Token counter

Token counter — see how language models read your text

Count tokens for OpenAI, Llama, Gemma, Mistral and Qwen tokenizers — for pasted text or a whole TXT, DOCX or PDF — and see every token highlighted. See how full typical context windows are and estimate the cost at your provider’s price.

Stays on your computer — your text never goes to the internet

The tokenizer files download to your computer once on first use, then everything is processed by your browser. Nothing is uploaded to a server — not even to Hypervision. No account, no storage, no tracking.
