Every project starts the same way: you type what you want to build — on the dashboard or the landing page — and land on the build configurator. Your idea is shown at the top in your own words; a change idea link takes you back if it came out wrong. If you attached images with your idea, they appear as chips under it. Images are uploaded to the project and reach the agent with your first message.
If you signed in after typing your idea, attached files may not survive the redirect — the page will tell you if so, and you can simply re-attach them in the chat once your workspace opens.

The choices

Model

Which AI model does the building. A sensible default is pre-selected; the picker lists the available models if you want a different one. The same picker appears later in the workspace, so this is never final.

Stack

What lands on disk when your project boots: If your idea needs to store data or sign users in, pick Full-stack or Supabase.

Approach

In every approach you review and approve the plan before anything is built. A Recommended badge follows your stack choice — frontend-only projects lean Quick build, projects with a real backend lean Guided design. Express is never recommended; choose it when speed matters more than reviewing each screen before it is built. You can override either way.

Look (Express only)

Choosing Express shows a set of ready-made looks. Each sets the app’s colours, typefaces, corner style and icon set.
  • Pick for me is selected to begin with: we choose the look that fits your idea and tell you which one, and why, before you approve the plan. Once your idea says enough, the tile names the look we would likely pick and draws it. The pick is confirmed when the requirements are written.
  • Or pick a look yourself. Each tile draws a piece of a screen in the look’s own colours, corners and kind of type, and says who the look is for. Select a tile to read how the look feels and which typefaces it uses.
Every screen is built in the look you end up with. You can change its colours afterwards from the running app. Quick build and Guided design choose the look in their design step instead, so they show no picker here. See Design-first builds for what Guided design looks like.

Fidelity

The most consequential choice on the page:

Client (optional)

If you build for others, assign the project to a client here. It shows up under that client on your clients page.

Tier

How Creator talks to you: Your preferred default tier is set in Preferences. As the page itself says: you can change this anytime — your project keeps its data.

Start building

The bar at the bottom summarizes the run — client · stack · approach · fidelity · tier — with an honest time estimate (“Verified · a few min” for Production, “Preview · under a min” for Prototype; deliberately no made-up dollar figure). Press Start building and your workspace opens. If the model you picked needs an API key that isn’t configured, the page tells you exactly that (“API key required for …”) and opens the settings for that provider — paste a key or pick a different model. Next stop: reviewing the plan.
