Show HN: Marketing Content Generator AI-powered multi-channel content platform

We built this for the Google Gemini 3 Hackathon. The platform takes product data (manual input or Shopify import) and generates marketing content across Instagram, Facebook, landing pages, and video.

The core idea: small teams spend hours creating the same content reformatted for each channel. We wanted to automate that end-to-end pipeline with AI agents.

Key pieces: real-time copy and image generation per platform, an AI Modify agent that transforms stock photos into product-specific visuals, compliance scoring against configurable rules, and a conversational landing page builder.

The hardest challenge was consistency — making the AI maintain brand voice and visual style across every output type.
