TokenCounter

What is TokenCounter?

TokenCounter is a sophisticated and privacy-focused tool designed to accurately count tokens and estimate usage costs for a wide range of widely-used LLMs such as GPT-4, Claude-3, Llama-3, and others. It operates entirely client-side in the browser using efficient tokenizers from the Transformers.js library, ensuring prompt data never leaves the user's device. This enables developers, researchers, and AI users to optimize prompt length, manage budgets, and avoid token limit errors effectively without compromising data privacy.

Key Features

• Multi-Model Token Counting

  Supports tokenization for numerous popular LLMs including OpenAI, Anthropic, Meta, and more, providing accurate token counts tailored to each model's specific tokenizer.

• Client-Side Privacy

  Performs all token counting locally in the browser, ensuring that user prompts remain confidential and are not transmitted to any server.

• Real-Time Token and Cost Estimation

  Instantly displays token counts and estimates input costs as users type or paste text, enabling efficient prompt optimization.

• Browser-Based and Easy to Use

  No installation required; runs purely in-browser with a user-friendly interface suitable for both beginners and experts.

• Continuous Model Support Expansion

  Regularly updated to include more LLMs and improve token counting accuracy, reflecting the evolving AI landscape.

Use Cases

• Prompt Optimization : Helps AI developers and users tailor prompts to fit within token limits to avoid errors and reduce unnecessary costs.
• Cost Management : Enables budgeting and cost estimation for API usage by calculating tokens and estimating expenses before sending requests.
• Research and Development : Supports AI researchers in analyzing token usage patterns across different models for experimental and comparative studies.
• Educational Tool : Assists learners and AI enthusiasts in understanding tokenization and model-specific token limits through hands-on interaction.
