However, we structured this template a bit differently. The goal: give end-users more control over the AI-generated content.\n\nThis template is designed to serve as the backbone of a UI built with an app builder like WeWeb. The interface includes three screens:\n1. Create topics\n2. Edit topics and generate posts\n3. Edit posts and generate images\n\nEach screen has its own dedicated webhook. This ensures users are 100% in control of the content that’s generated and published to their LinkedIn account.\n\nIf you'd like to connect this n8n template directly to a WeWeb UI, it's possible. The WeWeb template is available for free [right here](https://go.weweb.io/zoYeg5g). "
