Need a few more credits this month?

Top-up packs add credits on top of your subscription. They stay valid for 12 months and only get used after your monthly credits run out.

Available to Hobbyist and Pro subscribers
Top-up S$10
+400 credits

Two extra books when you've nearly hit your monthly cap.

Best value
Top-up M$30
+1,500 credits

Roughly 7-8 extra books. Solid for a launch sprint.

Why credits + subscription?

Most AI tools force you to choose: predictable monthly bill, or pay-per-use anxiety. We give you both.

Predictable bill

Your monthly subscription is set in stone — no surprise charges, no end-of-month invoices.

No click anxiety

Credits inside your plan mean you've already paid for the work. Every Generate click costs you nothing extra.

Heavy users scale honestly

If you outgrow your plan, top-up packs are cheaper than upgrading. Power users pay more without forcing everyone else to.

Common questions

Still unsure? Email us and we'll answer in a day.

Each action — generating a page, refining an image — has a small credit cost shown right on the button before you click. Your subscription gives you a monthly credit allowance. Unused credits roll over (up to a cap). Sparky AI planning, PDF assembly, and our own quality-gate auto-regens cost zero credits — you only pay for the deliverable.
