarism, though—you’ll need to pay for Premium to use it.
  •  
  • Where is Grammarly Plagiarism Checker Better?
    • Grammarly does way more than just check for copying—it also helps fix your grammar, suggests better words, and gives you tips on your writing style. So if you want a coach for all your writing, Grammarly is probably the way to go.
    •  
    • It's awesome for students or anyone who wants to write better and catch mistakes, not just plagiarism stuff.
  •  
  • Where is Duplichecker Better? Duplichecker is great if you want quick and easy plagiarism checks without spending money. If you’re not after fancy grammar advice and just want to see if your stuff is original, the free plan is perfect.

Is Duplichecker Legit?

Jim Carry saying No
 
Short answer - Honestly, NOT REALLY!
 
Here’s why I feel that way:
  • Reason #1: Customer Service is a Mess: If you ever need help with payments or refunds, good luck—support is super slow (if they even reply), and canceling or getting your money back is way harder than it should be. From my own experience, it feels like they're trying to avoid helping at all.
  •  
  • Reason #2: Expensive Plans That Waste Your Money: You’re basically forced into these pricey monthly subscriptions, and if you don’t use all your credits, they’re gone at the end of the month. So you’re paying for stuff you don’t even use. It really adds up over time, and I hated seeing my credits just disappear for no reason.
  •  
  • Reason #3: You Can’t Trust Its Results: Sometimes Duplichecker misses obvious plagiarism that’s published online! It’ll just say your text is unique even when it totally isn’t. That means you can’t really count on it to catch what matters, and honestly, that kind of defeats the whole reason for using it.
Here's a review by quetext blog talking about their ad-heavy experience:
