AI Token Counter is a free Chrome extension designed to monitor token usage across various AI platforms such as ChatGPT, Claude, Gemini, Copilot, and Grok. This tool provides a real-time token counter that helps users track their context window usage, preventing unexpected context resets during important conversations. With a user-friendly interface, the extension features a draggable widget that displays a circular progress bar indicating the percentage of the token limit used, along with color-coded alerts to signal when users are approaching their limits.

The extension is lightweight and does not collect any user data, ensuring privacy while it operates entirely within the browser. It’s particularly useful for developers, content creators, and researchers who rely on AI for extended tasks, as it allows for better planning and more consistent AI interactions. By knowing the token count in real time, users can avoid losing critical information and enhance their productivity when working with AI models.
