Cons
- Free version is significantly limited compared to premium plans—advanced features like unlimited checks, detailed AI scores, the citation generator, and the AI paraphrasing tool require a paid subscription.
- Language support, while covering major European languages, does not include widely spoken languages like Chinese, Japanese, Arabic, Hindi, or Korean, limiting accessibility for global users.
- No dedicated mobile application mentioned, which may inconvenience users who need to check content on-the-go or prefer mobile workflows for academic and professional writing tasks.
- AI detection accuracy, while advanced, may still produce false positives or negatives as with all AI detection tools—results should be interpreted as guidance rather than definitive proof of AI authorship.
