About Flashcards
What this tool does
Text and data tools count words, characters, sentences, and paragraphs, convert between upper/lower/title case, compare two texts side by side, and transform text in dozens of ways: reverse, sort, deduplicate, wrap, or pad.
Why use this tool
Writers need word counts for assignments, developers need text manipulation for data cleaning, and marketers need character limits for meta descriptions and ad copy. These tools provide instant answers without spreadsheets or scripts.
How it works
The tool parses your input string using JavaScript string methods and regular expressions, applies the selected transformation, and displays the result alongside useful statistics. No data is sent anywhere.
Pro tip
The word counter respects CJK characters and counts them individually, which is useful for content localized in Chinese, Japanese, or Korean where word boundaries differ from Latin scripts.
