Volcengine Writing

火山写作 (Writingo) is ByteDance’s free AI writing assistant for English writing improvement, offering grammar correction, rewriting and polish.

Overview

Writingo helps Chinese users write better English: paste a draft and the tool corrects grammar, improves word choice and rewrites sentences with more natural phrasing. Its one-click optimization can polish an entire piece while preserving the author’s intent, and tone adjustments adapt text for academic, professional or casual contexts. The tool draws on ByteDance’s language models with specific tuning for Chinese-English interlanguage patterns. It is free to use and widely adopted by students and professionals.

How It Works

Paste your English draft into the editor and review the flagged grammar and expression issues with suggested fixes. Use one-click optimization for whole-document polishing or compare sentence-level rewrites and keep the more idiomatic phrasing before exporting.

FAQ

Is 火山写作 free to use?

Yes. Writingo is currently completely free, and its core correction, polishing and rewriting features can be used directly at no cost.

Does 火山写作 offer an API?
