When compared for accuracy with other checkers, Copyleaks comes out on top in all categories.
Corrections made by Grammarly Premium and ProWritingAid could be flagged by our AI Detector when changes have been implemented by the user. With Copyleaks Writing Assistant, they are not flagged by our AI Detector.
In addition to being the best at detecting writing errors, the Copyleaks Writing Assistant also offers API access and the ability to check a wide range of file types unlike many competitors.
Finally, while some tools only support the English language, we can provide corrections in English, Spanish, Italian, French, German and Portuguese. Each of the supported languages have their own unique grammar rules that our model is trained on.
