Free AI Token Counter
Paste your text to estimate how many AI tokens it uses, alongside word and character counts. Useful for staying within model limits and understanding AI costs. It runs in your browser session — no sign-up, no limits, and your text stays private.

About this AI token counter
AI language models like GPT and Claude do not read text word by word — they break it into tokens, which are chunks of text roughly four characters long. A token can be a whole word, part of a word, or a punctuation mark. Models charge and set limits by tokens, so knowing your token count helps you stay within context windows and estimate costs.
This tool gives a fast heuristic estimate of your token count, blended from character and word signals, along with your word and character totals. It runs entirely on our server with no third-party calls, so your text stays private.
Because every model uses its own tokenizer, exact counts vary slightly by model. This estimate is meant for guidance — to gauge whether your prompt fits a limit or how large a piece of content is — rather than exact billing. As a rule of thumb, English text averages about one token per four characters.
Frequently asked questions
How does the AI token counter work?
Paste your text and click Count Tokens. The tool gives a heuristic estimate of tokens, plus word and character counts.
Is it free?
Yes. It is completely free with no sign-up and no usage limits.
What is a token?
A token is a chunk of text a model processes — roughly four characters in English. It can be a whole word, part of a word, or punctuation.
Is the count exact?
It is an approximation. Each AI model uses its own tokenizer, so exact counts vary slightly by model. This estimate is for guidance.
Why do tokens matter?
Models limit input and output by tokens and often price by them, so token counts help you stay within limits and estimate cost.
