Character / Word / Line Counter
Real-time character, word, sentence, paragraph and line count. Includes meters for SEO meta title (60), meta description (160), tweet (280). Reading time estimate.
Common limits
When to use it
- SEO meta: title ≤ 60 chars, description ≤ 160 chars — Google truncates beyond.
- Social posts: X/Twitter 280, LinkedIn 3000.
- Articles: reading time based on 250 wpm (silent) and 150 wpm (spoken).
- Academic: word count for essays and abstracts.
How is this different from Token Counter?
An LLM token ≠ a word. ~1 English token ≈ 0.75 words. If you care about API cost, use the Token Counter. If you just need length, use this one.
Who this is for
Content writers, editors, SEO specialists, devs handling text/markdown — URL slugs, char counts, regex testing, SQL formatting.
