Free AI Token Counter
Every AI model charges by the token, so knowing your token count before you hit “send” can save real money — especially at scale. Paste any text into this free token counter to instantly see estimated tokens, words, characters, reading time, and the approximate API cost for a single call. It runs entirely in your browser: nothing you paste is uploaded or stored anywhere. Use it to right-size prompts, compare model costs, and keep your OpenAI, Anthropic, or Google AI bills predictable.
Estimates use the common ≈4 characters per token rule. Real tokenizers vary slightly by model.

Frequently asked questions
What is an AI token?
A token is the unit AI models use to process text — roughly ¾ of a word in English. “ChatGPT is great” is about 5 tokens. Providers bill input and output separately per million tokens, so token counts map directly to cost.
How accurate is this estimate?
It uses the widely accepted rule of ~4 characters per token, which is accurate within ~10% for English prose. Exact counts depend on each model’s tokenizer, but this is close enough for budgeting and prompt sizing.
Why should I count tokens before sending a prompt?
Long prompts cost more per call and eat into context windows. Counting first helps you trim filler, stay under limits, and predict spend — critical if you run thousands of API calls per month.
