3 Things Unicheck Does Well

• Plagiarism Checking: One of the main reasons to use Unicheck is to check if your paper or homework has copied content. This seems to be especially helpful for students.
 
• Assignment Help: Many users find it useful because it makes completing school assignments easier—you can be confident your work is original before submitting it.
 
• Affordable Pricing: The pricing is student-friendly and not super expensive, so even if you’re on a budget you can likely use this tool without worrying about the cost.
 
• Read more about the benefits of Unicheck below.

5 Big Mistakes Unicheck Plagiarism Checker Makes

• Terrible Customer Support & Refund Hassles: If you ever have a problem, don't expect help. The support team doesn't care and getting a refund or canceling is like pulling teeth. They basically say no and leave you on your own.
 
• Expensive Plans That Eat Your Money: Watch out! They lock you in an expensive subscription, and any credits you don’t use just disappear each month instead of rolling over. You'll end up paying a lot for nothing in return.
 
• Credits Vanish With Time Limits: It stinks that you buy pages or credits, but there's a timer ticking. If you don’t use them up fast enough, they're gone forever and you get zero value for your money.
 
• Super Weak Plagiarism Detection: The checker only looks through open access sources and misses a ton of copied stuff. It even marks your references as plagiarized, which is just silly and super confusing.
 
• Relies On Bing, Not Google: Here’s the kicker – it uses Bing’s search and totally misses stuff that’s easy to find on Google. So if you want a real check, Unicheck just doesn’t cut it at all.
 

What Does Unicheck Plagiarism Checker Cost?

• Personal Plan – This plan is $15 for your first 100 pages. It’s pretty easy if you just wanna check a handful of things, but if you need a lot more, it doesn’t go super far, so just keep that in mind.
 
• Cloud Business Plan – Also $15 for the first 100 pages, so the pricing is the same here. It’s meant for business stuff, but honestly you don’t get any extra pages, just maybe a bit more business-y support.
 
• Cloud K-12 & Higher Ed – This one doesn’t even tell you a price, you have to get a custom quote. That can be kind of a hassle, especially if you’re just trying to compare with other options out there.
 
• So should you buy Unicheck Plagiarism Checker? Personally, I think it’s not the best deal since your 100 pages are limited and can get expensive if you need more. There are better-priced tools if you have lots to check.

Unicheck Plagiarism Checker Review - What Does it Get Right?

1. Plagiarism Checking:
   • Not too strict on random matches: You won’t get hit for just matching two random words. It mostly counts stuff that actually looks copied.
    
   • Makes checking easy: If you want to see if your homework or paper is original, it takes just a minute to run it.
    
   • Good for students: Lots of reviews say students find it super handy for checking assignments before handing them in.
 
2. Assignment Help:
   • Avoids unintentional copying: You get to see if anything in your writing is too close to stuff that’s already out there, so you don’t copy by accident.
    
   • You stay relaxed: You don’t need to stress about surprise plagiarism emails from your teachers.

   • Works for most folks: The pricing seems low enough that lots of different people can afford it, not just students.

“A good website to check plagiarism.” ― Sovitou Long KH

Unicheck Review - What Does it Get Seriously Wrong?

• Terrible Customer Support & Refund Hassles
  • If you ever get stuck, the support folks are cold and super unhelpful. When I asked for help, they brushed me off and didn’t care about actually solving my problem.
   
  • When you try asking for a refund, you just hit a wall. They flat out refuse and point to some small print you barely notice when signing up.
   
  • I feel on your own with any issue, and honestly, it’s like they pocket your money and disappear if you complain.
 
• Expensive Plans That Eat Your Money
  • The pricing looks cheap at first, but once you pay, you realize it’s nothing close to free. Every tiny feature is paywalled or costs extra.
   
  • They suck you into monthly plans, and if you don’t use your credits, guess what? You still lose your money, with nothing to show for it.
   
  • I regret wasting money, especially since there are other checkers with better value and actual guarantees.
 
Here's a review by Robert NZ discussing his experience with Unicheck:
 

“If you like using Bing, you'll love Unicheck. Otherwise... Bunch of things. For starters, with a Personal account you can't do Side-by-Side comparisons. Fine, fair enough. But then when I took a close look at the report turns out it missed over 50% of the items that were copied directly from a wide variety of business news sites. For each of them, pasting the text into Google brought up the page in the first result. When I enquired with customer support, the explanation was: "Our system uses Bing search engine, unfortunately some texts are indexed in the Google only". Um, ok. Yeah. I think that pretty much says it all. When I asked about a refund I was told: "Our service is non-refundable. It’s stated in our customer agreement which you had opportunity to read and agreed while creating an account." Guess I missed the part about their reliance on the Bing search engine. Use at your own risk. UPDATE: After saying goodbye to my $10, I tried the same doc again on Scribbr. Yes, it cost $20. That's why I went with Unicheck in the first place. But let's just say you get what you paid for. Scribbr found at least 2x as many items that were copied from websites. Also, I went for it because, unlike Unicheck, they had a 100% Happiness Refund guarantee. So there you go. Good luck.” ― Robert NZ

 
• Credits Vanish With Time Limits
  • The worst part is your credits have a ticking clock. If you don’t use what you’ve paid for right away, they expire and you can never get them back.
   
  • It’s not fair because you pay upfront expecting flexibility, but then they force you to hurry up or just lose out completely.
   
  • I get frustrated because it just feels like a sneaky way to make you keep paying with no real benefit after the first use.
 
• Super Weak Plagiarism Detection
  • Unicheck only checks against open access sources, so it skips huge parts of the internet and misses tons of copy-pasted stuff.
   
  • The weirdest thing? It marks even your list of references as plagiarism, so your honest work gets flagged and you’re left super confused.
   
  • From my experience, it just doesn’t catch real plagiarism, and what it does catch is often just normal citations or quotes.
 
• Relies On Bing, Not Google
  • This tool is stuck using Bing. It can’t find a lot of stuff that's super easy to see with Google, so you’re not really getting your work fully checked.
   
  • Every time I test stuff, I see Google finds way more matches than Unicheck ever could, so it honestly feels pointless.
   
  • The customer service flat out tells you it’s a Bing issue, so there’s nothing you can do to make it better even if you complain.
 
Here's a review by ΝΑΝΤΙΑ CHATZITHEODOROU GR about their experience:
 

“Waste of money. Doesn't detect anything. Of course they don't tell you they only check against open access sources in advance. No refund either for doing nothing.” ― ΝΑΝΤΙΑ CHATZITHEODOROU (GR)

What Does Unicheck Plagiarism Checker Cost?

• This plan starts at $15 each month and all you get is 100 pages to check. That means, even if you don’t actually check 100 pages, you’re still paying the same $15. It’s like paying for a buffet and eating just a sandwich.
 
• If you forget to use your allowance, you can’t roll over unused checks to the next month. The counter just resets, and you’re back to zero. That’s super frustrating, especially for students or freelance writers who might not need that many checks each month.
 
• This plan comes with stuff like an online dashboard, Google Docs add-on, and bulk uploads, but honestly, I find most people just want simple plagiarism checking — all these extra bells and whistles make it look fancy, but they don’t really make the deal any sweeter.
 
• Trust me, after using it for a few months, I started to feel like I was paying rent for a room I hardly use. Super expensive for something you can’t “save” up for later!

• With this model, you can buy packs as you need. The smallest is 20 pages for $5 (which is 25 cents per check — honestly, that adds up real fast!)
 
• If you buy more, you get “discounts,” like 50 pages for $10, 500 pages for $50, 1,000 pages for $80, and a jaw-dropping 10,000 pages for $600. But who needs that many unless you’re literally running a school?
 
• The credits do last for about 6 months, so you’re not forced to use them right away. Still, if you’re an average user, you end up either wasting pages, or burning through your money buying just small packs at the highest per-page cost.
 
• Personally, I found this model super easy to over-spend on, and honestly, there are far cheaper options elsewhere. Also, once the credits expire, you have to buy all over again — there’s no backup plan.

• If you’re at a school, college or university, Unicheck pushes you to get a “custom plan.” There’s no clear pricing — everything is behind a sales call and a special quote depending on how many students or papers you have.
 
• The Essentials plan comes with a big web search database, data encryption, LMS integrations… all that jazz. Decent features, but you’ll only know your cost after talking to sales (and honestly, I’ve never heard of anyone getting a bargain here).
 
• The Support Plus plan adds a bunch of “premium” things like onboarding, training, faster support, and a dedicated account manager. Unless you’re at a huge school, you’ll probably never need all this — but you’ll still pay for it.
 
• Enterprise is for giant organizations; it adds API integrations, custom paper databases, and more. This is really only useful if you’re a massive institution. Otherwise, it just means more $$$.
 
• Some places (like certain universities) have public rates like $1 per student, per year — but that’s often only for big groups, and the average person or teacher can’t get that price.
 
• Long story short, if you’re not in a big institution (or you are but don’t want lots of meetings and red tape), you probably won’t get any good deal here at all.

• Don’t expect a real free trial. At best, you’ll get to check 200 words for free, and after that you’re locked out unless you pay.
 
• There’s no option to pause your subscription or “save up” page checks for when you actually need them. If you skip a month, you just wasted your cash.
 
• I’ve seen people blow through their credits after just a few essays, only to discover that everything is locked behind another payment wall. That’s just not cool in 2024.
 
• Honestly, you end up paying more and getting less flexibility compared to better tools out there.

• There’s honestly way better choices out there that don’t eat through your money every month.
 
• For example, AIDetectPlus gives you a complete plagiarism detection and removal toolbox, and you only pay once — no subscriptions, no “expiring” credits, no unnecessary extras you’ll never use.
 
• You can buy a one-time credit pack (like 5,000 words for $9) on AIDetectPlus, and those credits NEVER expire. Use them now, use them next year, it doesn’t matter.
 
• Plus, AIDetectPlus comes with AI detection, humanization, PDF handling, paraphrasing, and loads more, all bundled together at a price that actually makes sense. Check the facts: AIDetectPlus.
 
• Why throw your money at Unicheck every month and get nothing back when you skip a month? I say go for something that gives you what you pay for — and lets you use it on your own terms.

Is Unicheck Plagiarism Checker Legit?

• Reason #1: Awful Support & Refund Mess: If anything goes wrong, you’re pretty much on your own. The customer service is just plain terrible, and getting a refund or canceling your plan feels impossible. I’ve tried reaching out, but they just brush you off.
 
• Reason #2: Your Money Disappears Fast: Their plans are expensive, and the worst part? If you don’t use all your credits in time, they vanish! You end up paying a lot, and if you forget or get busy for a while, you’ve thrown cash down the drain. No carryover—just gone.
 
• Reason #3: Lousy Plagiarism Detection: The tool isn’t even that smart. It only checks open-access stuff, so it misses a ton of copied content. Plus, it calls your legitimate references plagiarism, which is both confusing and annoying. I ran my own papers, and it missed obvious stuff while flagging things that were perfectly fine.

“One of the worst plagiarism checkers. First off, they are so expensive. They call it as free but when you try to use it, it doesn't show anything. Secondly it would even show references as plagiarized. How is it possible?” ― Malay Ghosh (IN)
