AI Token Counter
Paste a prompt or document to get an estimated token count, useful for gauging context window usage and rough API cost before sending it to a model.

This is an approximation based on average character and word ratios (roughly 4 characters or 0.75 words per token in English). Exact token counts vary by model and tokenizer; use your model provider's official tokenizer for precise counts.
Frequently asked questions
How accurate is this estimate?+
It's a close approximation based on typical English character-to-token and word-to-token ratios, not an exact count from a real tokenizer. Different models use different tokenizers, so exact counts vary.
Why does token count matter?+
Every model has a maximum context window, and API pricing is typically based on token count, so knowing roughly how many tokens your text uses helps you stay within limits and estimate cost.
Is a word always one token?+
No, common short words are often one token, but longer or less common words can split into multiple tokens, and punctuation and whitespace count too.
