Tracking whether a revision pass made a piece of writing longer or shorter — and by exactly how much — is a quick sanity check when editing toward a specific target length, especially across multiple rounds of edits.
This tool counts the words in your original and revised drafts side by side and calculates the exact difference, clearly showing whether the revision added or removed words and how many.
This is useful for writers tracking whether their editing pass is trimming a piece down toward a word limit or unintentionally padding it out, without needing to manually run two separate word counts and subtract by hand.

This kind of task shows up constantly in everyday writing, coding, design, and admin work, which is exactly why a dedicated, focused tool saves so much back-and-forth.
A tool that does one job well, without a cluttered interface or unrelated features competing for attention, tends to be faster to use than a heavier all-in-one app.
If you find yourself needing this often, keeping this page open in a tab is usually faster than digging through a bigger software suite's menus.

Frequently asked questions
Does this show which specific words changed, or just the count difference?
This shows only the numeric word count difference; for a detailed breakdown of exactly which words were added or changed, use a dedicated word-level text diff tool instead.
Is a negative difference shown, or just the absolute value?
The difference is shown as a signed number, so you can clearly see whether the revision added words (positive) or removed words (negative).
