+# How to Use the Online Word Counter
+
+This online word counter is built for Chinese writing, English writing, SEO content, social media posts, product copy, blog articles, abstracts, and marketing drafts. Paste text into the editor to instantly count Chinese characters, English words, total characters, characters without spaces, paragraphs, sentences, punctuation, numbers, lines, and estimated reading time.
+
+All counting runs locally in your browser. Your text is not uploaded to a server, which is useful for unpublished articles, contract drafts, product copy, internal notes, and campaign content.
+
+## What It Counts
+
+- Chinese characters: useful for Chinese articles, titles, summaries, and social posts.
+- English words: useful for English articles, emails, essays, and documentation.
+- Characters and characters without spaces: useful for SEO titles, meta descriptions, and platform limits.
+- Paragraphs, sentences, and lines: useful for readability and structure checks.
+- Reading time: estimates how long the text takes to read based on Chinese and English content.
+- Social media limits: checks X / Twitter, Threads, Xiaohongshu titles, WeChat titles, SEO titles, and SEO descriptions.
+
+## Steps
+
+1. Paste text, or upload a `.txt`, `.md`, `.json`, or other text file.
+2. Review the live statistics on the right.
+3. Use the platform limit bars to see whether the text is too long.
+4. Copy the report or download a JSON report for records.
+
+## Common Use Cases
+
+Use this tool to check whether a Xiaohongshu title is too long, whether a WeChat title fits, whether an SEO title or meta description is search-friendly, how many words an English article has, how many Chinese characters a draft contains, and whether the estimated reading time is appropriate. It is useful for frontend developers, marketers, editors, SEO writers, and content creators.
+
+## Counting Rules
+
+Chinese counting focuses on Han characters. English counting focuses on English words. The mixed word count combines Chinese characters and English words to estimate mixed-language copy length. Platform limits can change over time, so the social media limit checks are practical writing references rather than official publishing rules.

+# 在线字数统计工具怎么用
+
+这个在线字数统计工具适合中文写作、英文写作、SEO 内容、社媒文案、产品介绍、论文摘要、博客文章和运营内容检查。你可以把文本粘贴进输入框，实时查看中文字符数、英文单词数、字符数、去空格字符数、段落数、句子数、标点数、数字数量和阅读时间。
+
+统计过程全部在浏览器本地完成，不会上传文本内容。对于未发布文章、合同草稿、产品文案、账号运营内容和内部资料，本地统计更安全。
+
+## 支持哪些统计
+
+- 中文字符统计：统计汉字数量，适合中文稿件、标题和摘要。
+- 英文单词统计：统计英文 words，适合英文文章、邮件和论文。
+- 总字符数和去空格字符数：适合 SEO 标题、Meta Description、社媒标题限制。
+- 段落、句子、行数：适合检查文章结构和可读性。
+- 阅读时间：按中文和英文阅读速度估算读完需要多久。
+- 社媒长度限制：显示 X / Twitter、Threads、小红书标题、公众号标题、SEO 标题和 SEO 描述长度是否超限。
+
+## 使用步骤
+
+1. 粘贴文本，或上传 `.txt`、`.md`、`.json` 等文本文件。
+2. 查看右侧实时统计结果。
+3. 根据社媒长度限制进度条判断是否需要删减。
+4. 复制统计报告，或下载 JSON 报告用于归档。
+
+## 常见使用场景
+
+你可以用它检查小红书标题是否太长、公众号标题是否超出建议长度、SEO 标题和描述是否适合搜索结果展示、英文文章大概有多少 words、中文文章有多少汉字、博客阅读时间是否合适。对于前端、运营、编辑、SEO 和内容创作者，这类字数统计工具可以减少来回复制到多个平台检查长度的麻烦。
+
+## 统计口径说明
+
+中文统计以汉字为主，英文统计以英文单词为主。混合字数会把中文字符和英文单词合并，用于估算中英文混排内容长度。不同平台的长度规则可能会调整，工具里的社媒限制用于写作时快速参考，最终发布前仍建议以平台实际提示为准。
