About Word Frequency
Word Frequency is a high-performance web utility built to analyze the frequency and density of words in your text in real-time. Discover most repeated keywords, filter out stop-words, and export the analysis instantly and securely. Because it is designed with a local-first architecture, all processing occurs directly in your browser's memory using client-side JavaScript. This ensures that your files, code, or private text inputs are never uploaded to any external server or tracked by third-party analytics.
Whether you are formatting source code, cleaning text files, converting file structures, or running diagnostics, running these processes locally in your browser memory sandbox eliminates network latency and protects your data privacy.
