Compare two texts and highlight additions and removals by line or word. Inspect spacing, ignore letter case when needed, and save a readable report locally.
Line numbers show original / revised. ↵ marks a line break. Unchanged items show revised text when case is ignored. Reports include your text.
Comparison runs entirely in your browser, without uploads, an account or browser storage. Both inputs stay available while you review changes. User content is rendered as text, including any markup or code.
Additions are marked with plus signs or underlines; removals use minus signs or strike-through. Unmarked text is unchanged under the selected comparison rules. A replacement appears as a removal followed by an addition. Repeated content may allow more than one equally valid alignment.
Word mode compares word segments, punctuation and whitespace. Spacing changes are kept rather than silently ignored. Modern browsers use Unicode word segmentation; older browsers use a simpler rule. Combined results preserve the segment order, while highlights show which side each segment belongs to.
Segments are compared using Unicode lowercase mappings. Spaces, punctuation and line endings still matter. A match with case ignored is reported separately from identical inputs. Unchanged segments display the revised spelling. Locale-specific casing and multi-letter case equivalence are not inferred.
Line mode distinguishes a final line break from no final line break. A visible arrow marks a line break, and a no-line-break label marks a line without one. CRLF and CR endings are normalized to LF, matching browser textarea behavior.
Each side can contain up to 100,000 UTF-16 text units and 2,000 comparison segments. In line mode, segments are lines. In word mode, words, punctuation and whitespace each contribute segments. If a limit is exceeded, your inputs remain unchanged. Compare a smaller section or use line mode.
No. It is a readable TXT comparison with added, removed and unchanged segments. JSON-style escapes make line breaks and tabs visible. It includes your text and is not a unified diff, patch file or word-processing document.
