Our verdict

This extension turns foreign-language webpages into Chinese while keeping the original page layout intact, using fast translation for simple sentences and calling a larger model like ChatGPT for complex ones. Every translated passage can be manually edited, saved locally and automatically reused next visit, with a right-click bringing up the original for comparison or re-translation. Free use covers 300 AI translations a month and five contextual word lookups a day, while unlimited translation, more lookups and cloud sync between devices sit behind a roughly 10-yuan monthly membership, and it currently only translates into Simplified Chinese.
