LinkedIn Post Generator — Form to Published Post

Writing a single LinkedIn post takes 30–60 minutes — brainstorming a hook, researching the topic, drafting the body, creating a matching image, picking a title, then scheduling. Multiply that by 3 posts a week and consistent posting becomes a part-time job most founders abandon after a month.

A 12-node n8n workflow where you fill out a short form with your topic and three OpenAI agents do the heavy lifting — one writes the post with live web research, one crafts an image prompt, one generates the title. DALL·E renders the image, Google Drive archives it, and Gmail delivers the finished package straight to your inbox.

1. 1📝 On form submission — captures the content idea (topic, audience, angle) via a simple n8n form
2. 2✍️ Create LinkedIn Post Description (AI Agent + OpenAI) — drafts a polished, hook-driven post body
3. 3🔍 Search Web (Tavily tool) — grounds the post in fresh, real research instead of generic AI output
4. 4🎨 Create Image Prompt (AI Agent + OpenAI) — writes a tailored DALL·E prompt to match the post's tone
5. 5🏷️ Generate Title (AI Agent + OpenAI) — crafts a scroll-stopping headline / hook for the post
6. 6🖼️ Generate Image (HTTP → OpenAI DALL·E API) — renders the visual from the AI-generated prompt
7. 7📦 Convert to File — decodes the Base64 image response into an uploadable file binary
8. 8☁️ Upload file (Google Drive) — archives the image to your content library for reuse
9. 9✉️ Send Post (Gmail) — emails the full ready-to-publish package (title + body + image link) to you
