Does it count common words like "the" and "a" by default?

You can typically filter these out to focus on more meaningful, less common words, since function words naturally dominate frequency counts without being informative.

Is this the same calculation as the SEO Keyword Density Checker?

They calculate similar underlying frequency data — this tool is framed more generally for any text analysis, while the SEO tool is framed specifically around content optimization.

Can I check word frequency in a very long document?

Yes, it handles longer texts without issue, which is exactly where manual counting becomes impractical anyway.

Does Word Frequency Counter upload my files to a server?

No. Word Frequency Counter runs entirely in your browser using on-device processing, your files never leave your device.

About this tool

Finding the most repeated words in a piece of writing — for checking keyword density, spotting overused words in your own writing, or analyzing a text — means counting occurrences of every word, which isn't practical to do by hand in anything longer than a short paragraph. This tool finds the most repeated words and checks keyword density in a text automatically, surfacing patterns you'd otherwise have to count manually.
