Token Calculator
Paste any text to estimate how many tokens it uses for GPT, Claude, Gemini and Llama.
Frequently Asked Questions
Is this token calculator free?
Yes, completely free with no signup required.
Is my text uploaded anywhere?
No. Everything is calculated locally in your browser — your text is never sent to a server.
How accurate is the token count?
It's an estimate based on average characters-per-token ratios (around 4 characters per token for English), not the exact output of a specific tokenizer like OpenAI's tiktoken. For billing-critical or exact counts, use the provider's official tokenizer.
What is a token?
A token is a chunk of text a language model processes — often a whole word, part of a word, or a punctuation mark. Models are priced and rate-limited by token count, not character or word count.
Does this work for GPT, Claude, Gemini and Llama?
Yes — pick a tokenizer family to use its typical characters-per-token ratio for the estimate. Exact tokenization differs slightly between providers, so treat the result as an approximation.
