New Tool: Text Diff Checker
Spot Every Change Between Two Texts
Comparing two versions of the same text by eye is slow and error-prone. The new Text Diff Checker lines up an original and a modified version and highlights exactly what changed — added lines, removed lines, and the precise characters that differ within a line.
Just Paste and Compare
There is no upload step or "Compare" button to hunt for. The tool opens with two editable panes — Original on one side, Modified on the other. Clear the sample text, paste your two versions, and the diff recomputes live as you type. Because both sides stay editable, you can fix a typo on the spot and watch the comparison update instantly.
Side-by-Side or Inline
Switch between two ways of reading the diff:
- Side-by-side — the original and modified texts sit in parallel columns, ideal for a quick visual scan.
- Inline — a single unified view where removed lines sit directly above the lines that replaced them, closer to a classic patch.
Use Prev and Next to jump straight from one change to the next instead of scrolling, and Swap to flip which side is the original.
Tuned for Real Comparisons
A few options keep the diff focused on what actually matters:
- Ignore whitespace — hide changes that are only differences in leading or trailing whitespace, so reformatting noise does not drown out real edits.
- Syntax highlighting — pick a language so both sides are colored as code, making structural changes easier to follow.
- Word wrap — toggle wrapping for long lines instead of scrolling horizontally.
Who It's For
- Developers reviewing edits to config files, snippets, or generated output
- Writers and editors comparing two drafts of a document
- Anyone who needs to know what changed between two blocks of text
Privacy First
