    Very needed tools as it has become very common to use artificial intelligence and write assignments and blogs for guest blogging and other tasks.
    Also it helps in detection of plagiarism which will prevent misuse of someone else’s creativity.
    Since there are so many paraphrasing tools and they can make almost completely different paragraphs.
    will still these tools be able to detect the plagiarism and ai contents?

    • Jiří Vaněk says

      Most of the tools I’ve tried usually show some percentage probability that the given text was written by an AI. However, I probably haven’t come across a 100% tool that could detect this with a guarantee. And thanks to how language models are improving enormously, I’m afraid it will probably never be possible. Personally, I was afraid of Google, for example, because I sometimes use AI and chatbots for a short explanation on the web. Many people have come up with the idea that Google will be able to detect these techniques and penalize them. This is not happening yet and the question is whether Google will have any tools for this.

  3. Ram E. says

    Personally, I have doubts on the accuracy of any of these AI writing detector tools. I have read a few cases where false positive was reported not just in a work setting but in the academe as well. Arguably, the concensus in the SEO community is also not in favour of these tools.

    • WPBeginner Support says

      There can be room for interpretation for some but these tools can still help quickly identify some of the AI submissions :)


      • Ram E. says

        I agree. I think these tools will be great in detecting AI-written content that has gone through little to no manual review or human edits. But for generated content that was subjected to full-effort human review before publishing, it would be difficult for those tools to do their magic.

  4. Jiří Vaněk says

    Unfortunately, these tools work exceptionally well only with English or very frequently used languages. For instance, they struggle to analyze articles generated in Czech effectively. It’s a pity.

    • Ralph says

      Ahoj! I feel the same about Polish language. Everybody in English can use ChatGPT and similar tools to create great things and whatever more advanced thing in other language sounds like random words glued into sentences with little to no sense.

      • Jiří Vaněk says

        Hi Ralph. Thanks to this, I made a decision to have a bilingual website. Exactly because ChatGPT does English so well, and I’m not as fluent. So, we collaborate closely (if I call AI as my colleague), where I write my blog in Czech, and it provides excellent translations for the English part of the website. Otherwise, beyond English, it’s a great help for creativity. When I get stuck in writing and need inspiration, it excels in Czech, and I believe it can manage Polish as well. I have some colleagues in Poland, and that language isn’t so far from ours. Sometimes, I even understand you :).

  5. Ralph says

    Funny how fast we went from creating content with AI to tools made for detecting it.

    For personal website i feel like it is not very useful, as we know if we used AI. However for bigger websites with teams of content creators it is nice idea to see who is “really” working, and who is trying to cheat the system. Not saying AI content doesn’t have any space on websites, but better control its quality.

    • WPBeginner Support says

      Most certainly, AI can be helpful as a tool for brainstorming and outlining but for direct to content it should be avoided :)
