TokenSensei was created to help users around the world better understand and manage the costs of using Large Language Models (LLMs). Whether you're a developer, researcher, student, or hobbyist, knowing how many tokens your prompts consume is essential for optimizing usage and avoiding unexpected expenses.
Our goal is to provide a free, accurate, and universal token calculator that supports multiple LLM families—including GPT, Claude, Llama, and others. By giving users the ability to compare token counts and estimate API costs, TokenSensei helps individuals and teams plan, budget, and optimize their AI workflows.
We built TokenSensei in multiple languages to make it accessible to a global community. From day one, we’ve aimed to support users regardless of their region or native language—because tools like this should be for everyone.
We know ads can be a distraction, and we appreciate your understanding. Displaying ads allows us to keep the site free and running for users worldwide. We don’t track or sell your data—our goal is simply to offer a lightweight, helpful tool that anyone can use.
TokenSensei is still new, and we’re actively working to improve it. We hope that each time you visit, you get the answers you need and that it helps you use LLMs more efficiently and effectively.
Thank you for using TokenSensei—we’re just getting started.
