About TokenCounter.cc

TokenCounter.cc is a free, privacy-first tool for counting tokens and estimating LLM API costs across GPT, Claude, Gemini and Llama. It was built to answer three questions developers and writers ask every day: How many tokens is this? What will it cost? Will it fit in the context window?

Why this tool exists

Most "token counters" either send your text to a server, give vague word-based guesses, or only cover one model. We wanted something different: a counter that is exact for GPT, transparent about estimates for other providers, and completely private — so it's safe to paste a confidential prompt, proprietary code, or an unpublished draft.

How it works

• Exact GPT counts. The tool runs OpenAI's real tiktoken tokenizer (o200k_base and cl100k_base) directly in your browser. The number matches the OpenAI API byte-for-byte.
• Honest estimates. Anthropic and Google don't publish their tokenizers, so Claude and Gemini counts use a tuned character-based approximation (typically within ~10–15%), always labelled "Estimated".
• 100% in-browser. There is no backend. Your text is never uploaded, logged or stored. Read our privacy policy for details.

Who built it

TokenCounter.cc is built and maintained by Token Counter Team, a small team that works with LLM APIs daily and writes about tokenization, prompt efficiency and AI API costs. The goal is simple: a fast, accurate, no-nonsense utility that respects your privacy and your time. Questions or feedback? Get in touch.

Accuracy & pricing

Model pricing shown in the tool is per 1M tokens and is reviewed periodically (last reviewed June 2026). Provider pricing changes often, so always confirm against official provider pages before billing decisions: OpenAI pricing, Anthropic pricing, and Gemini pricing.
