AI-Powered LinkedIn Content Engine (n8n + OpenAI + Perplexity + Replicate)

🧠 OpenAI – Content Creation Support

This is one of the core nodes of the workflow. It generates the actual LinkedIn post based on the topic you selected and the insights retrieved earlier.

Here, you can review and personalize the prompt to reflect your personal information, tone of voice, and the desired output language (currently set to Italian for my audience).

⚙️ Setup Required

You’ll need an OpenAI API key (note: this is different from a ChatGPT account)

⚠️ API calls have a cost, so choose your model wisely
→ I suggest balancing performance and price — you're writing a LinkedIn post, not launching a rocket 🚀

✏️ How to Personalize

Open the prompt inside the node and replace my personal details with your own

You can customize:

The writing style (e.g., tone, use of emojis, structure)

The language of the output

For an extra check, paste the prompt into ChatGPT and refine it there based on your style
