Text Compare

Review two strings next to each other with inline highlights for changes. Uses the same diff engine as Diff Checker with a side-by-side layout on desktop.

Result

Text A

Paste two texts side by side, then Compare. Differences are highlighted in each panel.

Text B

Paste two texts side by side, then Compare. Differences are highlighted in each panel.

How to compare two texts

  1. Paste Text A and Text B.
  2. Click Compare.
  3. On desktop, panels sit side by side; on mobile they stack.
  4. Copy produces a unified diff with + and - prefixes.

What is Text Compare?

Sometimes you need a quick answer: are these two strings the same? This tool compares two text inputs and highlights every difference — character, line, or block — so you can confirm a copy-paste was exact or spot the single character that broke a test.

Why use DevTilt's Text Compare?

  • Character and line-level difference highlighting
  • Shows match/mismatch summary at the top
  • Handles Unicode and multi-line input
  • Instant comparison on paste

Common use cases

  • Verifying a copied API key matches the original exactly
  • Checking whether two environment variable values are identical
  • Confirming a regenerated config matches the expected output
  • Spotting a hidden whitespace difference in a failing test fixture

FAQ

Same engine, different layout. Text Compare emphasizes side-by-side reading; Diff Checker shows a single unified diff panel.
No. Comparison runs entirely in your browser.
Yes. Inputs and results stack vertically on narrow screens with the same highlighting.
Yes for plain text. Format JSON first with the JSON Formatter if you need comparable structure, then paste both sides here or into Diff Checker.
Trailing spaces, tab vs space indentation, or missing final newlines cause line diffs. Normalize whitespace in your editor or compare smaller excerpts if you need byte-identical confirmation.
