What Sets Us Apart
The only plan that provides a management panel and centralized billing; individual users do not need it, and the price must be inquired from the official source.
The interface language is only available in English, German, French, Spanish, Dutch, and Portuguese (confirmed through hreflang on the official website), with no Chinese interface, so zh_support is marked as none. However, the functionality can handle Chinese text: the official website claims that rewriting supports 23 languages and translation supports 40+ languages (the complete language list is not provided on the pricing page). It is available for use in Taiwan, with pricing in USD. As of the check on 2026-08-28, the entire site has a promotion stating "Get 40% off Premium, now through Sept 6". There are iOS and Android apps, including a keyboard app.
