This end to end automation creates complete Twitter posts by:

Taking your topic input (e.g., "Agentic AI") via chat interface

Generating fresh, research-backed content using AI agents:

First agent uses GPT-4.1-MINI + Tavily to bypass LLM knowledge limits with real-time web data

Second agent creates optimized prompt for image generation

Producing custom visuals through OpenAI's gpt-image-1

Delivering polished drafts (text + image) via Gmail for review
