Edit a short draft in three steps

Start with NASA report: café as a heading and a short paragraph beneath it. Each tool answers a different question; moving between them does not automatically transfer your text.

Does the draft fit the submission limit?Word & Character CounterCompare the destination's counting rule; emoji and whitespace can be counted differently.
Which capitalization or identifier style is needed?Text Case ConverterReview acronyms and names. Title Case produces Nasa Report: Café, changing NASA.
What changed between drafts?Text Difference CheckerRead added and removed lines together. A moved line may appear as two changes.

What the numbers and edits mean

The counter uses whitespace for word boundaries and UTF-16 units for characters. Its 200-word-per-minute estimate is for rough silent reading, not spoken timing or comprehension. Case conversion applies character rules, not editorial judgment. The difference checker compares plain text by line and ignores fonts and page layout. Keep the original and review the final text where it will be published.

For data transformations rather than prose editing, the developer workflow connects CSV, JSON, encoding, and exact-input comparisons.

Check Unicode and moved lines

你好世界 has four UTF-16 units but is one whitespace-delimited token here. This is not a linguistic word count. Moving gamma from the end of alpha / beta / gamma to the start appears as a removal and addition; compare the complete texts before accepting an edit.

Repeat the Unicode counting experiment

The recorded word-counter experiment compares ordinary text, combining accents, emoji, Chinese text, and invisible separators. Download its fixtures and compare the actual UTF-16 character count with your destination's rule; a visible symbol is not always one character unit.
