Lexical Density Analyzer & Text Complexity Tool

Gauge the complexity and readability of your writing with our Lexical Density Analyzer. This tool measures the proportion of meaningful "content words" (nouns, adjectives, verbs) to grammatical "functional words" (prepositions, conjunctions). It provides a clear score and visual feedback to help you understand if your text is conversational, academic, or somewhere in between. It's an invaluable resource for writers, educators, and content strategists.

How It Works

Our analyzer provides an instant, in-depth look at the structure of your vocabulary. It breaks down your text and visualizes the results in an easy-to-understand dashboard.

  1. Enter Your Text: Paste your content into the editor. The analysis runs automatically.
  2. Check the Density Score: The dynamic gauge instantly shows your text's lexical density, complete with a descriptive label of its complexity level.
  3. Explore the Breakdown: Review the detailed word counts and the ranked lists of every lexical and functional word found in your text.

Key Features

  • Dynamic Lexical Density Gauge: A prominent circular gauge provides your text's density score. The color and label update in real-time to reflect the complexity, ranging from "Highly Conversational" to "Highly Academic / Technical".
  • Comprehensive Word Analysis:
    • Lexical Words: The "content" or "meaningful" words that carry the primary information (e.g., 'principle', 'analysis', 'useful').
    • Functional Words: The grammatical "glue" words that structure sentences (e.g., 'the', 'is', 'of', 'and').
  • Detailed Statistics: See precise counts for Total Words, Lexical Words, and Functional Words, giving you a clear overview of your text's composition.
  • Ranked Word Lists: View two separate lists containing every unique lexical and functional word used, sorted by frequency. This helps you identify overused terms and understand your vocabulary choices.
  • Interactive Lexical Highlighting: With a single click, you can highlight all the lexical (content) words directly in the text. This provides an excellent visual aid for seeing the "scaffolding" of your writing.
  • Real-Time & Responsive: The entire analysis updates live as you type, with a smart debounce delay to ensure a smooth and performant experience.

  3. Step 3: Examine the Word Lists
    Review the sorted lists to see which content words and grammatical words you rely on most.
