Text diff
See what changed without sharing either version.
Compare two drafts, configuration fragments, or lists line by line. Added and removed text is rendered safely as text, never interpreted as HTML.
How the comparison works
The tool finds a longest common sequence of complete lines. Matching lines remain neutral, removals appear red, and additions appear green. The work is deliberately capped at 500,000 line-pair cells to keep the tab responsive.
What it does not do
This is a line-oriented review tool rather than a source-control system. It does not understand moved blocks, programming language syntax, or word-level edits inside a changed line.
