Reasons to Use a Turnitin Alternative

You might be wondering about what's actually wrong with Turnitin and why you'd want to use a Turnitin alternative to begin with. Well, unfortunately, despite being developed by a trusted brand in the education sector, Turnitin has quite a few problems that many users have complained about.

A big issue with the Turnitin AI detector is accuracy. Sadly, Turnitin often gets things wrong when scanning text. It has repeatedly been proven to flag AI text as human and to flag human text as AI, which causes a lot of problems for students and teachers who are trying to use this tool to identify cheaters and reward those who are honest in their work. Even the developers behind Turnitin have acknowledged its flaws.

Turnitin reddit review

We actually put Turnitin to the test ourselves to see how well it could handle a piece of human text. We wrote a genuine piece on a simple topic - “Tips for Travel on a Budget” - without any AI assistance and then ran it through Turnitin. Unfortunately, as you can see in the screenshot above, the result was very disappointing, as Turnitin thought that the human text was actually AI.

Turnitin test

Turnitin also has an accessibility issue. A lot of people are blocked from using this tool, as it's only available for those in the educational industry. This means that bloggers, business users, creative writers, and copywriters (among other groups) are completely unable to access Turnitin's AI checker.

All of this means that, if you're looking for a truly reliable and trustworthy AI content detector, you can't really count on Turnitin. It sometimes lacks accuracy and isn't even available for many users, so you may need to pursue an alternative option, like one of the many great AI writing detector platforms listed above.

The Final Words

Overall, since Turnitin has a few problems, you might not want to rely on this tool for your AI scanning needs. Instead, consider a reliable and trusted alternative, like HIX Bypass, which offers faster and more thorough AI checks, as well as humanization benefits.
