Use it whenever you write to a length spec — a 300-word LinkedIn post, an 800-word blog post, a 1500-word essay, a tweet under 280 characters. Estimating by eye is unreliable. The reading-time figure is also useful as a 'time to read' annotation on blog posts. Alternative: most editors show a word count somewhere; this tool wins for keyword density and readability scoring.
