Generate & Optimize Brand Stories with Ollama LLMs & Google Sheets

Automates brand story generation, evaluation, and iterative optimization using local Ollama LLMs and LangChain agents, saving polished stories to Google Sheets for marketers.

This n8n workflow empowers marketers, brand consultants, and social media strategists to create high-quality brand stories effortlessly. Triggered by chat input, it uses Ollama-hosted LLMs (phi4-mini and qwen3:4b) via LangChain agents to generate structured stories, evaluate them for tone, uniqueness, quote inclusion, and emoji absence, then iteratively optimize until quality criteria are met. Final stories are automatically appended to a Google Sheet for easy publishing or reuse. Key benefits
