Text Diff
Compare two texts side by side; optionally copy a git-style patch for your workflow.
Treat the left box as the “old” version and the right as the “new”. The diff below updates as you type; everything stays in your browser.
Removals lean red on the left, additions green on the right; unchanged lines appear in both columns.
Diff output
Fill fields
Move text between the two boxes; comparing does not change them.
Export
Patch is for git or other tools; right-hand text copies as plain text.
How to use
Paste large YAML, env files, or multi-thousand-line code into A (left) and B (right). Git diff view shows `@@` hunks with `+` / `−` lines and color cues. Side-by-side mode uses row numbers, − / + markers, and virtualized scrolling for smooth performance.
Migrate & sync: replace B with A or A with B, swap sides, or copy the unified patch / text B to the clipboard.
Toggle “ignore leading/trailing space” to downplay whitespace-only edits. All diffing stays in your browser.
