compare-text.onlineAbout Compare Text
A free online diff studio that compares two pastes or dropped UTF-8 files - prose, source code, YAML, SQL, logs - in split or unified view. Changed lines get word-level highlighting, with options to ignore whitespace and case, a similarity score, change counts and J/K keyboard navigation between edits. Snapshots can be saved to browser history and exported as an HTML report, unified patch or Markdown summary. Comparison runs locally, and content is only sent to a server if you opt into AI analysis. Sister pages cover PDF, image, CSV and JSON diffs; the interface is available in seven languages.
