Editor's note

Made for researchers who need to bring English manuscripts up to submission quality; polishing, translation, and the sentence bank are free to use, but VIP pricing is not published, so read the terms before paying.

“Not verified” means evidence is insufficient, not that the capability is absent.

FAQ

Is Bimuyu free?

The client is free to download and use, as stated on the homepage. VIP membership adds 15 perks including full-text polishing and 10 GB of cloud storage, but pricing is not published; confirm inside the checkout flow (checked 2026-07-17).

How does it relate to Xiaolujing?

Same team: Xiaolujing is the English literature reader and Bimuyu is the writing client, and their corpora and citations sync.

Should I use the AIGC-reduction feature?

It can rewrite text to lower AI-detection scores, but academic publishing generally requires honest AI-use disclosure. Use it to improve language, not to conceal AI-generated content.
