TokenScope
Real-time, privacy-first monitoring of your LLM API usage
TokenScope is a lightweight browser extension that quietly watches the LLM API calls made by any tab - ChatGPT, Claude, Gemini, or any OpenAI-compatible endpoint - and shows you in real time exactly how many tokens went in and out. Zero config. No account needed. 100% local - nothing ever leaves your browser. Works with ChatGPT, Claude, Gemini, OpenRouter, DeepSeek, and any custom gateway.
I built TokenScope because I was tired of guessing how many tokens I was burning through across different AI tools. As someone who uses ChatGPT, Claude, and various self-hosted models daily, I wanted a single, privacy-first view of my token usage that didn't require signing up for yet another service.
Key features:
- Zero configuration - install and it just works
- Supports OpenAI, Anthropic, Google Gemini, and any OpenAI-compatible endpoint
- 100% local - all data stays in your browser
- Real-time token counting with live cost estimates
- Export to JSON or CSV
- Bilingual UI (English & Chinese)
It's completely free and open source. Would love to hear your feedback! 🚀
