Text diff checker

Aligned comparison: line 1 vs line 1—great for quick drafts, not merges.

Paste two versions to spot changed, removed, and added lines at a glance. For structural merges use git or a dedicated diff tool; this page is for fast sanity checks.

How it works

Lines are compared by position: line 1 to line 1, and so on.

Insertions in the middle shift lines; this is not a full Myers diff. Use for quick checks.

Limitations

For large merges use a dedicated diff or version control tool.
