Glossary
Concepts you'll see while using this tool
Short, source-backed definitions of the terms behind Text Summarizer.
- Word countSource ↗
- The total number of word tokens in a piece of text, typically derived by splitting on whitespace and punctuation. Common in publishing, education, and SEO as a length metric.
- Character countSource ↗
- The total number of code points (or graphemes, in Unicode-aware tools) in a text. Platforms like SMS and Twitter enforce limits in characters, not words.
- UnicodeSource ↗
- The international standard that assigns a unique number to every character in every script. Modern text tools use Unicode so counts work consistently across languages and emoji.
- Intl.SegmenterSource ↗
- A JavaScript API that splits text into Unicode graphemes, words, and sentences using the same locale rules browsers use natively. Tools that use it count complex scripts correctly.
- Text miningSource ↗
- The process of deriving structured information from natural-language text, including counts, frequencies, sentiment, and entities. Web-based counters and analysers are simple text-mining tools.
How we count, and when this page was checked
Word and character counts on this page use the browser's Unicode-aware Intl.Segmenter API, so figures match the underlying graphemes rather than guessing from byte length. Reading-time estimates default to 238 wpm (Brysbaert, 2019). Last editorial review: 2026-05-18.
