Our Story
About Us
WordCounter Tools is a completely free, privacy-first online text analysis suite. We believe every writer, student, and content creator deserves access to precise, instant text analysis tools — without sacrificing privacy.
All text processing — word counting, sentence analysis, readability scoring, keyword density, AI token estimation — happens entirely in your browser using client-side JavaScript. Your text never leaves your device and is never transmitted to any server. This is our design philosophy: tools should run locally, and privacy protection should never be an optional feature.
