Free, privacy-first text toolkit for writers and developers. Five tools: Word Counter (with reading time), Character Counter (with Twitter/Instagram/LinkedIn presets), Case Converter (10 modes — camelCase, snake_case, kebab-case, etc.), Text Reverser, and Duplicate Remover. Everything runs client-side in your browser. Your text never leaves your device. No account, no ads, no premium tier. I built TextKit because every word counter I found was buried in ads or wanted my email first.
