Word Frequency Analyzer
Free word frequency analysis software — extract unique words, count occurrences, and filter out vocabulary you already know. Runs entirely in your browser.
Word-Translation Merger
Paste words in the left column and translations in the right, then copy the merged result in word;translation format.
How to Analyze Word Frequency
- Paste your text — enter or paste any text into the input area. It works with any language.
- View the frequency table — click "Analyze" to see every word ranked by how often it appears, with exact counts.
- Filter known words — add words you already know to the exclusion list. The "New words" table shows only unfamiliar vocabulary.
- Export or merge — copy the results table, or use the Word-Translation Merger to create flashcard-ready word lists.

Frequently Asked Questions
Is Word Frequency Analyzer free?
Yes, it's completely free with no limits on usage.
Is my text sent to a server?
No. All text analysis happens locally in your browser. Your data never leaves your device.
How does the exclusion list work?
Enter words you already know (separated by spaces, commas, or new lines). Those words will be filtered out from the "New words" table, so you only see unfamiliar vocabulary.
What is the merger section for?
It lets you paste a list of words in one column and their translations in another, then merge them into a "word;translation" format you can copy and use in flashcard apps.
How does this compare to desktop word frequency analysis software?
This tool provides the same core analysis — word counting, frequency ranking, and filtering — but runs instantly in your browser with no download or installation. Your text stays private since nothing is sent to a server.
Can I use this for SEO keyword research?
Yes. Paste any webpage content to see which words and phrases appear most often. This helps identify keyword density and discover overused or missing terms in your content.
