AI-Powered Social Video Scheduler

I need a self-running AI agent that keeps my Facebook, Instagram, and YouTube feeds active by creating and scheduling short-form video content based on the latest trends in my industry. The core workflow I have in mind is:

• Continuously scan reliable trend sources (popular hashtags, news, competitor channels, Google Trends, etc.) and decide which topics are worth turning into 30–90-second videos.
• Draft an engaging video script, suggested on-screen text, captions, hashtags, and thumbnail headline for each idea.
• Optionally generate a simple talking-head or text-overlay video, or hand the script off to my editor when human recording is required.
• Schedule the finished asset automatically in a content calendar so it publishes natively to Facebook Reels, Instagram Reels, and YouTube Shorts at the optimal time for each platform.

The finished solution should run on affordable, well-documented tech (Python, Node, or no-code stacks such as Make/Zapier plus OpenAI API, Meta Graph API, YouTube Data API). A small dashboard or Google Sheet where I can review queued posts before they go live will keep me in control.

Acceptance criteria
1. Trend-detection module surfaces at least five relevant ideas per week.
2. Scripts meet each platform’s character limits and include calls-to-action and hashtags.
3. Successful auto-posting demo to all three channels with correct formatting.
4. Clear hand-off instructions so I can maintain or extend the agent myself.

If you have proven experience combining generative AI with social media scheduling tools, I’d love to see a quick proof of concept or a short outline of your proposed tech stack when we start.
