统计词 / 字频并按次数排序，显示 Top N 与占比条；中文逐字、英文按词统计；可排除停用词与纯数字、加入自定义停用词，支持 N-gram。Counts word/character frequency sorted by count with Top N and share bars; Chinese counted per char, English per word; excludes stopwords/digits, supports custom stopwords and N-grams.
📚 什么是词频统计与 N-gram？📚 What are word frequency and N-grams?
词频统计的是「哪些词出现得多」——是文本分析、SEO 关键词研究、语言学习与写作自查的基础指标。英文按空白切分即可（连字符/撇号词如 don’t 会整体计数）；中文没有天然分词边界，本工具采用「逐字统计」避免引入误分词，若需整词分析可改用 N-gram（如 2-gram 会把「文本工具」拆成 文本·本工·具 等相邻字对，能发现高频搭配）。Word frequency tells you which words dominate — the basis for text analysis, SEO keyword research, language learning and writing self-review. English splits on whitespace (apostrophized words like don’t count as one); Chinese has no natural word boundaries, so this tool counts per character to avoid mis-segmentation — for phrase-level insight use N-grams (e.g. 2-grams of 文本工具 produce the adjacent pairs 文本·本工·具, revealing high-frequency collocations).
占比条展示每个词占总词数的百分比（条形长度按最高频词归一化）。停用词是「的/了/和」这类高频但信息量低的虚词——排除后剩下的往往是主题词；中文停用词表默认内置约 60 个，也可自行添加。排除纯数字、最小长度等筛选可进一步聚焦实质内容。Share bars show each word’s percentage of the total (bar length normalized to the top word). Stopwords are high-frequency but low-information function words like “the / of / and” — removing them leaves the topical words; ~60 Chinese stopwords are built in and you can add your own. Filters like excluding pure digits and minimum length further focus on substantive content.
