Text Diff Comparer

Compare paragraphs, source code, config files, or raw logs. Highlight additions, deletions, and specific modified words. Everything runs in your browser sandbox — zero data leaves your machine.

🔒 100% Local Processing

Diffing runs completely in memory on your browser thread. No fetch / XHR calls are issued. Toggle airplane mode to verify the emerald glowing badge — proof JsGo is technically incapable of seeing your documents.
