BrightPath Marketing is a made-up agency. ## Step by step 1. ### Start with a chat trigger Create a workflow, add the first step and pick `On chat message`. You talk to the agent here. 2. ### Add the AI Agent and a system message Paste a system message that describes BrightPath Marketing, its audience, its voice and the exact format for each idea. 3. ### Give it a model and memory An OpenAI Chat Model on gpt-5-mini, plus Simple Memory, so "save those" means something. 4. ### Add the Google Sheets tool A sheet called Social Media Ideas with five headers. Set Append Row and let the model fill each column. 5. ### Ask, then say save those Ask for 3 post ideas, then send: Yes, save those ideas to the sheet. It writes one row per idea. Businesses and people in the examples are made up (BrightPath Marketing is a made-up business).
