## Description (member-written data)
```text
How much would your AI coding usage cost at API prices, and how much does a subscription really give you before it cuts you off? Providers publish the price of a plan but not its limits in tokens. This project measures both from the logs your own tools already write, and pools anonymous results so the limits can be estimated from many people instead of guessed.

## What it does today

A small local program (Rust, MIT) reads Claude Code and Codex CLI logs on your machine. It reports:

- **API-equivalent cost** per model and month.
- **Plan limits per model.** Each time a tool reports the plan's percentage used, the usage logged since the previous reading shows how many of each model's tokens move the meter. That gives, per model, how many tokens fill a window.
- **A statusline readout** for
