Overview
Helps you track your claude.ai usage caps based on tokens sent, and syncs across devices using firebase.
This extension helps you monitor how much of your Claude usage quota remains. It calculates token consumption from various sources including uploaded files, project knowledge, chat history, and AI responses. It will also send a notification when your usage limits have been replenished (if the site notified you that you were about to run out). Most elements in the chat UI (Namely the length, cost, estimate, caching status) have a tooltip explaining them further! Be sure to check them out. The extension tracks token usage from: - Files - Documents uploaded to chats or synced via Google Drive, Github, etc - Projects - Knowledge files and custom instructions - Personal preferences - Your configured settings - Message history - Full conversation context - System prompts - Enabled tools (analysis, artifacts) on a per-chat basis - MOST MCPs/Integrations - There are some limitations in cases where a "Knowledge" object is returned that I can't access, such as with web search Limitations: - Web search results - The full results are not exposed in the conversation history, so I can't track them properly (See above, Knowledge objects) - Research - Most of it happens on the backend, so I can't track it at all Token calculation is handled either through Anthropic's API (if you provide your key) or via gpt-tokenizer. It will additionally fetch your organization ID on claude.ai to synchronize your usage amounts across devices via firebase, as well as to store data on the amount of tokens you consumed before hitting the usage cap (to crowdsource more accurate counts).
