Is it safe to paste confidential NDA clauses into this diff tool?

Yes. Unlike public diff websites that log comparisons to databases or train third-party AI models on your input, our tool runs strictly in client-side RAM with zero network sockets open.

What algorithm does this diff engine use?

It uses the Eugene Myers O(ND) difference algorithm, the same gold standard used by Git and Unix diff utilities to calculate minimal edit paths with sub-millisecond latency.

Why Online Diff Tools Create Catastrophic NDA Liability

When reviewing legal agreements, commercial leases, or proprietary algorithms, pasting revisions into free online "diff checkers" transmits your trade secrets to third-party web servers. Many of these free sites log payloads for advertising profiling or training generative models. Rehan Quant Lab difference workstations guarantee that not a single word ever leaves your machine.

Mathematical Myers Algorithm Foundations

The Myers difference algorithm models file changes as an edit graph search problem. By traversing diagonal snakes along identical line matches, it computes the Shortest Edit Script (SES) with minimal CPU instruction cycles. It handles multi-line insertions and deletions with zero lag in pure client-side execution.
