Word Heatmap
Paste paragraphs to see which words are strongest in each paragraph.
A QUICK WALKTHROUGH
How to use this tool
- Enter at least two paragraphs, with one paragraph on each line.
- Set the number of words to display and the minimum word length.
- Build the heatmap to compare word counts across paragraphs.
Method and limits
Each non-empty line is one paragraph. Words are word-like Intl.Segmenter segments for the page language; punctuation and spaces are excluded. Chinese and Japanese boundaries depend on browser language data. Counts are case-insensitive after NFC normalization; no stemming or stop-word removal. Text is limited to 50,000 UTF-16 code units, 60 paragraphs and 2,000 unique words.
