I built a system that writes, images, and schedules my LinkedIn + Contra posts every day automatically.

Here's exactly how it works:

Every morning at 8am it: → Searches the web for what's trending in AI and automation (Tavily) → Picks the best topic based on my past posts (no duplicates) → Researches it with a live deep-dive → Drafts two versions — one for LinkedIn, one for Contra — using Claude Sonnet 4.6 → Generates a branded image card → Emails me a preview to review → Posts automatically once I approve

Total running cost: $1.57/month

The stack I used:

n8n (self-hosted workflow engine)

Claude Sonnet 4.6 — post drafting and rewriting

Tavily API — real-time trend research

Google Sheets — content calendar, idea bank, post log

HCTI — branded image cards

Kie AI — AI-generated visuals

Gmail OAuth2 — daily preview emails

The whole thing runs on Docker on my local machine. Zero monthly SaaS fees. I still review every post before it goes live — the system handles the research, writing, and scheduling.

If you're a founder or business spending hours on content every week, this is the kind of automation I build.
