Free Online Word Counter & Keyword Density Analysis Tool

Overview

A clean, professional, and high-performance browser-based text analysis tool. This application provides real-time feedback on content length, readability, and SEO performance metrics. Designed for content creators, marketers, and students, it offers a distraction-free environment for rapid text analysis.

Core Features

• Real-time Statistics: Instant calculation of words, characters (with and without spaces), sentences, and paragraphs as the user types.
• Keyword Density Analysis: A dedicated table that ranks words by frequency, automatically filtering out common stop words to identify SEO opportunities.
• Reading Time Estimator: Calculated based on a standard reading speed of 200 words per minute.
• Detailed Text Metrics: Average word length and sentence length indicators to help gauge readability scores.
• Clipboard Interaction: Quick "Copy to Clipboard" and "Clear Text" actions for seamless workflow management.

UI/UX Specification

• Layout:
  • Header: Sticky top section with a clean title and concise tagline.
  • Main Input: A large, high-contrast, borderless text area with soft shadow effects and generous padding.
  • Results Dashboard: A grid layout appearing below the input area featuring stat cards (Word Count, Reading Time, etc.).
  • Analysis Table: A clean, striped table underneath the stat cards displaying Keyword, Count, and Density %.
• Aesthetics:
  • Palette: A professional light-mode scheme. Backgrounds in soft whites (#F9FAFB), text in charcoal grays (#1F2937), and a primary accent color in soft indigo (#4F46E5) for call-to-action elements.
  • Typography: Clean, sans-serif font stack (Inter or System UI) for maximum readability.
  • Animations: Subtle CSS transitions on card hover states and list entry animations for the keyword table.

Technical Implementation Guidelines

• Architecture: Single-file HTML/CSS/JS. No build step required.
• Performance: All logic is handled via efficient JavaScript functions. Keyword extraction uses regex for speed.
• Constraint Compliance:
  • No Storage: No use of localStorage or cookies. Data resides only in the application's RAM during the session.
  • No Popups: All user notifications (e.g., "Copied to clipboard") must use custom HTML/CSS snackbar components inside the page DOM.
  • Responsiveness: Use Flexbox/Grid for the layout to ensure the input area and results table stack gracefully on mobile devices.
  • Browser Compatibility: Strict adherence to modern web standards; no proprietary plugins or server-side dependencies.
