HOW IT WORKS
Tokens are the tiny pieces of text AI models read and write.
For everyday English, one token is roughly ¾ of a word. TokenMeter uses that practical estimate and adjusts slightly for punctuation-heavy text. It’s ideal for planning, comparing options, and catching unexpectedly large prompts.
Want exact billing? Use this as the fast first check, then validate critical workloads with the tokenizer and pricing page of the AI provider you use.
