About Token Counter

Token Counter is a free, private, browser-based tool for estimating token counts across all major AI language models. Whether you're using GPT-4o, Claude, Gemini, DeepSeek, or open-source models like Llama and Qwen — we help you understand how many tokens your text will consume before you send it to an API.

    🔒 100% Private. All token counting happens in your browser. Your text never touches any server. We don't store, log, or transmit anything.
  

Why We Built This

As AI adoption exploded, we noticed a gap: most token counters are either tied to specific providers (OpenAI's tokenizer only works for OpenAI), over-engineered with confusing UIs, or require accounts to use. We wanted something dead-simple — paste text, pick a model, get your count. No signup, no servers, no fuss.

How It Works

Paste or type your text into the input area
Select your model from the dropdown. We support GPT-4o, GPT-4, GPT-3.5, Claude 3.5 Sonnet/Opus, Claude 3 Haiku, Gemini 1.5 Pro/Flash, DeepSeek V3, Llama 3, Qwen 2.5, and Mixtral
Get instant results — token count, word count, character count, context window usage, and estimated API cost
Compare models to see how different tokenizers handle the same text

Accuracy

Our estimation uses proven approximation algorithms based on the 4-character rule, adjusted for punctuation, number clusters, uppercase sequences, and code patterns. Results are typically within 5-10% accuracy for English text. For production use requiring exact counts, we recommend using your model's official tokenizer.
