Text Compare: Diff & Merge

Find every difference between two texts or compatible text files, review each change and build a clean merged version without uploading your content. • Compare by line, word or character • Detect added, removed and modified content • Use unified, side-by-side or changes-only views • Jump between changes and search inside the result • Keep the original or accept the revision for each block • Edit the final merged text with undo and redo • Ignore case, repeated spaces, blank lines, accents or punctuation • Use optimized profiles for normal text, lists, code and translations • Read UTF-8, UTF-16 LE/BE and Latin-1 files • Export TXT, Markdown, HTML, PDF and unified patches • Share results without a watermark • Optional metadata-only history with search and favorites • Light, dark and system themes • Seven interface languages Comparison, merging and exports run locally. PrismaLab Studio does not upload your text. The app is fully functional without an account and contains banner and occasional interstitial advertising.

A new document workspace: aligned original and revised text, differences highlighted inside each line, search, change navigation and merge choices. Keep edits when rotating, review manual changes safely, and work with large documents in sections. Improved PDF layout and file sharing.
