AI Post Generator
A workflow built for people who know what they want to say but hate the part where they have to actually write it. You put in a topic, Gemini handles the draft using rules baked into the prompt, and the result lands in a spreadsheet you can come back to anytime. The sheet builds up over time into a full content library, every topic covered, every post generated, all in one place.
The problem
Posting consistently is hard. Not because people don't have things to say, but because going from "I have a thought" to "this is ready to post" takes longer than it should. You sit down to write, spend 20 minutes on an opener, hate it, close the tab, and post nothing.
Most AI writing tools don't fix this. They produce something that sounds like a press release or a LinkedIn influencer trying too hard. You still end up rewriting the whole thing.
What this workflow does
You type a topic. The workflow sends it to Gemini with a prompt that has strict rules baked in: no corporate openers, no hashtag spam, no vague platitudes, no em dashes. The output comes back as clean text.
Then it gets logged. Topic, generated post, and timestamp go straight into Google Sheets. Nothing sits in a JSON response nobody knows how to read. The client gets a growing content library they can actually use.
How it's built
Four nodes.
A manual trigger takes the topic as an input field. An HTTP node sends it to the Gemini API with the prompt as the system instruction. A Set node pulls just the post text out of the response. A Google Sheets node appends the topic, post, and timestamp to the tracker.
The prompt is where most of the work lives. Getting Gemini to consistently write in a natural, human tone without slipping into corporate filler required specific rules, not just a vague instruction to "write like a person."

The result
The output doesn't need editing. That's the actual goal. Not "AI helps you write faster" but "AI writes a solid draft you'd actually post." And every draft lives in a sheet you can come back to.
Posting inconsistently because writing takes too long?
Tell me the platforms, the tone, and how often you want to post. I'll build a workflow that handles the first draft every time and keeps a record of everything generated.
