What it is AI-extracted, prompt v1, taxonomy v1, 2026-08-30, confidence not recorded
A minimal browser extension (and userscript) that overlays token counts, cache countdown timers, and session/weekly usage bars on claude.ai. It works by intercepting Claude's API responses and using a vendored o200k_base tokenizer, with all data kept local.
Use cases
- show token count for my claude.ai conversation
- track how long my claude conversation stays cached
- see accurate claude usage limits with reset countdowns
- monitor context window usage against the 200k limit
- browser extension to display claude rate limit usage bars
- userscript to track claude token usage locally
When to choose
- you use claude.ai in the browser and want live token and usage visibility
- you need more precise usage fractions than Claude's rounded /usage page
- you want a privacy-friendly tool with no external servers or tracking
When to avoid
- you use Claude via API or desktop app rather than claude.ai
- you need exact token counts rather than approximations
- you need a tool that works outside Chromium/Firefox browsers
