本工具用 GPT 系列分詞器估算 token 數，不同模型實際分詞略有差異，數字僅供參考。Tokens are estimated using a GPT-style tokenizer; actual counts vary slightly by model.
完全免費，全部在你瀏覽器本機運算，不會上傳任何文字。Completely free and runs locally in your browser; your text is never uploaded.
價格為各模型每百萬 token 的參考單價，可能變動，請以官方公告為準。Prices are reference rates per 1M tokens and may change; always check official pricing.
Estimate how many tokens your text uses and what an API call will cost across providers such as OpenAI (GPT), Anthropic (Claude) and Google (Gemini). It runs in your browser, so your prompt text stays private.
API pricing is per token and costs add up fast at scale. Estimating tokens and comparing model prices before you build helps you choose the most cost-effective model and budget accurately.
It's a close estimate; exact counts vary slightly by each model's tokenizer.
Yes — most models price input and output tokens differently, and the calculator reflects that.
No — counting is done locally and nothing is uploaded.
