Question 1

What are tokens and why are they important?

Accepted Answer

Tokens are the basic units into which AI models break down text. A token can be a word, part of a word, or a punctuation mark. The token count determines the cost of API calls and whether a text fits into a model's context window.

Question 2

How accurate is the token count?

Accepted Answer

The token count uses the official Tiktoken library from OpenAI and is 100% accurate for GPT models. For other models like Claude or Gemini, an approximation is used that is usually very close to the actual value.

Question 3

Which file types are supported?

Accepted Answer

The token counter supports all common text files: .txt, .md, .csv, .json, .log as well as programming files like .js, .py, .java, .html, .css and many more. Binary files like images or PDFs are not supported.

Question 4

How do tokens differ between languages?

Accepted Answer

The token count varies by language. English text typically requires fewer tokens than German text. Languages with different writing systems (e.g., Chinese, Arabic) may require significantly more tokens.

Question 5

Are my texts stored or sent to servers?

Accepted Answer

No, all calculations take place entirely in your browser. Your texts are neither stored nor transmitted to servers. The tool works completely offline after loading the page.
