This tool is a simple Claude token calculator, built to help you quickly estimate token usage when working with Anthropic’s Claude models. It’s an easy-to-use interface where you can enter any text and receive an approximate token count based on a standard character-to-token ratio.
The tool works by converting the total number of characters in your input into a token estimate. This gives you a fast way to understand how much text you’re dealing with, whether you’re preparing prompts or just exploring usage patterns.

How Does This Token Estimator Work?
This free calculator gives a quick estimate of how many tokens your text might use with Claude. Tokens are how language models break down and process language — one token can be a word, part of a word, or even a single symbol or space. As a general rule, one token is roughly four characters in English.
The number provided is an estimate, as actual tokenization is more detailed and depends on the model’s internal system. Claude uses its own tokenizer, but the four-characters-per-token guideline remains a reliable estimate in most cases. This makes the tool useful for gauging input size, staying within token limits, or planning API usage. While not exact, it offers a close approximation to support practical workflows.
