AI Token Counter & Cost Estimator
Estimate how many tokens your text will use in AI models like GPT and Claude, and estimate the API cost.
Estimate only — actual tokenization varies by model. Roughly 1 token ≈ 4 characters or 0.75 words in English.
About & How to Use
Paste any prompt or document to get a quick estimate of how many tokens it will consume in large language models like GPT-4 or Claude, plus an approximate API cost based on the price you enter.
