What is Credit Top-Up?
A one-time credit purchase for bursts beyond plan quota. Top-ups keep long builds moving without forcing a plan change mid-project.

AI Credits
The metered unit for AI work in BYOB: planning, generation, and agent runs draw down a balance tracked per project. Credits make heavy context work visible instead of hiding it in a flat fee.
Subscription Plans (Free / Pro / Max)
Quota-gated tiers bounding credits, projects, and features. Plans set the default budget; top-ups absorb spikes; pay-as-you-go covers the rest.
Billing Action
The structured paywall signal (insufficient credits, quota exceeded, plan required) with a checkout URL. Generated apps use the same pattern to gate their own premium features.
Guided Preflight
The multi-step setup wizard BYOB runs before generating code: refining the prompt, identifying features, proposing UX direction, and choosing data options. Planning first is what separates coherent apps from random screens.
Lucky Build (Autopilot)
The one-shot fast path that skips guided setup and generates directly from the prompt. Best for experiments and landing pages; guided preflight wins for anything with data or auth.
Pass-1 Build
The uninterruptible first generation surface: styles, layout, page, components, then validation. Letting pass one finish prevents half-built states that later edits have to repair.
