Designing and exploring a project is free. The BuildIn Plan and credits are one-time purchases. No subscription is required to use any of it.

Questions people ask before buying

Why is the BuildIn Plan one-time per build, not a subscription?

A plan prices the AI work and the deliverables for one component you build. You buy it once, it stays yours, and it never expires — re-opening it costs nothing. A further component extends the plan; you never re-buy what you own.

What are credits for, and do they expire?

Credits meter extra AI work — additional generations and variations — beyond the first free design. Every charge is shown before you confirm it, and credits never expire. They are separate from the BuildIn Plan and never required to use it.

What happens if a generation fails?

You are not charged. A generation that fails — timeout, provider error, anything — refunds its credits automatically, and the balance line in your workspace shows it.

Is designing free?

Yes — designing, exploring and reading your feasibility costs nothing and needs no plan. You pay once, when you want to take the project with you: the exports, the printed guides, the full render downloads.
