What is the Word Frequency Cloud?
Generate a word cloud from text frequency and instantly see which words dominate your content. Paste any text, upload a file, or load the sample — our analyzer counts every word, filters stop words, detects multi-word phrases, and renders an interactive visual cloud where size equals frequency.
What Is a Word Frequency Cloud?
A word frequency cloud (also called a tag cloud or word cloud) is a visual representation of text data where each word's font size reflects how often it appears in the source text. Words that occur more frequently are displayed larger and more prominently, making it easy to spot key themes, recurring topics, and dominant vocabulary at a single glance.
Unlike basic word cloud makers that only produce an image, our tool gives you the complete picture: an interactive cloud you can hover over for exact counts, a filterable frequency table with percentages and visual bars, and one-click export to CSV, JSON, or SVG.
Key Features
- Live analysis — results update instantly as you type or change options, no button to click
- N-gram detection — analyze individual words, bigrams (two-word phrases), or trigrams (three-word phrases) to uncover meaningful collocations like "machine learning" or "customer service"
- Smart stop word filtering — automatically removes ~280 common English function words (the, is, at, which…) so your cloud highlights what matters; toggle off or customize anytime
- Custom exclusions — add your own words or phrases to filter out domain-specific noise
- Case-sensitive mode — treat "Apple" and "apple" as distinct words when you need precision
- Unicode-aware tokenization — handles accented characters, CJK scripts, contractions (don't), and hyphenated terms (well-being) correctly
- Seven color schemes — Ink, Sunset, Ocean, Forest, Monochrome, Rainbow, and Pastel
- Three orientations — horizontal, mixed, or vertical text layout
- Interactive cloud — hover any word to highlight it and see its exact occurrence count
- Filterable frequency table — search, sort, and scan every word with count, percentage share, and visual frequency bars
- File upload — load .txt, .md, .csv, .json, or .log files directly
- Multiple export formats — download frequency data as CSV or JSON, export the cloud as SVG

How it works
Our word frequency cloud generator processes your text through a six-stage pipeline — from raw text to an interactive, exportable visualization. Everything runs client-side in your browser, so your data never touches a server.
Stage 1: Tokenization
The first step breaks your raw text into individual tokens (words). The tokenizer uses Unicode-aware regular expressions that match letter sequences across all scripts — Latin, Cyrillic, CJK, Arabic, and more. It intelligently preserves:
- Contractions — "don't", "it's", "we'll" stay as single tokens
- Hyphenated words — "well-being", "state-of-the-art" remain intact
- Numbers — optionally included or excluded via a toggle
- Accented characters — "café", "naïve", "résumé" are handled correctly
Leading and trailing apostrophes or hyphens are stripped, and by default all tokens are lowercased so "Hello" and "hello" are counted together. Enable case-sensitive mode to treat them as separate words.
Stage 2: Stop Word Filtering
Common function words — articles, prepositions, pronouns, and auxiliary verbs like "the", "is", "at", "which", and "on" — appear frequently in almost any text but rarely carry meaningful content. The tool ships with a curated list of approximately 280 English stop words (based on the NLTK stop word set plus common contractions and filler verbs).
- Toggle filtering on or off with a single switch
- View the full list via the expandable "stop words" panel
- Add custom exclusions — enter your own words or phrases (comma or newline separated) to filter out domain-specific terms, character names, or any noise
For n-gram analysis (bigrams and trigrams), stop word filtering works slightly differently: phrases that start or end with a stop word are removed (e.g. "the machine" and "learning the" are filtered, but "machine learning" is kept). This preserves meaningful phrases while discarding noise.
Stage 3: N-Gram Generation
Beyond single-word analysis, the tool can detect bigrams (two-word phrases) and trigrams (three-word phrases). This reveals meaningful collocations that single-word counts miss:
- Bigrams uncover pairs like "machine learning", "customer service", "data science"
- Trigrams capture longer phrases like "artificial intelligence", "user experience design"
N-grams are generated using a sliding window over the token sequence, then filtered for stop words at the phrase boundaries. This is particularly valuable for SEO keyword research and qualitative text analysis where phrases carry more meaning than individual words.
Stage 4: Frequency Counting
Each surviving token (or n-gram) is counted. The tool calculates:
- Raw count — how many times each word appears
- Percentage share — the word's proportion of all analyzed tokens
- Rank — sorted by frequency (descending), with alphabetical tie-breaking
A minimum frequency filter lets you surface only words that appear at least N times — useful for large texts where you want to ignore one-off mentions. A minimum word length filter removes short tokens that may slip through.
Stage 5: Cloud Layout Algorithm
Rendering the cloud is the most technically interesting step. The tool uses an Archimedean spiral placement algorithm with axis-aligned bounding box (AABB) collision detection:
- Sort words by frequency (highest first)
- Scale font sizes logarithmically — the most frequent word gets the largest font, the least frequent gets the smallest, with a logarithmic distribution that prevents the smallest words from becoming unreadable
- Measure each word's pixel dimensions using a hidden HTML5 canvas context for accurate width/height calculation (not a rough character-count estimate)
- Place the first (largest) word at the center of the canvas
- For each subsequent word, spiral outward from the center in an Archimedean pattern, testing each position for collisions with already-placed words
- When a non-overlapping position is found (within canvas bounds), the word is placed; if the spiral completes without finding room, the word is skipped
- Color is assigned from the selected scheme, and rotation is applied based on the orientation setting (horizontal, mixed with periodic vertical rotation, or fully vertical)
The result is a compact, collision-free cloud where word sizes accurately reflect their frequency in your text.
Stage 6: Interactive Display and Export
The cloud renders as a scalable SVG that responds to hover — moving your cursor over any word dims the others and reveals a tooltip with the exact occurrence count. A companion frequency table provides the raw data: rank, word, count, a visual frequency bar, and percentage share, all searchable and scrollable.
When you're ready to use the results elsewhere, export with one click:
- CSV — spreadsheet-ready file with word, count, and percentage columns
- JSON — structured data for programmatic use or API integration
- SVG — vector image of the cloud itself, scalable to any resolution
- Copy — copy the word:list pairs to your clipboard for quick pasting
All processing — tokenization, filtering, counting, layout, and export — happens entirely in your browser. No text is uploaded, stored, or sent to any server.

Frequently asked questions
What is a word frequency cloud?
What is a word frequency cloud?
A word frequency cloud is a visual representation of text data where each word's font size corresponds to how frequently it appears in the source text. Words that occur more often are displayed larger and more prominently, making it easy to identify key themes, recurring topics, and dominant vocabulary at a glance. Unlike a basic word cloud image, our generator also provides exact word counts, percentage shares, a filterable frequency table, and multiple export formats.
How does the word cloud generator work?
How does the word cloud generator work?
The tool processes your text through a six-stage pipeline. First, it tokenizes the input into individual words using Unicode-aware pattern matching that handles multiple languages, contractions, and hyphenated terms. Next, it filters out common stop words (like "the", "and", "is") unless you choose to keep them. It then counts the frequency of each remaining word and sorts them by occurrence. Finally, a spiral placement algorithm positions each word on the canvas, scaling font sizes logarithmically based on frequency, with collision detection to prevent overlaps. Everything runs entirely in your browser.
Is my text data stored or sent to a server?
Is my text data stored or sent to a server?
No. The word frequency cloud generator runs 100% client-side in your browser. Your text is never uploaded, stored, or transmitted to any server. There is no sign-up, no account, and no data collection. This makes it safe to use with confidential documents, proprietary content, or sensitive survey responses.
What are stop words and why are they filtered?
What are stop words and why are they filtered?
Stop words are the most common function words in a language — articles, prepositions, pronouns, and auxiliary verbs like "the", "is", "at", "which", and "on". They appear frequently in almost any text but rarely carry meaningful content. Filtering them ensures your word cloud highlights the most significant and informative words rather than being dominated by filler. You can toggle stop word filtering on or off, view the full list of approximately 280 filtered words, and add your own custom exclusions for domain-specific terms.
Can I analyze bigrams and trigrams (word pairs and triplets)?
Can I analyze bigrams and trigrams (word pairs and triplets)?
Yes. The tool supports n-gram analysis in three modes: unigrams (individual words), bigrams (two-word phrases), and trigrams (three-word phrases). N-gram detection reveals meaningful collocations that single-word counts miss — phrases like "machine learning", "customer service", or "data science". For n-grams, the filter removes phrases that start or end with a stop word, preserving meaningful multi-word terms while discarding noise.
What file formats can I upload?
What file formats can I upload?
You can upload text files in .txt, .md (Markdown), .csv, .json, and .log formats. The tool reads the file content directly in your browser and loads it into the text editor for analysis. Files up to 5 MB are supported. You can also simply paste or type text directly into the input area.
How do I export the word cloud or frequency data?
How do I export the word cloud or frequency data?
The tool offers four export options. Download the frequency data as a CSV file (spreadsheet-ready with word, count, and percentage columns) or as a JSON file (structured data for programmatic use). Export the cloud itself as an SVG vector image that scales to any resolution. Or use the copy button to copy a word:count list to your clipboard for quick pasting into documents or chats. All exports are generated instantly in your browser.
Can I customize the colors and orientation of the word cloud?
Can I customize the colors and orientation of the word cloud?
Yes. The tool includes seven built-in color schemes — Ink, Sunset, Ocean, Forest, Monochrome, Rainbow, and Pastel — and three text orientation modes: Horizontal (all words left-to-right), Mixed (alternating horizontal and vertical for visual variety), and Vertical (all words rotated 90 degrees). You can also adjust the maximum number of words displayed and the maximum font size using sliders.
What is the difference between case-sensitive and case-insensitive analysis?
What is the difference between case-sensitive and case-insensitive analysis?
By default, the tool is case-insensitive, meaning "Apple" and "apple" are counted as the same word. This is useful for general text analysis where capitalization is incidental (e.g. sentence-start capitalization). Enable case-sensitive mode when capitalization is meaningful — for example, when "Apple" (the company) and "apple" (the fruit) appear in the same text and should be tracked separately. Stop word filtering always works case-insensitively regardless of this setting.
How are font sizes determined in the word cloud?
How are font sizes determined in the word cloud?
Font sizes are calculated using a logarithmic scale based on each word's frequency relative to the most and least frequent words. The most frequent word gets the maximum font size, and the least frequent gets the minimum. A logarithmic distribution (rather than linear) prevents smaller-frequency words from becoming unreadably tiny while still clearly showing the hierarchy. You can adjust the maximum font size with a slider; the minimum is fixed at a readable 13px.
Can I exclude specific words from the analysis?
Can I exclude specific words from the analysis?
Yes. In addition to the built-in stop word list, you can enter custom exclusion words or phrases in the "Custom Exclusions" field, separated by commas or new lines. Single-word exclusions remove any token matching that word. Phrase exclusions (multi-word entries) remove exact phrase matches. This is useful for filtering out character names in literary analysis, domain-specific filler in technical text, or any terms that are irrelevant to your analysis.
What is the difference between the cloud view and the table view?
What is the difference between the cloud view and the table view?
The cloud view renders an interactive SVG visualization where word size reflects frequency, with hover-to-highlight and tooltip features. The table view presents the same data in a searchable, scrollable list with rank number, word, exact count, a visual frequency bar, and percentage share. Both views use the same underlying frequency data — toggle between them to switch between visual exploration and precise data inspection. The SVG export is only available in cloud view; CSV, JSON, and copy are available in both.
Does the tool support non-English text?
Does the tool support non-English text?
Yes. The tokenizer uses Unicode property escapes that match letters and numbers across all scripts, including accented Latin characters, Cyrillic, CJK (Chinese, Japanese, Korean), Arabic, and more. However, the built-in stop word list is English-only. For non-English text, you can disable English stop word filtering and use the custom exclusions field to enter stop words in your target language. The frequency counting, cloud layout, and export features work identically regardless of language.
