Introduction

OpenSNS is an open-source AI marketing platform that automatically generates ad creatives from product URLs. It’s designed for marketers, e-commerce businesses, and agencies who need to create high-quality marketing assets at scale.

What Does OpenSNS Do?

Given a product URL, OpenSNS:

1. Scrapes the product page using Playwright (handles JavaScript-rendered content)
2. Analyzes the product to understand features, benefits, and target audience
3. Generates marketing angles for different messaging approaches
4. Creates ad copy optimized for each platform (Instagram, Facebook, Google Ads, Naver)
5. Generates images using AI (Fal.ai or ComfyUI)
6. Creates videos from images for TikTok, Reels, and Stories
