AI Visual Inspection App for Cleaning & Property Setup

Título recomendado para la oferta: AI Visual Inspection App for Cleaning & Property Setup (iPhone + Android) Y el texto en inglés: We are looking for a programmer or small development team to create a very simple mobile app/web app for cleaning control and vacation rental property setup. The MOST IMPORTANT part of this project is AI image comparison. The main idea is that every room or area of the property has a “reference photo” showing exactly how it should look. After cleaning or setup, the staff takes a new photo with the phone, and the AI compares both images automatically to detect visual differences. Examples of what the AI should detect: * bed not properly made, * cushions/pillows not correctly positioned, * missing decorative objects, * missing items inside the fridge, * sunbeds not positioned correctly, * objects out of place, * messy areas, * visible missing items, * cleaning or presentation issues. The app should clearly show the detected differences, ideally highlighting them visually on the image or describing what is wrong. Basic workflow: 1. The administrator creates areas/zones of the property: kitchen, bedrooms, bathrooms, living room, terrace, pool area, fridge, wardrobes, etc. 2. A reference photo is uploaded for each area. 3. Cleaning staff opens the app from their phone. 4. They go through each area step by step. 5. They take a new photo after finishing. 6. The AI compares the new image with the reference image. 7. The app indicates whether everything is correct or shows the detected differences. 8. A supervisor can review everything from another phone or computer. The app must work on both iPhone and Android, preferably as a web app or hybrid app. Very important: * Extremely easy to use. * Very visual interface. * Fast mobile experience. * Designed for non-technical cleaning staff. The first version can be simple and “homemade.” We mainly want to test the concept this summer in a real vacation rental property. If it works well, we plan to improve it later and potentially commercialize it. We are specifically looking for someone with experience in: * AI visual analysis, * image comparison, * computer vision, * object detection, * or similar technologies. Please include: * your relevant AI/image analysis experience, * recommended technologies, * estimated cost for a first working version, * estimated timeline, * and examples of similar projects if available.
