Never worked once. Just a way to increase sign-in into their website. Nothing much.

Co*****, 2024-10-23

La prueba de 5 documentos de hasta 2500 palabras presenta datos muy completos e útiles. Parece ser muy bueno, pero 29 dólares mensuales por 50 documentos puede no ser una opción práctica y realista para muchos usos.

Cr*****, 2023-07-07

This bookmark is complete trash, doesn't work one bit, and their website is super buggy. Wasted so much time with them.

Extension safety

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

SEO Content Checker: Plagiarism & Readability does not require any sensitive permissions.

Risk likelihood

Risk likelihood measures the probability that a Chrome extension may turn malicious.

Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Chrome extension.
