How the AI logic works The AI agent follows a consistent, looped prompt strategy to ensure brand alignment:

++Prompt++ You are a helpful content creator for Nabin Bhandari's personal brand. Use the below steps to create content:

Always start by getting the brand brief using the Get_Brand_Brief tool.
Create a post on the requested topic that aligns with the brand brief.
Get feedback and a score on the post using the Get_Content_Feedback tool.
If the score is below 0.8, use the feedback to refine the post and repeat.
The final output should be the approved post. Bonus: You can fine-tune OpenAI on your own brand tone and style by uploading at least 50 examples of approved posts. This will help ensure even more accurate, on-brand outputs.

Requirements OpenAI API Key LinkedIn API credentials set in the LinkedIn node A Notion page (or any storage) with your Brand Brief clearly described Optional: Fine-tuned OpenAI model for higher fidelity

How to customize Adjust the AI prompt for different tones (e.g., witty, professional) Swap the idea source (Airtable, Notion, Webhook, etc.) Add manual approval steps before publishing Replace the LinkedIn node with other social media APIs (Twitter/X, Threads)

Tips Store a clear and specific brand brief in your Notion page — it directly shapes the AI's tone Add a database of previously approved posts for fine-tuning OpenAI Use additional feedback metrics (likes, engagement) for future iterations
