Tokens can be thought of as pieces of words. Before processing, the input is broken down into tokens that don't necessarily align with word boundaries.
For a detailed explanation of tokens and how to count them, see the OpenAI Tokenizer Guide.
This calculator uses the actual GPT-2 tokenizer (the same one used by many OpenAI models) to provide precise token counts. It:
Note: While this calculator uses the GPT-2 tokenizer, some newer models might use slightly different tokenizers. For model-specific token counts, please use OpenAI's Tokenizer tool.

Text processing:
Tokens are pieces of words that models process individually. Depending on the tokenizer, tokens may represent whole words, parts of words, or even punctuation.
This calculator uses the GPT-2 tokenizer to provide accurate counts of tokens, words, and characters in real time. All processing is done locally in your browser.
Absolutely. No data leaves your browser; all token calculations are performed locally, ensuring your text remains private.
While this tool uses the GPT-2 tokenizer, which is common among many models, some newer models might use other tokenization methods. For those, the token counts might differ slightly.
