Paste or type your text and see in real time how many tokens it consumes. See exactly how AI splits your content.
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 uses an estimate based on the BPE (Byte Pair Encoding) algorithm, similar to the cl100k_base tokenizer used by GPT-4. Accuracy is approximately 95%.
