Best AI translation skills for books, articles and blogs (2026)

Updated October 2026. Each skill below was read from its own SKILL.md on GitHub on 18 October 2026.

The best AI translation skills do one thing a plain "translate this" prompt does not: they keep the shape of your document. Headings, links, frontmatter, footnotes, the name of your product spelled the same way on page one and page two hundred. Here are three free, open-source skills on AgentAlley, each built for a different size of job.

A skill is a folder with a SKILL.md file that an agent such as Claude Code loads when your request matches it. You install it once, then ask in plain words: "translate this chapter into Spanish".

1. translate-book

translate-book by deusyu (MIT) is for whole books. Its description says it takes PDF, DOCX or EPUB, converts the input into Markdown chunks, translates the chunks with parallel sub-agents, then puts the result back together as HTML, DOCX, EPUB or PDF.

Good for: long documents that are too big for one pass: a book, a manual, a long report.

The catch: splitting into chunks is what makes a book possible, and it is also where terms can drift between chunks. Read the joins between sections, and check names and key terms across the whole output, not just the first chapter.

2. baoyu-translate

baoyu-translate by JimLiu (MIT) is for articles and single files. Its description lists triggers in English and Chinese, accepts a URL or a file, and offers three modes: quick, normal and refined, plus a custom glossary.

Good for: people who translate articles between Chinese and English often, and want to pick speed or care per job.

The catch: many of its trigger phrases are Chinese, and the examples in the description lean toward Chinese and English. It reads as built first for that language pair.

3. blog-translate

blog-translate is from AgriciDaniel's claude-blog collection. Its description is about translating existing blog posts into one or more languages while keeping the Markdown structure, frontmatter, JSON-LD schema and image and chart embeds, and localizing keywords, meta tags, numbers, dates, currencies and quote styles per locale. It also says it flags machine-translation patterns.

Good for: site owners who publish in more than one language and do not want a translated post to lose its meta description or break its schema.

The catch: it expects a blog post in Markdown. For a PDF or a Word file, one of the other two fits better.

Which one to pick

• A whole book or long manual: translate-book.
• An article, a page or a URL, often Chinese and English: baoyu-translate.
• Blog posts you publish on a site: blog-translate.

What no skill does for you

A skill can keep structure and terms consistent. It cannot tell you whether the result sounds right to a native reader. For anything public, have one person who reads the target language check a sample before you publish the rest. Build a short glossary of the words that must never change, such as product names, and give it to the agent at the start; two of the three skills above already make room for that.
