Tailor your Google Docs CV to any job using Ollama and Groq

CV Keyword Optimizer An AI-powered n8n workflow that automatically tailors your resume to any job description by injecting relevant keywords — without touching your formatting, layout, or design. --- How It Works Architecture Why Two AI Models? | Step | Model | Why | |------|-------|-----| | Keyword Extraction | Ollama llama3.1:8b (local) | Free, private, no API costs. Reasoning about which keywords actually matter for ATS | | Text Rewriting | Groq llama-3.3-70b-versatile (cloud) | Larger model = better at natural language. Produces find/replace pairs that read naturally | What Gets Modified - ✅ Experience/work bullet points - ✅ Skills/technical skills lines - ❌ Name, contact info, education, dates, company names, job titles — never touched Formatting Preservation The workflow copies your original Google Doc (not recreates it), then uses replaceAllText to swap text in-place. This means: - ✅ Tables, columns, fonts, colors — all preserved - ✅ Bold, italic, underline — all preserved - ✅ Custom spacing, margins — all preserved - ✅ Original doc is untouched (changes go to the copy) --- Setup Steps Prerequisites - Docker installed - Ollama installed locally - A Groq API key (free tier works) - Google account with Docs & Drive access 1.
