Sentence Counter

The Sentence Counter goes beyond a simple word count by giving you a full textual analysis: sentence count, word count, syllable count, estimated reading time, and a keyword frequency breakdown. It's a comprehensive writing metrics tool in one place.

Reading time estimates help you set expectations for your audience — blog posts, newsletters, and documentation all benefit from knowing whether readers are committing 2 minutes or 10. Syllable counts and keyword frequency are useful for readability scoring and SEO analysis, helping you assess whether your content is appropriately dense or repetitive.

Keyword frequency is calculated by counting how often each unique word appears (excluding common stop words), so you can spot overused terms at a glance. All analysis runs locally in your browser with no data sent to any server.
