Text Difference Checker & Comparison Tool

Instantly compare two versions of a text to find every addition, deletion, and modification with our powerful and intuitive Diff Checker. Whether you're tracking changes in a document, reviewing code, or comparing notes, this tool provides a clear, color-coded visualization of the differences. You can compare text line-by-line or word-by-word to get the perfect level of detail.

How It Works

Our comparison tool is designed for immediate feedback. The analysis runs automatically as you type, providing a live view of the differences between the two texts.

  1. Enter Your Texts: Paste your original text into the left panel and the modified version into the right panel.
  2. Choose a Comparison Mode: Select whether to compare the texts by "Line" or by "Word" from the dropdown menu.
  3. Analyze the Diff: The results panel immediately displays a detailed, color-coded report highlighting all the changes.

Key Features

  • Dual Comparison Modes:
    • Compare by Line: Ideal for structured text, lists, or code. It highlights entire lines that have been added, removed, or changed.
    • Compare by Word: Perfect for prose and paragraphs. It pinpoints individual words that have been changed within a line.
  • Real-Time Analysis: The comparison runs automatically as you type in either text box, with a smart delay to ensure a smooth and responsive experience without slowing down your workflow.
  • Clear, Color-Coded Visualization:
    • Additions: New lines or words are clearly marked in green.
    • Deletions: Removed content is marked in red.
    • Unchanged: Lines that are identical between both versions are shown with a neutral background for easy scanning.
  • Comprehensive Statistics:
    • Per-Panel Stats: Get live character and word counts for both the original and modified text panels.
    • Difference Summary: A dedicated stats bar for the results shows the exact number of additions and deletions found.
  • Convenient User Actions:
    • Copy Diff Report: A one-click button to copy a plain-text version of the detailed difference report to your clipboard.
    • Clear All: Instantly reset both text panels and the results to start a new comparison.
