Convert words, characters, or any text to LLM tokens for GPT-4, Claude, and Gemini
Instant estimates, no API key needed Links directly to cost...
Paste or type your text and the calculator estimates token count instantly. As a rule of thumb, 1 token ≈ 0.75 words (or ~4 characters) for English text. The exact count varies by model tokenizer — switch between GPT-4 (cl100k) and others in the settings.
Approximately 1,333 tokens for typical English prose. The ratio is roughly 1 word = 1.33 tokens, though code, non-English text, and special characters can be significantly higher. Use this calculator to get an accurate count for your specific text.
Simple mode analyses raw text and shows token count. Composer mode breaks prompts into labelled sections (system prompt, context, examples, user message, output schema) for a detailed breakdown. Optimize mode adds token-reduction suggestions.
Each AI model uses its own tokenizer — a set of rules for splitting text into chunks. GPT-4 uses cl100k_base, which differs from the tokenizers used by Claude and Gemini. This calculator supports multiple tokenizers so you get accurate counts for the model you are targeting.
