Generate post ideas with OpenAI, approve your favorite by replying with a number, get 3 AI-written drafts, pick one, and it auto-publishes to LinkedIn - all tracked in Google Sheets.\n\n## How it works\n- Click \"Start Content Cycle\" (or run on a schedule) to generate 10 post ideas tailored to your niche and audience, using an OpenAI-powered agent.\n- The ideas are logged to a Google Sheet and emailed to you.\n- Reply to that email with a number (1-10) to receive 3 full AI-written drafts for that idea.\n- Reply again with a number (1-3) and the chosen draft is published straight to LinkedIn, with every stage tracked in the sheet.\n\n## Setup\n1. Connect your OpenAI account, Gmail account, Google Sheets account and LinkedIn account credentials.\n2. Open the Configuration node and set your niche, audience, notification email and OpenAI model.\n3. Create a Google Sheet with columns: correlationId, stage, niche, audience, ideas, selectedTopic, drafts, linkedinUrn, num_drafts, openai_model, draft_min_words, draft_max_words, linkedin_post_as, linkedin_organization_urn, notification_email. Select it on all 4 Google Sheets nodes.\n4. Select your LinkedIn person or organization on the Publish Post to LinkedIn node.\n\n## Requirements\n- OpenAI account (GPT-5 family)\n- Gmail account (OAuth2)\n- Google Sheets account (OAuth2)\n- LinkedIn account (Community Management OAuth2, for posting as an organization or person)\n\n## Customization\n- Adjust niche, audience, number of ideas/drafts, word count range and OpenAI model in the single Configuration node.\n- Change the Gmail search query on the \"Gmail Trigger - Await Reply\" node if you use a dedicated approvals inbox.\n- Swap the LinkedIn node for a Blotato multi-network post if you want to publish to more than one platform.\n\nNeed help customizing?\nContact me for consulting and support : [Linkedin](https://www.linkedin.com/in/doctor-firass/)\n\n# MY NEW YOUTUBE CHANNEL\n\ud83d\udc49 [Subscribe to my new YouTube channel](https://www.youtube.com/@DrFiras_AI).
