What is a Word Frequency Counter?
A Word Frequency Counter is a free online text analysis tool that scans any piece of writing and counts how many times each individual word appears. It then ranks those words — from most used to least used — and displays the results in a clear, readable table showing each word's count and its percentage share of the total word count. No software to install, no account to create, no technical skills required.
Word frequency analysis is one of the most powerful and widely applicable techniques in text analysis. A content writer can use it to check whether key terms are used consistently and at the right density throughout an article. An SEO professional can verify that target keywords appear with the correct frequency and identify unintentional keyword stuffing. A student can analyze an author's writing style by examining their most-used vocabulary. A teacher can check the reading level and vocabulary diversity of a piece of content before assigning it.
Toolnex AI's Word Frequency Counter goes beyond simple counting. It provides four sorting modes (by frequency, alphabetically, by word length, and rarest first), options to exclude common stop words like "the," "and," and "is" so only meaningful content words appear in the results, case sensitivity control, number filtering, and a minimum word length filter. Every result includes a visual frequency bar, word count, and exact percentage — giving you a complete picture of your text's vocabulary in seconds.
All processing runs entirely in your browser — your text is never sent to any server, stored anywhere, or shared with anyone. Whether you are optimizing an article for SEO, checking keyword density, studying vocabulary patterns, or analyzing a dataset of text documents, the Toolnex AI Word Frequency Counter delivers accurate, instant, and completely private results every time.
Why Use Toolnex AI Word Frequency Counter?
Completely Free
No subscription, no account, no hidden charges. All four sort modes, all analysis options, the full frequency table, and CSV export are available to everyone at zero cost — forever.
Instant Results
Analysis runs the moment you click the button — no server delays, no loading screens. Everything processes locally in your browser at full speed regardless of text length.
Visual Frequency Bars
Each word in the results table includes an animated frequency bar that gives you an immediate visual sense of how dominant that word is relative to the most-used word in the text.
100% Private
Your text never leaves your browser. Nothing is sent to any server, stored in any database, or shared with any third party — completely safe for confidential documents and sensitive content.
Stop Word Filter
Built-in stop word exclusion removes filler words like "the," "is," and "and" so your results focus only on meaningful content words — essential for keyword analysis and content review.
CSV Export
One-click export copies all word frequency results as comma-separated values — ready to paste directly into Excel, Google Sheets, or any data analysis tool for further processing.
Features of Our Word Frequency Counter
4 Sort Modes
Sort results by frequency (most used first), alphabetically (A to Z), by word length (shortest to longest), or rarest first (least used first) — switch instantly to explore different perspectives on your text's vocabulary.
Case Sensitivity Control
Toggle between case-insensitive mode (treating "Word" and "word" as the same) or case-sensitive mode (treating them as distinct entries) for both general writing analysis and technical text processing.
Stop Word Exclusion
Filter out over 100 common English stop words — "the," "a," "and," "is," "in," etc. — with a single dropdown selection, leaving only content words for meaningful keyword density and vocabulary analysis.
Number Filtering
Choose to include or exclude numeric tokens from results. When analyzing prose and articles, excluding numbers keeps the frequency table focused on vocabulary rather than numeric data points embedded in the text.
Minimum Length Filter
Set a minimum word character length from 1 to 5+ to filter out very short words automatically. Set it to 3 or 4 to focus on substantive vocabulary and eliminate noise from two-letter function words.
CSV Export
The Copy as CSV button exports the complete frequency table — word, count, and percentage columns — directly to your clipboard in standard CSV format, ready to paste into Excel, Google Sheets, or Python for further analysis.

Frequently Asked Questions
Yes, 100% free with no hidden charges, no account required, and no usage limits. All four sort modes — Frequency, Alphabetical, Word Length, and Rarest First — plus all options including case sensitivity, stop word exclusion, number filtering, minimum word length, and CSV export are available to everyone at zero cost with no watermarks, forever.
Stop words are extremely common English words that carry little semantic meaning on their own — words like "the," "a," "is," "in," "and," "of," "to," "that," and similar function words. When you enable "Exclude Stop Words," the tool filters these out of the frequency table so results show only meaningful content words — nouns, verbs, adjectives, and subject-specific vocabulary. This is especially useful for keyword density analysis, SEO content review, and vocabulary-focused writing analysis where filler words would otherwise dominate the top results.
No. All analysis runs entirely in your browser using client-side JavaScript. Your text is never sent to any server, stored in any database, or shared with any third party. When you close or refresh the page, your text is gone immediately. This makes it completely safe for confidential documents, proprietary business content, personal writing, academic material, and any sensitive text you want to analyze privately.
Clicking "Copy Results as CSV" copies the complete word frequency table to your clipboard in standard CSV format with three columns: Word, Count, and Percentage. You can then paste it directly into Microsoft Excel, Google Sheets, Apple Numbers, or any text editor or data processing tool that accepts CSV input. Each row represents one word from the analysis. This makes it easy to do further filtering, charting, or processing of the frequency data in your preferred tool.
No hard limit exists. The tool runs entirely in your browser and can handle long texts — full articles, research papers, multiple chapters of a book — without issue. The only practical constraint is your device's available memory, which is not a concern for text sizes encountered in everyday use. Very large texts of tens of thousands of words may take a moment to process but will complete successfully and return accurate results.
Frequency mode shows the most-used words at the top — best for identifying dominant vocabulary and keyword density. Alphabetical mode lists words in A-to-Z order — useful for quickly finding whether a specific word appears. Word Length mode orders from shortest to longest — helpful for readability and vocabulary complexity analysis. Rarest First mode shows the least-used words at the top — useful for finding unique or technical vocabulary within a document. All four modes show the same complete data, just ordered differently.
The Minimum Word Length filter removes words shorter than the selected character count from the frequency table entirely. Setting it to 3 removes one and two-letter words like "a," "I," "at," "be," "in," "it," and "of." Setting it to 4 additionally removes three-letter words. This is useful when you want to focus purely on substantive vocabulary without the noise of short function words, especially when the stop word filter alone is not sufficient for very detailed vocabulary analysis.
Yes, the tool is fully responsive and works on all devices including smartphones, tablets, desktops, and laptops. The layout adapts automatically to smaller screens, all controls are optimized for touch input, and all four sort modes, all analysis options, the frequency table with visual bars, the stats panel, and the CSV copy button work identically on mobile browsers as on desktop with no loss of functionality or features.
