What is this estimate?

This is an approximation tuned per writing system: about 4 characters per token for Latin text and about 1 character per token for CJK, Arabic, Korean, and Thai. Real model tokenizers can differ by a few percent.

What Is a AI Token Counter?

The AI Token Counter estimates the number of tokens in any text using a per-script approximation. It also reports characters, words, bytes, lines, CJK characters, and emoji, giving prompt engineers and developers a fast way to size prompts before calling a language model.

Frequently Asked Questions

The tool uses an approximation tuned per writing system. Latin text averages about 4 characters per token, while CJK, Arabic, Korean, and Thai average around 1 token per character. Real tokenizers may differ by a few percent.
The heuristic is broadly aligned with byte-pair-encoding tokenizers such as OpenAI's cl100k_base. It is not identical to any single vendor's tokenizer.
No. All counting happens locally in your browser and your text is never sent to a server.
