AI Token Calculator

It's a rough approximation based on about four characters per token. Real tokenizers split text differently, so treat the result as a ballpark for planning rather than an exact billing figure.

This calculator is designed to run in your browser. The text you paste is used only to produce the estimate shown on this page.

Different models use different tokenizers and vocabularies, so the same text can map to slightly different token counts. Always confirm with the provider's own tooling when precision matters.
