Text Diff Checker is now live on Tools.Town — a tool that compares two text blocks and shows a color-coded diff: green for added lines, red for removed lines, and yellow for changed lines, with inline character-level highlighting for modified content.
Compare two versions of a document, config file, or code snippet to see exactly what changed.
What Does It Do?
Line Diff
Color-coded line-by-line comparison — green for additions, red for deletions, yellow for modifications.
Inline Changes
Within changed lines, the exact characters that were added or removed are highlighted — no guessing.
Unified View
Switch between side-by-side and unified (inline) diff views depending on your preference.
Text Diff uses the Myers diff algorithm — the same algorithm behind Git’s diff output.
How It Works
Paste original
Paste the original text into the left panel.
Paste modified
Paste the modified text into the right panel.
Read the diff
The diff appears immediately — green adds, red deletes, yellow changes. Switch views as needed.
Why We Built It
Contract revisions, document edits, config changes, and code reviews all need a quick way to see exactly what changed between two versions. Git handles this for tracked files. Text Diff Checker handles it for everything else — pastes, clipboard content, generated text, and any document you don’t have under version control.
