Attach Files to Your Prompts
You can now attach files directly in the chat when building your app.
Drag a file into the input or use the attachment button to add it to your message. The agent reads the file and uses it as context for whatever you're asking it to build.
A few ways people are using this:
CSV or JSON data Describe a table or list view and attach the data file. The agent can model your schema directly from your actual data rather than guessing.
Design references Attach a screenshot or mockup and tell the agent to match it. Works well for getting layouts close on the first pass.
Spec documents If you have a requirements doc, product brief, or any structured description of what you want, attach it and the agent will use it.
File attachments work on web and iOS.
