Text Diff Checker - Compare Text Online
Compare two text blocks by character, word, or line and highlight additions and removals without uploading your content.
TEXT DIFFERENCE CHECKER
Compare two blocks of text and instantly see what has changed. Perfect for code, documents, and lists.
Our tool highlights additions in green and removals in red, making it easy to spot even the smallest edits.
Paste the earlier text on the left and the revised text on the right, then choose character mode for small edits, word mode for prose, or line mode for code, lists, and configuration. Run the comparison to review inserted and removed segments in one result.
This is a literal plain-text comparison, not a semantic review or merge tool. Reworded sentences remain different even when their meaning is similar, and whitespace or punctuation can affect the result depending on the selected mode. Rich-text formatting, comments, tracked changes, and document layout are not preserved when text is pasted into the fields.
Frequently Asked Questions
