Set a monthly spend cap and read your usage

A monthly spend cap gives you a hard ceiling on what KM Hub can bill you in any month. Set it once, and AI work pauses automatically the moment your billable spend reaches the number you chose - no surprises on your card, ever.

Set your cap

1. Click Settings (the gear at the bottom of the left rail).
2. In the Settings sidebar, look for Billing & Money and open the Usage tab.
3. Find the Monthly AI spend limit field and enter a dollar amount.
4. Click Save limit.

That is it. The cap applies from that moment on and resets with each new month.

What the cap counts

The cap applies to your billable spend: pay-as-you-go fuel plus any extra usage beyond the credit included with your plan. It does not restrict the monthly allowance you already pay for - you always get that in full. In other words, the cap only limits the part of the month that would show up as an extra charge.

Read your progress

Beneath the limit field, a billable-spend progress bar shows how far into the cap you are right now. Checking it takes two seconds: if the bar is nearly full early in the month, you know your current pace will hit the ceiling, and you can decide whether to raise the cap or let AI pause when it gets there.

While you are on the Usage tab, the rest of the page helps you understand where the spend came from: the This month by feature table lists each feature with its uses and cost, and the Your usage this month stats show AI used, Fuel used, and your wallet balance side by side.

What happens when the cap is reached

AI pauses as soon as billable spend for the month hits your limit. Nothing is lost and nothing keeps billing - work simply waits. For the ways to resume, see "'AI is paused' - why it happens and how to turn it back on" in this folder.

Raise, lower, or remove the cap

1. Go back to Settings and open the Usage tab.
2. Type a new amount in the Monthly AI spend limit field, or clear the field entirely - blank means no limit.
3. Click Save limit.

The new setting takes effect immediately, so raising the cap is also the fastest way to resume work that paused mid-month.
