LLM Token Estimator FAQ
What is a token?
A token is a small piece of text that AI models read and charge for. In English one token is about 4 characters, or roughly three-quarters of a word.
Is the token count exact for ChatGPT and Claude?
It is an estimate. Each provider uses its own tokenizer, so the real count can differ slightly.
Why does Urdu or code use more tokens?
Tokenizers are trained mostly on English text, so other scripts and code are split into more, smaller pieces.
How do I estimate the cost of a prompt?
Enter the price per million tokens from your provider’s pricing page and the tool estimates the cost for the text you pasted.
Is the LLM Token Estimator free?
Yes. The LLM Token Estimator is completely free with no sign-up, no daily limit and no watermark.
Is it safe to use the LLM Token Estimator with private files?
Yes. The LLM Token Estimator runs entirely inside your web browser, so your files and text are never uploaded to any server.
