About this
Pattern-based: handles articles, demonstratives, and verb agreement
(the women are ↔ the woman is). Includes
irregular plurals (women, mice, children, leaves, …).
Swap word pairs
About this
Swaps left ↔ right (case preserved). Word boundaries
prevent matches inside words like leftover.
Tip: select text to apply a transformation to only that portion — no selection = whole text.
Chain transformations freely; Undo (or Ctrl/Cmd‑Z) steps back through up to 50 versions.
