Estimate tokens in your text, count words and characters, and visualize text segments in your browser.
AI models don't read text like humans. They split content into tokens — pieces of words, whole words, or even spaces and punctuation. In English, 1 token is approximately 4 characters. Token count determines usage cost and context limit for each model.
This tool estimates tokens using text patterns. It does not run the full BPE vocabulary of a specific model. Results vary by language and model; use the model’s official tokenizer for exact costs and context limits.
Token estimate based on text segmentation; the total may differ from each model’s tokenizer.
