About these tools
The privacy point is easy to dismiss for text tools and should not be. The text people paste into a diff checker or a word counter is very often a draft contract, an internal email, an unpublished article or a block of production source code. A tool that posts that to a server to count its words has taken a copy of something confidential to do arithmetic that a browser can do in a millisecond.
A note on counting, since it is the most common source of confusion: different tools disagree about words because they disagree about what a word is. Hyphenated compounds, numbers, contractions and em dashes are all edge cases, and a target of "500 words" set by one system will not match another exactly. Character counts are less ambiguous, but bytes and characters diverge the moment your text contains an emoji or an accented letter — which is why the character counter reports both.
Frequently asked questions
No. Every one of these tools computes its result in the page as you type. Nothing is transmitted and nothing is retained after you close the tab, which is why pasting confidential drafts or source code here is safe.
Because word counting has no single definition. Tools differ on hyphenated compounds, standalone numbers, contractions and text around punctuation. Expect small differences between any two counters; if a hard limit matters, count in the system that will enforce it.
Comfortably into the megabytes. The work is done by your own processor with no round trip, so the practical limit is how much text your browser will hold in a text area rather than any cap set here.
