- What counts as a word?
- Any run of characters between spaces or line breaks. Hyphenated forms like 'well-known' count as one word, which matches how most word processors count.
- Do emoji and accented letters count as one character?
- Yes. Counting is Unicode-aware, so é or an emoji is one character even though it may occupy several bytes.
- What are common length limits?
- An X/Twitter post allows 280 characters, an SMS 160, a meta description around 155 to 160, and typical college essays are measured in words, not characters.
- How accurate is the sentence count?
- Sentences are split on . ! and ? followed by a space. Abbreviations like 'e.g.' can add a sentence to the count, so treat it as a close estimate.
