Quillbot Plagiarism Detector Review

Quillbot’ Plagiarism Detection Quality — 46.1/50 ⭐️⭐️⭐️⭐️⭐️

We are ready to share our thoughts about this plagiarism detector. QuillBot demonstrates high efficiency in detecting human-written text and content sourced from the internet, with detection rates of 91.2% and 99.7% respectively. These figures indicate a strong capability in identifying conventional plagiarism. However, its performance dips when it comes to more nuanced challenges such as AI paraphrased content, where it detected 82.65% of plagiarism but failed to recognize AI involvement. In scenarios involving text modifications, the tool showed some capability by marking anomalies within the text, though it did not attribute these to plagiarism. This nuanced detection suggests QuillBot is highly reliable for straightforward plagiarism but may need further refinement for complex cases involving AI or subtle text manipulations.

Affordability does matter but detecting AI-generated stuff should be a staple now!

CosmicCupcake October 2, 2023

I get that it has some cool features, but what’s the deal with not detecting AI content?! 🤖❌ Kinda crucial in this techy age, no?

QuantumQuest August 31, 2023

46.1/50 on detection quality is not too shabby, but does it really catch those clever little paraphrases? Need some real talk here, peeps.
