About This Advanced Text Profiler

This page offers a high-value, in-browser text profiling utility built for editors, bloggers, and writing professionals who need more than a simple word count. The profiler calculates technical metrics (syllables, Flesch reading ease), structural measures (sentence length, paragraphs), and lexical measures (unique words, top keywords), helping you tune tone, readability, and SEO relevance.

Why these extra metrics matter

Readability scores give an evidence-based view of how easy your writing is to consume. Lexical diversity and unique word counts indicate whether your text is repetitive or varied — important for SEO and reader engagement. Top keywords and their density help writers ensure a natural use of terms without keyword stuffing.

How to use this tool effectively

1. Paste or type your text and watch the profiler update instantly.
2. Check the Flesch score and average sentence length to adjust for simpler or more formal tone.
3. Use the top keywords list to make sure your target terms appear naturally.
4. Trim long sentences and diversify words to increase readability and reduce bounce.

Privacy & performance

Everything runs in your browser — nothing is sent to our servers. The profiler is lightweight and optimized to handle long documents (thousands of words) with minimal performance impact.
