"Used to be amazing, now useless..."

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.

"Lot of false positives..."

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

"Interesting results..."

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

"Ai detection is trash..."

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.

"Inaccurate..."

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!

"plagirism detector sometimes misleading..."

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…..."

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..."

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…..."

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..."

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!
