The premium engine add-on

The premium engine add-on lifts the 10% limit on Grok and Claude. It costs $39 a month and buys 100 extra checks a week on either engine.

Add it from Plan and billing, under Premium engine add-on.

Why it is not on the pricing page

Because it is not a decision to make while you are working out whether to buy Keylight at all. You meet it when you hit the limit and want more, which is the right moment for it.

The public pricing page stays four tiers and one capacity add-on.

One add-on rather than two

Grok costs more than Claude, and the add-on is priced against Grok. Spent entirely on Grok it still works for us; spent entirely on Claude it works comfortably.

A separate cheaper Claude add-on would have priced around $15, and was not worth an extra row on the page or an extra decision for you.

It is not extra capacity

This is different from buying extra capacity. Extra capacity adds tracked questions across all engines. This add-on lifts a per-engine limit. If you want more questions tracked, you want extra capacity; if you want more of them on Grok or Claude specifically, you want this.
