Compare Text helps writers, editors, students, and developers review changes between two versions of copy, configs, or notes. Paste an original and a modified version, pick line, word, or character precision, and read a clear side-by-side or unified diff with accessible +, −, and ~ markers — all processed locally in your browser.
.txt files or import from a URL if needed.Best for articles, changelogs, and configs. Inserts and deletions stay aligned; modified lines show inline word highlights on both sides.
Treats the full text as a sequence of words — ideal when paragraphs were rewritten but line breaks differ.
Uses Unicode grapheme-safe splitting so emoji, accents, and combining marks are never broken mid-character.
Side-by-side (split) view lines up Original and Modified columns with line numbers — easiest for scanning parallel edits on wide screens. On narrow screens the modified column stacks under each row. Unified view prints a classic + / − / stream like version-control diffs, handy for copying into tickets or email. Both views use the same underlying comparison; toggling views never changes the counts.
After reviewing changes, try Find and Replace Text to apply batch edits, Sort Lines to reorder lists, Remove Duplicate Lines, Remove Empty Lines, Word Counter, and Character Counter.
