# Token Counter

Paste any text and see how it tokenizes across Claude, GPT, and other model families. Powered by [`agentfit`](https://pypi.org/project/agentfit-py/).

## Why?

- Different tokenizers split the same string very differently — Claude often uses ~half the tokens GPT does for the same Chinese / emoji input.
- Useful when budgeting prompts and deciding which model to use for non-English content.
- Sanity-check your own token counter against a reference.
