Token counts are estimates. Actual counts depend on the model's tokenizer (BPE for GPT, SentencePiece for others). Estimates are most accurate for plain English text.
About Token Estimation
Tokens are the basic units that language models process. A token can be as short as one character or as long as a word. For English text, a rough rule of thumb is 1 token per ~4 characters, or ~0.75 tokens per word. Code, special characters, and non-English text often use more tokens. Prices shown are approximate and subject to change.
About This Tool
Token Counter is a utility tool that counts the number of tokens in your text, crucial for managing costs and staying within limits when using AI APIs. Ideal for developers, writers, and anyone working with natural language processing.
Simply paste or type your text into the input field. The tool processes it instantly to display the token count. Outputs include total tokens and breakdown by sentence or paragraph if selected.
Use Token Counter to optimize API usage in projects like chatbots or document summarization. It runs entirely within your browser, ensuring privacy as no data is sent or stored.
