Note: These are estimates based on average token lengths. Actual token counts may vary depending on the specific content, language, and special characters. For precise counts, use the official tokenizer APIs provided by each model vendor.
Features
Our AI Token Counter helps you understand how your text will be tokenized by large language models like ChatGPT, Claude, and GPT-4. Tokens are the fundamental units that AI models use to process text—understanding token counts is essential for staying within context limits and estimating API costs.
The tool provides estimates for multiple tokenization schemes including cl100k (used by GPT-4 and ChatGPT) and Claude's tokenizer. While exact token counts may vary slightly between models, these estimates help you plan your prompts and manage costs effectively. Use it to optimize your AI interactions and avoid unexpected truncation or overage charges.
