An n8n automation workflow that turns structured client/project details into a polished, client-ready web-agency proposal using an LLM, renders it as branded HTML, and emails it out. The folder also includes a standalone static HTML preview of the generated proposal.
- Manual trigger feeds a hardcoded client/scope object (Bright Horizon Fitness) into the pipeline
- OpenAI node prompted to return strict JSON matching a fixed proposal schema (title, overview, scope, deliverables, week-by-week timeline, next steps, budget)
- Robust Code node that parses the AI JSON (handles object or fenced-string output, with parse-error fallback) and renders house-style responsive HTML
- Final step emails the rendered proposal via Gmail; proposal_preview.html shows the exact output design
Built with: n8n, OpenAI gpt-4o-mini (LangChain node), JavaScript (n8n Code nodes), Gmail node, HTML/inline-CSS email template
