FAQ
What are stopwords?+
Common particles, articles, and conjunctions like 'the', 'is', 'and' — words without much meaning. Filtering them leaves only meaningful words.
Does it handle Korean and English well?+
Yes. Korean splits on spaces plus particle separation; English splits on spaces and punctuation.
Difference between character and word frequency?+
Character frequency counts at the letter or syllable level; word frequency counts at the meaning level. Choose based on purpose.
How do I use the results?+
(1) Check for overused words in your writing, (2) SEO keyword density, (3) extract key concepts from papers, (4) visualize with the Word Cloud tool.
Does my text leave the browser?+

Is it fast on long text?+
Tens of thousands of characters process instantly. Book-length text (100K+ chars) works without issue.
