Claude Pulse Browser Extension Surfaces Token Counts, Cache Timers, and Rate Limits on Claude.ai
Frustrated by hitting the 5-hour limit mid-conversation with no visibility into token or context usage, a developer built Claude Pulse — a Chrome extension that adds a small dashboard to claude.ai.
Key Features
- Real-time token counts per message and total context used
- Prompt cache window timer showing when caching is about to expire
- Rate limit progress bar tracking usage against limits
- Chat export to Markdown format without copy-pasting
All processing is client-side — no data leaves your browser. Token counts are approximations using a tiktoken-style method since Anthropic doesn't expose exact numbers in the UI; the developer estimates error within a few percent.
Open Source & Future Plans
Source available on GitHub: samirpatil2000/claude-pulse. The author describes it as "rough around the edges" and is considering adding per-conversation cost estimates, but is unsure if that would be useful or just noise.
