Description

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. The source code can be found here: https://github.com/lugia19/Claude-Usage-Extension

Not accurate at all. It shows only 1% used even though 10–20% has already been used for that day.

Title: Good concept but causes interface issues - needs update for Claude Max The idea behind this extension is excellent - tracking token usage is genuinely helpful for managing Claude limits. When it worked, it provided useful insights. Unfortunately, it causes significant issues: - Makes certain Claude conversations zoom/magnify uncontrollably - Tracking is inaccurate with newer Claude Max plans - Causes performance issues with constant UI updates Had to uninstall due to the zoom bug making Claude unusable. Would love to reinstall once these issues are fixed, especially compatibility with Claude Max 20x plans. Giving 3 stars because the concept is solid and it did help track usage limits when it worked, but the current bugs are deal-breakers.
