Create a Project

Home is where new Castaly projects begin. Describe the outcome you want, add any useful context, and Castaly creates a Project so the work can continue in Chat.

Use Home to start something new. To continue work you have already started, open the Project from Projects or Recent projects and keep working in that Project’s Chat.

The Home composer

The composer is where you give Castaly the initial intent for a new Project. You can write a short idea, paste a longer brief, add screenshots, or attach documents.

At the top of the composer, choose how Castaly should treat the material you provide:

💡Start from an Idea

Choose this when your written description should lead. References can still help, but your text defines the direction.

🖼️Start from a Reference

Choose this when screenshots, prototypes, or documents should lead. Your text adds instructions, constraints, or notes about what should change.

Start from an Idea is selected by default. Switching modes does not clear your text or attachments; it only changes what Castaly treats as the primary source. See Supported Inputs for the full list of text, images, and files you can add.

What happens after you send

1. 1

   Send your intent

   The send button activates once you type a description. Attachments provide context, but Castaly still needs words to anchor the Project.

2. 2

   Castaly creates the Project

   Castaly creates a new Project and gives it a working name. There is no setup wizard or naming step, and you can rename the Project later.

3. 3

   Chat starts the first understanding

   You land in the Project workspace. Chat begins interpreting your input, then Castaly drafts the first Spec and Graph so you can review the structure before building.

Creating a Project is the start of the loop, not the end of setup. From there, you refine in Chat, review the Graph and Spec, and press Build when the structure is ready.

Return to existing projects

Home also gives you a quick way back to recent work. Below the composer, Recent projects has two tabs:

• Recent — projects you worked on most recently.
• Published — projects with a published version.

Each tab shows up to three projects. Use View all to open the full Projects list.

If you have not created any projects yet, Recent projects shows an empty state that points you back to the composer.
