About this tool

Count and visualize LLM tokens with model-aware BPE. Cost estimate from catalog. Free, client-side. LLM Token Counter runs in the browser on DevTools. There is no signup, and your input stays on this device unless the tool explicitly performs a live network lookup.

What this tool does not do

  • LLM Token Counter is a free in-browser utility, not a hosted API. It does not keep server-side history and is not a substitute for production verification in your own stack.
