Claude Counter is a Firefox extension designed specifically for users of the Claude AI platform. This subscription-based tool provides three essential widgets integrated into the claude.ai composer, eliminating the need for additional tabs or guesswork. The Token Counter allows users to monitor their current token usage with a mini progress bar that indicates proximity to Claude's 200,000 token context limit. The Cache Timer features a live countdown, helping users understand how long their conversation remains cached, which is crucial for optimizing credit usage. Additionally, the Usage Bars offer session and weekly metrics, displaying exact percentages and reset countdowns, making it easier to manage usage limits effectively.

This extension stands out for its commitment to user privacy, as all processing is conducted locally without any external server involvement or data collection. Claude Counter is open source, ensuring transparency and security for its users. By providing clear visibility into session and weekly limits, this tool significantly enhances the overall experience of using Claude AI, allowing for more efficient and informed interactions.
