Paste both versions into a browser-based text diff tool and it highlights every added, removed and changed line side by side. The comparison runs entirely on your device, which matters because the things people diff, contracts, configs, code and prompts, are usually exactly the things they should not upload.
Two versions of a config, a contract clause, an email draft or a generated file can look identical while hiding one changed line. A diff algorithm compares them line by line and pinpoints the exact insertions and deletions, the same way git shows changes, so you review only what differs instead of proofreading everything twice.
Think about what actually gets diffed: production configuration before and after an incident, legal wording between contract drafts, two versions of internal documentation. A client-side diff computes everything in your browser, so neither version of the text is transmitted or stored anywhere.
No. Both texts stay in your browser and the comparison runs locally.
The diff is line-based, highlighting added and removed lines so changed lines stand out clearly.
No account limit. Very large documents are bounded only by your browser memory.
