Generate Influencer Posts with GPT-4, Google Sheets, and Media APIs

Description

This template transforms uploaded brand assets into AI-generated influencer-style posts — complete with captions, images, and videos — using n8n, OpenAI, and your preferred image/video generation APIs.

🧠 Who it’s for
Marketers, creators, or brand teams who want to speed up content ideation and visual generation.
Perfect for social-media teams looking to turn product photos and brand visuals into ready-to-review creative posts.

⚙️ How it works
Upload your brand assets — A form trigger collects up to three files: product, background, and prop.
AI analysis & content creation — An OpenAI LLM analyzes your brand tone and generates post titles, captions, and visual prompts.
Media generation — Connected image/video generation workflows create corresponding visuals.
Result storage — All captions, image URLs, and video URLs are automatically written to a Google Sheet for review or publishing.
