Features & Capabilities

Claude Usage Tracker is a powerful Chrome extension designed to help users monitor their token consumption on Claude.ai. It calculates usage across multiple sources including uploaded files, project knowledge, personal preferences, message history, and system prompts. With real-time sync via Firebase, your usage data stays consistent across all your devices.

This extension offers detailed insights with tooltips explaining key elements such as length, cost, and token estimates. It integrates with Anthropic's API or uses a tokenizer to provide accurate token counts and notifies you when your usage resets or approaches its cap. While certain backend operations like web search results and research are limited in tracking, Claude Usage Tracker remains a comprehensive tool for managing your AI interactions efficiently.

Open-source and transparent, with code available on GitHub, this extension also maintains privacy by securely handling session keys and storage. Ideal for users who want precise control over their Claude.ai usage to avoid unexpected limits and optimize their AI experience.

Is Claude Usage Tracker Safe?

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Claude Usage Tracker requires a lot of sensitive permissions. Exercise caution before installing.

Risk likelihood

Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.
