About

In digital communication, brevity is often enforced by hard technical constraints. A tweet cannot exceed 280 characters; a Google meta description truncates after 160 pixels (approx. 155 characters). For SEO specialists, staying within these bounds determines whether a click-through rate soars or plummets. For students, meeting minimum word counts is the difference between a pass and a fail.

This tool goes beyond simple counting. It analyzes the texture of your writing by calculating keyword density (preventing keyword stuffing penalties) and estimating reading time based on the standard average of 200 words per minute. It acts as a dashboard for content optimization, ensuring your text is not only the right length but also semantically balanced.

Formulas

Keyword density D for a specific term t is calculated as:

D_t = count(t)TotalWords × 100

Estimated Reading Time (min) is derived from standard speech rates:

Time ≈ WordCount200
