Metaso's Xiezuocat — pro-grade Chinese writing assistant with industry-leading 校對 / 錯別字 / 改稿 features
Part of this entry was LLM-drafted and is being polished.
Xiezuocat (literally 'writing cat') is Metaso's pro Chinese writing assistant, sister product to the Metaso AI search engine. Where it dominates: Chinese proofreading and editing — picking up 錯別字 (wrong character substitutions like 在 vs 再), grammar issues specific to Mandarin, awkward phrasing, redundancy, and inconsistent terminology in long documents. The Western Grammarly equivalent doesn't exist for Chinese; Xiezuocat fills that gap. It also does AI Chinese article continuation, academic-paper polishing (very popular with Chinese grad students), and 降重 (paraphrasing for plagiarism reduction — a specifically Chinese academic use case). Free tier handles ~5k words / day; Pro unlocks unlimited + heavier features.
Editor's verdict
Best Chinese proofreading tool, period. Nothing else (Chinese or Western) catches Mandarin-specific errors at this depth. If you write or edit long Chinese content (公文 / 論文 / 公司報告 / 出版物), this saves hours per document. Doesn't replace ChatGPT / Claude for ideation — those still dominate creative drafting.
