claude-usage-bar

Claude Usage Bar is an open-source Chrome extension designed to enhance the user experience on Claude.ai by providing real-time usage data at the top of every page. The extension helps users monitor their Claude usage limits, including the 5-hour cap, weekly quotas, and extra credits, along with a live token counter for the context window and a countdown for the prompt-cache. Functioning entirely within the user's browser, it ensures privacy by avoiding external analytics and servers.

Key Features

• Usage Bar: Displays the percentage of the 5-hour limit used with a reset countdown. It can be positioned at the top of the page or within the chat box while reflecting Claude's coral palette and supporting both dark and light themes.
• Hover Panel: Offers a detailed view of usage limits including the 5-hour maximum, weekly limits, extra credits, and routines, each displayed with the respective percentage used and reset time.
• Context Window Counter: A donut-shaped token counter showing the amount used of the context window (default 200k tokens) during the current chat, differentiating between current context and total tokens used.
• Prompt Cache Timer: Tracks the countdown for the prompt-cache's time-to-live (TTL) after an assistant reply, aiding in efficient follow-ups without exceeding token limits.
• International Language Support: Available in 14 languages, the extension automatically follows the user's browser language settings.

Privacy Assured

Claude Usage Bar operates securely by making same-origin requests to Claude.ai, ensuring no data is transmitted elsewhere. Conversations are processed only in memory for token estimation, with no external storage or telemetry involved. For more details, refer to the privacy policy.
