How to use

This tool belongs to the “Text processing” category.

  1. 1Paste the text into the main box; comparison tools give you a left and a right pane.
  2. 2Choose the operation: count, replace, deduplicate, convert between simplified and traditional Chinese, add pinyin, or change case and width.
  3. 3Copy the result back. Most operations update instantly, so you can tweak and re-run.

Your input is processed locally in the browser whenever possible. We do not store it.

Frequently asked questions

Does the word count count characters or words?

Chinese is counted per character; English is reported both per character and per whitespace-separated word.

How long can the text be?

Bounded by the browser and the request size. Tens of thousands of characters are routine; split a whole book into chunks.

Why is the simplified/traditional conversion wrong?

Many characters map one-to-many and need context. The tool uses common mappings — proof-read proper nouns.
