A simple find-and-replace can't swap two words with each other in one step, since replacing the first word with the second would then get caught by the second replacement pass, undoing the swap. This tool handles that properly using a temporary placeholder internally.
Enter the two words you want to swap, and every occurrence of each is replaced with the other throughout your text, correctly avoiding the double-replacement problem a naive approach would hit.
This is useful for correcting a systematic naming mix-up throughout a document, swapping placeholder names in a template, or any text editing task where two terms need to trade places everywhere they appear.

Frequently asked questions
Is this case-sensitive?
Yes, by default the swap matches exact case; "Cat" and "cat" are treated as different strings unless they're both entered exactly as they appear.
What happens if one word is part of another, like 'cat' inside 'category'?
This tool matches whole words only by default, so 'category' won't be affected by a swap targeting 'cat'.
