How many AI tokens are in 1,000 Chinese characters?

In modern multilingual tokenizers (GPT-4o, Claude 3.5, Gemini), 1,000 Traditional or Simplified Chinese characters typically correspond to 1,200–1,500 tokens.

Is the text I paste sent to any server?

Never. All counting and token estimation happens locally inside your browser.

How are spaces handled in the character count?

We display both Total Characters (with spaces) and Characters (no spaces) side by side for strict platform limits.

Accurate Counting for Mixed Chinese-English Documents and AI Prompts

Standard whitespace word counters fail on Chinese, Japanese, and Korean text because CJK scripts do not put spaces between words. Our counter separates CJK ideographs from space-delimited Latin words so bilingual essays, press releases, and social captions are measured accurately.

It also estimates BPE token consumption for modern large language models so you can size long prompts and context windows reliably.

Sizing Scripts for 3-Minute Pitches and 5-Minute Speeches

At a natural speaking pace of ~160 words/characters per minute, a 3-minute presentation requires roughly 480 units and a 5-minute speech requires around 800 units.

Method

CJK characters and Latin words are parsed independently via Unicode ranges; silent reading assumes 350 units/min, speaking assumes 160 units/min, and LLM tokens are estimated at ~1.4 tokens per CJK character plus ~1.3 tokens per English word.
