Counting words sounds unambiguous and is not. Two tools will give different numbers for the same paragraph, and the difference is never a bug; it is a different definition. Knowing which definition you are being held to is the only thing that matters.
The disagreements are specific. A hyphenated compound like state-of-the-art is one word or four depending on whether the counter splits on hyphens. An em dash with no spaces around it can join two words into one token. Numbers, dates and currency amounts may count as words or be excluded. A URL is one long token to a splitter and several words to a human. Contractions are one word everywhere, but an apostrophe from a different character set can break the token in two.
Character counts have their own trap, and it is the one that catches people submitting to a form with a limit. A character count can mean Unicode code points, or bytes, or what a naive length function returns. For plain English they agree. For accented characters, emoji and non-Latin scripts they do not, and an emoji made of several joined code points can count as one character to a reader and four or more to the field validating it. A text that fits in your editor is then rejected by the form with no visible reason.
Reading time is an estimate built on an assumed speed, usually somewhere between 200 and 250 words a minute for ordinary prose. It is useful as a rough signal and should not be treated as a measurement: technical material with code in it reads far slower, and a list reads faster than a paragraph of the same length.
For anything with a hard limit, the only reliable approach is to check in the system that enforces it. A publisher's word count, a university's, and a job portal's may each differ from yours, and the one that decides is theirs. Use a counter to get close, then confirm where it counts.
The counting happens in your browser tab, so the text never leaves the device. That is the point when the thing being counted is a cover letter, a dissertation chapter or a piece of unpublished client work.
