The Hook Factory: 5 Prompt Angles I Automated in n8n (Steal the System)

Description and use

An n8n workflow automates the creation of five hook variants per post, cutting creation time from 20 minutes to 12 seconds and improving engagement.

Problem

Content creators spend a disproportionate amount of time crafting the first two lines of a post, the hook, which determines reader engagement.

Outcome

The workflow produces five hook variants—Curiosity gap, Contrarian take, Specific number, Micro‑story, Direct callout—per post, with a 12‑second run time and under a cent cost per batch. Two hooks outperformed the rest of the series combined on comments.

Workflow

• Set node: input post topic
• Parallel branches: five LLM calls, each with its own system instruction and two few‑shot examples
• Merge node: Code node assembles strict JSON output
• Dedup guard: reject hooks sharing >60% content words, re‑run once
• Human selection: pick best hook

Evidence

I tracked it for a month: on a typical 800-word post, I spent 40% of the time on the hook and 60% on everything else.

The workflow runs on my laptop's n8n before I write a single word of the article. Twenty minutes of staring, replaced by a 12-second run and a 2-minute pick-the-best.
