Text Tools

Text tools handle the small chores of writing and editing: counting against a limit, converting between writing systems, finding out exactly what changed between two drafts. Everything on this page runs in your browser — what you paste is processed locally and never sent anywhere, so drafts, contracts and private notes stay on your own machine.

Word counter counts words, characters, sentences and paragraphs the way real text needs — Chinese, Japanese and Korean are counted by character, mixed paragraphs work, and reading time is estimated per language. Simplified ⇄ Traditional is built on OpenCC, the same open-source engine Wikipedia uses for its Chinese variants, and handles regional vocabulary (Taiwan, Hong Kong) as well as the character mapping.

Text compare shows every difference between two texts or files, side by side or as a unified diff with word-level highlighting, and writes out a standard patch you can paste anywhere. It uses the patience and Myers algorithms that git itself uses, so the result reads the way a code review does. Each tool page explains what it counts or converts and where it is normally used.
