## Overview

CribeIt is an offline-first Flutter demo assistant for Indian artisans, guiding a user from onboarding through product preparation and simulated marketplace publishing. The documented workflow covers image enhancement, multilingual catalog drafting, voice-language detection, cost-based pricing, listing preview, and publishing to simulated buyer/ONDC/GeM channels. The README identifies a shared ChangeNotifier service for app logic and demo AI, plus local persistence and seeded data. Dart implementation excerpts were not provided, so links between screens and services below reflect documented flow only.
