LLM Token Counter

LLM Token Counter provides precise tokenization for various language models directly in your browser. Key features: • Exact tiktoken counts for OpenAI models • Accurate estimates for Claude, Llama 3, Gemini, and Mistral • Live, color-coded token visualization • Character, word, sentence, and line counts • Average characters-per-token detailed This in-browser tokenizer processes your prompt instantly, showing you how text is broken down into tokens for different models. The color-coded chunks provide clear visual feedback, helping you understand token efficiency. Beyond simple counts, it offers average characters-per-token to give you a deeper insight into how each model handles text. The tool operates entirely client-side, ensuring your data never leaves your browser. There's no need for sign-ups, API keys, or any external data transmission, prioritizing your privacy and security. It even works offline after its initial load, making it a reliable utility for developers and content creators on the go. Ideal for engineers, prompt engineers, and content developers who need to optimize text inputs for various advanced language models. Use it for cost estimation, prompt refinement, and understanding token limits without compromising data privacy.
