Claude Usage Meter von Shafayat Ahmed Alif

Claude Usage Meter brings transparency to your AI workflow by showing your exact usage metrics directly inside the Claude.ai chat interface. It helps you stay within limits and manage your context window without leaving the conversation.

Key Features:
1. Live Usage Bars: Displays two progress bars (Session and Weekly) at the bottom of the chat composer.
2. High Precision: Shows usage to the decimal point (e.g., 22.832%), sourced directly from the API stream.
3. Token Counter: Real-time calculation of conversation tokens with a 200k context window indicator.
4. Cache Timer: Shows exactly how long your conversation remains prompt-cached to save on usage limits.
5. Visual Alerts: Color-coded bars (Blue → Amber → Red) signal when you are approaching limits.
6. One-Click Refresh: Instantly sync data with Claude's servers.

How it works:
The extension reads usage data your browser already receives from Claude's servers. It intercepts the network stream to extract the hidden message_limit field. Token counting is performed locally using a bundled BPE tokenizer.

Privacy First:
1. Runs 100% locally in your browser.
2. No external server requests.
3. No data collection or analytics.
4. No conversation content ever leaves your machine.
