AI Service Platforms — Monorepo

A collection of AI-powered SaaS platforms sharing a common backend library.

Architecture

AIserviceplatforms/
├── shared/                 # Reusable Python modules (auth, payments, AI, DB)
├── propertiesgenie/        # Platform 1 — AI real-estate listing descriptions
├── <future-platform>/      # Platform 2 — (add new folder per platform)
└── README.md

Shared Module (shared/)

Module	Purpose
config_base.py	Base Flask config (DB, PayPal, OpenAI, Mail)
database.py	SQLAlchemy instance + model mixins
auth.py	Blueprint factory for register / login / logout
payments.py	PayPal server-side order verification
ai_client.py	OpenAI API wrapper
factory.py	App setup helper (CORS, login, errors, etc.)

Every platform imports from shared/ — no code duplication.
