TokenTracker 作者： JetLaggedByData

TokenTracker shows how much of your daily AI usage you have left, as a simple battery icon. It reads the usage percentage that Claude and Gemini already display on their own pages, and estimates ChatGPT usage from your message count (OpenAI publishes no official figure).

The extension pairs with the free TokenTracker desktop app over localhost, so your remaining usage is always visible in your system tray — no need to open each site to check.

Privacy first:
- No data leaves your machine. The only network traffic is to 127.0.0.1 (your own computer).
- It reads only usage numbers — never your conversations, prompts, or account details.
- No telemetry, no analytics, no third-party servers.

ChatGPT figures are an estimate and clearly labelled as such. Not affiliated with OpenAI, Anthropic, or Google.
