Text Diff

Online Text Diff — Compare Two Texts in Real Time

PlainRaw's text diff tool highlights every change between two pieces of text as you type. Paste an original on the left, paste the revision on the right, and you'll see additions, removals, and character-level edits the moment they happen.

How it works

The diff runs entirely in your browser using the same algorithm family as git diff. Inserted text is shown in green, removed text in red, and unchanged context stays neutral so the meaningful changes stand out. There's no upload, no sign-up, and no length limit beyond what fits in your browser tab.

Common use cases

  • Reviewing prose edits: compare a draft against its rewrite to see exactly what a copy editor or collaborator changed.
  • Config and YAML comparison: spot drift between two environment files without trusting your eyes line-by-line.
  • API payload changes: format with the JSON Editor first, then drop both versions in here to find the new or removed fields.
  • Translation and localisation review: verify only the strings you expected to change actually changed.
  • Snippet history: compare two revisions of a saved Markdown snippet without leaving the browser.

Because the comparison is character-level, even a single typo or a stray whitespace shows up — useful when you need to be sure two strings really are identical.
