Arpia Codex in SPA Studio

Within SPA Studio, the assistant appears as Arpia Codex — SPA Studio, the AI assistant for your Single Page Application. Open the Codex panel, select a model, and pick a mode:

• Explore – Reads and explains your code; changes nothing.
• Planning – Drafts a plan and waits for your approval.
• Build – Applies changes to your files.

Full build flow: to create an app, edit code, connect data, preview, and publish end to end, see Single-Page Apps (SPA).
