Awful company, beware. After using the product with a paid subscription for 10 months, they suddenly stop offering the A.I detection functionality and leave me with a useless product, avoid at all costs!

I write for a living and am not allowed to use AI. Curious, I checked to see if Copyleaks would say AI detected. Everything I checked said AI detected. I even wrote a 12-sentence short story, and it noted AI detected. What trash software and big companies are probably using this to detect if people are writing or using AI. Can you imagine if someone applied for a writing job and the potential employer entered their samples in this useless software and it said AI detected? Awful.

Trash AI detector. It flags 100% handwritten text (whitout any online ideas) as 100% AI text. If you paraphrase an article, yeah it doesn`t flag it as stolen content but as AI written. I do NOT recommend it to no one, not even for my enemies.

I don’t even want to give 1 star to copyleaks. I don’t know why many companies use this tool to check AI when it shows 100% human written text as 100% AI. There are so many bugs I cannot even mention them all. Overall, its a completely useless app, not at all reliable, and gives inaccurate results.

If I could give 0 star I would. Copyleaks system is very bad. I wrote two contents, 1 with Ai and 1 completely from my head. Guess what! Copyleaks flagged both of them as 90 percent AI. Even the one I wrote without a single drop of online writing tools including Grammarly. This just goes to show how flawed their system is. DON’T EVER USE IT!!

Fake website—do not trust this platform. My AI content is consistently dedicated, and every single word is crafted by the writer. Authentication needs improvement. Do not rely on this site for an AI content-dedicated checker.

most troublesome app in the whole world. this app is a pain to use and the quality is terrible iv never seen a app worse than this

useless. it simply flags anything as ai.

I've been using this software for a while now. Must say that IA detection is not accurate, however, it can identify if a machine wrote the text. Regarding plagiarism, the paraphrases identification system is really bad. I do not recommend this software for plagiarism check.

It's not accurate, How can it detect my name as AI

Used to be brilliant, out of hundreds of articles that were all completely hand-written Copyleaks would only flag one or two as AI. The systems have obviously changed since though, as the tool is now utterly useless. Flags every other manually written article and if I rewrite the paragraphs it flags, it then highlights even more that it hadn't highlighted before. Such a shame they've changed the algorithms, as it was perfect before but questionable now.

Original content is getting marked as AI content! Not reliable as a AI detection tool.

I wrote about 2k words by hand and Copyleaks said 80% of my content was written by AI. How interesting.

Ai detection doesn't work at all. I tried with 5 other websites, and they were brilliant, but this flagged every sentence and gave no explanation as to why.

I wrote 2 sentences (with my actual brain). Copyleaks said it was AI-generated. The sentences were: The Day of the Dead celebration originated in South America, but it is celebrated in other countries too. Some countries that celebrate the Day of the Dead are Mexico, Italy, Brazil, India, Haiti, Columbia, Spain, Ecuador, the United States, El Salvador, Canada, Nicaragua, Philippines, Guatemala, Peru, Bolivia, Australia, and Ireland. Like WHY would they think a human couldn't write something like that??!! It's so basic!

A completely original abstract in my published article is detected by copyleaks as 98% plagiarism classifying it as "one to one exact wording in the text". Be careful, sometimes your published abstract will appeare on your references' journal website causing these faule detections

Presque tout texte est semble t'il généré par IA, qu'il soit écrit par un humain, par une IA ou écrit par un humains avec une correction partielle.

100% False Positives To test it, I wrote random paragraph. Almost BS. It said 100% AI. I tried with a few others. I mixed AI and Human writing, again it said 100% AI I wrote gibberish, even then it said 100% AI I guess that's always the case. Pity any student who is judged because of this app/software

The AI content detection platform isn't reliable in my own experience. I was thinking of purchasing and tested the free version with the following scenarios of all around 4-500 words each. Completely AI written Around 50% AI written Completely human written All three were flagged as all AI content (I do naturally write quite formally, however I don't beleive I'm a robot!) The AI content production and detection market is fast evolving so I don't blame Copyleaks for this, as all companies have more work to do on products like these.

Not at all reliable. If I run one piece of content through copyleaks several times, the result changes each time. The portion that wasn't red earlier, suddenly gets flagged as AI-written. Even entirely human written content is AI. It's a joke!
