One of the worst crimes a writer can commit in the modern-day world isn’t assault but theft. Plagiarism is the biggest form of theft because it’s not just items being stolen, but intellectual rights and properties. The sheer volume of work on the internet means it’s very easy to steal or have ideas stolen from you.
Unfortunately, most plagiarizers aren’t even aware they’re plagiarizing someone else’s work. However, the good news is that there are many plagiarism checker software available that can help you avoid such pitfalls. Here is the best plagiarism checker software for 2023.
1. Turnitin
Because of its wide application by academia, many university students can vouch for the prowess of this online tool . Such is its prowess, detail, and precision that most students can no longer copy assignments cheaply off the net. However, for all the good work that the software does in schools, it’s sold only to institutions and not individuals.
Pros
- Extremely sophisticated
- Detailed enough to handle academic plagiarism
- High accuracy
- Massive database
Cons
- No individual access
2. Grammarly
When it concerns grammar checking and amateur writers, Grammarly is the name on everyone’s lips. However, the tool also includes a plagiarism checker software bundle that has proven quite effective so far. It works exceedingly fast and offers both a paid version and free access. Another exciting feature of this plagiarism checker software is its free switching between British and US grammar.

3. Scribbr
It’s another exciting option for academia. However, unlike Turnitin, Scribbr optimizes more for student-service than institutions and allows individual subscriptions.

5. Quetext

The plagiarism checker software shares a lot of similarities with Grammarly in terms of speed and business model.
