The Challenge
Marketing teams often face a “content treadmill”—the constant need for fresh, high-quality posts. Existing SaaS solutions are expensive and often compromise data privacy by sending internal strategy to third-party cloud APIs.
The Solution
I engineered a local-first automation stack that handles everything from trend research to asset generation. By using n8n as the orchestrator and LM Studio for local inference, the system generates brand-aligned copy and visuals without a single cent in API fees.
Key Architecture
- Orchestration: n8n running via Docker on a local server.
- Inference: Meta-Llama-3.1-8B (Quantized) for high-speed copywriting.
- Visuals: ComfyUI with SDXL for generating contextually relevant post images.
- Deployment: Automated triggers for LinkedIn and Instagram via webhooks.
The Impact
The system reduced content creation time by 90%, allowing for a consistent daily posting schedule while maintaining 100% data sovereignty.
