Word Splitter

What is Word Splitter?
Word-level analysis starts with one word per line. Doing it manually on an article takes hours for what should be one click.
Paste your text and get a clean per-word list back.
If you're running frequency analysis, you skip writing a tokenizer. If you're building vocabulary lists, you check content against age-band words. If you're prepping NLP corpora, you produce token streams instantly.

Common questions
How are word boundaries detected?
Whitespace and most punctuation. Hyphens often join compounds.
Tip: Strip punctuation first for stricter splitting.
Are hyphenated words kept together?
By default yes. Toggle to split on hyphens for stricter tokens.
Tip: Data scientists usually split, linguists usually keep.
Does it lowercase words?
No, case is preserved. Run Lowercase first for frequency analysis.
Tip: Lowercase first to merge 'Apple' and 'apple' counts.
Are contractions split?
'Don't' stays as one word by default.
Tip: Use a contraction expander first for 'do not' as two words.
