User reviews

Users generally find NSFW Filter effective at blocking most explicit images using AI, appreciating its privacy and free access. However, common issues include incomplete filtering coverage, lack of video support, occasional false positives, and limited management options for whitelists/blacklists. Users also note it doesn't censor profile pictures or work fully on all sites like Twitter/X and Discord. Despite some slow performance and minor glitches, the extension is favored for its ongoing improvements and helpfulness in reducing exposure to unwanted content.

Расширение работает неплохо, но над точностью выявления наготы нужно ещё поработать. Также было бы классно, если бы был удобный интерфейс для управления страницами-включениями/исключениями наподобие того, что реализовано в расширении SmartProxy.

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.

NSFW Filter requires a few sensitive permissions. Exercise caution before installing.

Risk impact analysis details

Risk likelihood

Risk likelihood measures the probability that a Chrome extension may turn malicious. This is determined by the publisher and the Chrome extension reputation on Chrome Web Store, the amount of time the Chrome extension has been around, and other signals about the Chrome extension. 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.

NSFW Filter has earned a fairly good reputation and likely can be trusted.
