Free Word Frequency Analyzer

A free word frequency analyzer counts how many times each word appears in your text and ranks them from most to least frequent, with counts and percentages of total words. Toggle ignore common stop words, case sensitivity, and minimum word length, then view a simple top-10 bar chart — all in your browser with no signup.

Paste any block of text and instantly see how often each word appears. Results show a ranked list (most frequent first) with count and percentage of total words, plus a horizontal bar chart of the top 10. Options let you ignore common stop words (the, a, is, and similar), treat “Word” and “word” separately, or filter by minimum word length. Pure client-side JavaScript — nothing is uploaded.

Options

Stop words are common fillers like “the”, “a”, and “is”. Percentages use filtered word totals.

Paste a paragraph to see a ranked word list with counts, percentages, and a top-10 bar chart. Toggle stop words, case sensitivity, and minimum length to refine results.

Runs 100% in your browser. Your data never leaves your device.

Plain JavaScript tokenization splits text into letter/number words (including internal apostrophes), optionally lowercases tokens, drops English stop words, filters by minimum length, then aggregates counts in a Map and sorts by frequency. Percentages use the filtered word total. The top-10 chart is CSS flex bars — no chart libraries and no server calls.

How to Use Word Frequency Analyzer

  1. Paste or type your text in the input box
  2. Optionally ignore stop words, turn on case sensitivity, or set a minimum word length
  3. Read the ranked list with counts and percentages
  4. Scan the top-10 horizontal bar chart for a quick visual overview

When Would You Use This?

SEO writers paste a draft to spot overused keywords after filtering stop words — then tighten wording before publishing.

Students checking essays for repetitive vocabulary sort by frequency and raise the minimum length to focus on content words instead of “the” and “and.”

Editors comparing two versions of a post can open this beside the Word Counter and Readability Score Checker to balance length, ease of reading, and word variety in one workflow.

Frequently Asked Questions

Is this word frequency analyzer free to use?
Yes, completely free. No signup, no login, no payment ever.
Do I need to create an account?
No account needed. Open the tool, paste your text, and see frequencies immediately.
Is my data safe?
Everything runs in your browser. Your text is never uploaded to our servers.
What are stop words?
Stop words are common filler words such as “the”, “a”, “is”, “and”, and “of.” Ignoring them highlights content words that usually matter more for SEO and editing.
How are percentages calculated?
Each word’s percentage is its count divided by the total number of words after your filters (stop words, case, and minimum length). Together, percentages for the filtered list add up to 100%.
Does case sensitivity change the results?
When case sensitivity is off (default), “Apple” and “apple” count as the same word. When it is on, they are counted separately.
Does this work offline?
Yes. Once the page has loaded, all frequency counting works fully offline.
