Compare two text blocks side-by-side with line-level highlighting.
Paste two blocks of text above to see a line-level diff.
CipherForces Text Diff takes two text blocks — JSON configs, logs, email drafts, contract revisions, code snippets — and shows you exactly what changed line by line. Additions in green, deletions in red, context preserved. Toggle between side-by-side and unified (GitHub-style) views.
Privacy: Both text blocks are diffed in your browser. Paste sensitive content (contracts, logs, API keys) without worry — nothing reaches any server.
