This text diff comparator analyzes two blocks of text and highlights the differences between them line by line. It shows which lines were added, removed or modified between the original and the updated version. The tool uses a standard diff algorithm to produce accurate comparisons even for large documents. Results are color-coded with green for additions, red for deletions and yellow for modifications. Everything runs in your browser so neither text is ever sent to any server.
This word counter gives you a complete breakdown of any text you paste or type: total words, characters with and without spaces, sentences, paragraphs and lines. It counts composed emojis as a single character, treats non-breaking spaces as word separators, and normalizes line endings so that Windows and Mac text produce the same result. Everything runs in your browser, so your text never leaves your device.
