Your first AI prompts

Paste these into Claude, Cursor or Lovable, in order. Check that each one works before moving on.

PROMPT 1 OF 3

Build a mobile friendly web app called Estimate Buddy. A contractor signs in, creates a job, uploads photos and types a short description. Start with sign in, the job list and the photo upload screen only.

PROMPT 2 OF 3

Add an AI step: send the job description and photo captions to an AI model and return an itemized estimate as JSON (line items with labor hours, material cost and totals). Show it in an editable table.
