Cursor Usage Calculator – Built with Cursor Plan Mode

Discussions
1

I always wondered how much Cursor I actually used each month —
too lazy to count requests or download CSVs.

So I tried Cursor’s new Plan Mode to build a simple extension that
tracks usage, costs, and model breakdowns.

It works, but I’m not sure everything is accurate yet.
If you can test it and share feedback, I’d really appreciate it.
(Inspired in part by the “Cursor Used” extension.)
