I'm a CTO-turned-solo-founder who got tired of seeing "vibe marketing" success stories (looking at you, Greg Isenberg) without the technical implementation details. So I spent 3 hours building and recording a complete marketing automation system.
*What it does:* - Claude AI analyzes your writing style and generates content - Runs through custom keyword optimization algo - Passes through humanizer algo for authentic voice - Node.js project pushes to Google Sheets for manual approval - Zapier picks up approved content → Buffer schedules it - One command: `npm run generate:weekly` → 2 daily X posts + 3 weekly long-form
*Tech stack:* - Anthropic Claude API for content generation - Custom Node.js algorithms for keyword optimization + humanization - Google Sheets as approval workflow - Zapier for automation workflows - Buffer API for scheduling - Cost: ~$0.15/week (just API calls)
*Architecture decisions:* The Google Sheets approval step was crucial. Pure automation felt too risky for brand voice. Now I can review/edit before publishing while keeping 90% of the workflow automated.
The humanizer algo was the trickiest part - had to fine-tune prompts to maintain my technical writing style while avoiding AI-generated "fluff."
*Why this approach:* Most marketing tools are either expensive ($100+/month) or completely generic. This learns YOUR voice but gives you control over what actually gets published.
*Current workflow:* 1. `npm run generate:weekly` 2. Review Google Sheet, flip approved posts to "confirmed" 3. Everything else happens automatically
*Demo:* I recorded the entire 3-hour build session here: https://x.com/GashiDite/status/1934686143196311841
