Hey Noshin, we're sorry to hear that you didn't have an optimal experience with our service.
While we're not fully clear on what went wrong - AI detection is affected by many variables, and works on chunks of text.
Feel free to reach out for our support through https://help.copyleaks.com/s/contactsupport
We'll do anything we can to help sort this out!

Hey, we're sorry you're dissapointed with our service. AI detection works on full blocks of text, so it might seem like that from time to time - it also depends on the length of your text. Shorter blocks of text could get the 0%/100% more often than longer blocks of text. Please feel free to reach out anytime through the support form in our help center: https://help.copyleaks.com/s/contactsupport

If there is anything Less I would give you, you made me pay one year in advance, your app doesnt support arabic, and it always gives either 0% or 100% AI content even for paragraphs I wrote them myself, I don't recommend you as reliable or anything close. There is not even an email to contact administrators when needed

Hey, we're truly sorry that you got different results. Our scanner has advanced scan settings that could yield different outcomes depends on the configuration - your professor might have scanned for different things that you have, which could be the reason.
Completely worthless
Completely worthless! This program is completely worthless as it detects completely human written work as 100% AI generated. I'm sorry, I am a retired Army Veteran who writes in a military writing style, has written training programs, and technical manuals, and has a Masters Degree and working on a second, so I know how to write and do write high quality papers. Yet now that my school has switched to CopyLeaks, my quality of writing is being flagged for 100% Ai generated work. This is BS!

Hey Jacob - we're extremely sorry that this was your experience with our service... AI detection runs on detecting writing styles, and works on large blocks of text - so sometimes smaller chunks of text might generate a 100% signal.

Do not use this
Do not use this, I have been writing an assignment for more than 5 hours with genuine thoughts, and it detects 100 percent AI because of a system. I am just trying to ensure that my work does not get discredited because some website says it is AI.

Hey Alex, we are sorry that you feel your paper was flagged incorrectly. There are many reasons why something would get flagged as AI, e.g., usage of tools like Grammarly.

Nothing but horrible.
Nothing but horrible.
I have been in college for almost a year now and my school makes us check for ai content through copyleaks. Pretty understandable right? No. It is nothing but a disaster every time. Every single time I have to submit MY OWN document on this website it tells me 100% AI content. I have spent countless of hours trying to tweak and change wording and nothing I do works. After 2 hours my document will still be saying 100% AI content. I find it pretty crazy how using “just about numbers” makes my entire document 100%. 3 common words btw.
Another issue i’ve had is that it will give me and my professor two different percentages. I have gotten points deducted and 0% on assignments from using copyleaks but is it not supposed to be the best AI detector? Teachers are learning not to rely on copyleaks anymore and moving onto better websites. I would push it and say copyleaks is ruining my college experience completely since it is one of the worst accurate AI detectors.

I have been trying to buy a monthly subscription from Copyleaks for months, but their service sucks. My questions go ignored. They claim you can pay monthly and cancel anytime, but when I tried to purchase the monthly plan, it only allowed me to pay for the entire year upfront. On top of that, their customer service is terrible—slow to respond and unhelpful when they finally do. Very frustrating experience.

Hey Rachael - we're sorry about your experience with trying to purchase a subscription and failing. This should not have happened - we have thousands of new subscribers per month and were not aware of any issue. Will check it on our side immediately, and also noted your support experience, and will work to do better! So thank you.
Monthly subscriptions are available by switching to a monthly plan using the switcher on the pricing page - just above the plans columns themselves.

I came here for guidance
I came here for guidance, instead I received straight propaganda. Can anyone explain how it's possible for it to flag a sentence I have just created as 100% ai? No, they want to scare you and make u pay for their advanced detection and paraphrasers. Copyleaks, I hate you. 😡👎

Hey Matthew - we're sorry that you feel disappointed like that.
The AI score works on text blocks, not individual words. Our model needs context to detect AI patterns reliably — analyzing word by word would lose accuracy. When a block contains enough AI signals, the whole block is flagged. That means short human-written elements inside the block (a name, a quoted line) may be highlighted alongside the AI text.
Highly formulaic human writing can occasionally mimic AI patterns, but false positives are rare. Treat the AI score as a strong indicator — use your own judgment as the final call.
This software is useless
This software is useless, it detect plagiarism in singe words, in parts of the template my school has forced us to use or in statements i have clearly written myself about my opinion. "I think" should not be flagged, single words should not be flagged. Ive had to remove entire sentences just to appease the software only for it to increase my score somehow.

Just bad. Should let you keep the credit you pay for, or actually, pay for one month with unlimited text you can scan. But surely they care more about their profit.

Hey Luca! Thank you for your feedback. The subscription plans give you access to all of our advanced features, but like any other plan, they have fair usage limits - and this is what the credits are for.
It is your choice on how to use your monthly/yearly limits.
