What am I actually paying for?

The plugin and this web app are open source, and you can self-host the whole thing. Plus supports continued development and pays for the AI requests themselves. In return, you get a setup that works immediately without creating a provider account, managing another bill or pasting a key into your reader. On the free plan, you handle that part yourself and keep all the same Lunote features.

What happens when I run out?

Explanations stop until the allowance resets, and your reader tells you so. There is no overage and no surprise bill — the cap is the whole point. Everything you have already saved stays where it is.
