However, when you nest loops nodes within loop nodes, item reference becomes difficult to keep track of.\n\nUsing subworkflows, we can break down each loop into a separate execution which handles items and item references in a simpler, linear way. The result is predictable data flow throughout our template. "

Important ideas, decisions, and information get buried in endless message threads and are forgotten by Monday morning.\n\n## The Solution\nAI automatically reviews your group's past week of messages every Monday morning and creates a focused summary report to start the week right.\n\n## How It Works\n1. **Monday 6am**: Automatically collects all group messages from the past week\n2. **Groups messages**: Organizes conversations by user and identifies key discussions\n3. **AI analysis**: Extracts important highlights and observations from the raw messages\n4. **Individual summaries**: Creates focused reports for each team member's contributions\n5. **Team overview**: Combines individual reports into one weekly team summary\n6. **Delivery**: Posts the summary to your WhatsApp group first thing Monday morning\n\n## Best Use Cases\n- Project teams using WhatsApp as their main communication channel\n- Groups where most work discussions happen in one chat\n- Teams that need weekly alignment without endless scroll-back\n\n## Setup Tips\n- Filter for specific team members if you want focused updates\n- Customize the report tone (casual vs formal) based on your audience\n- Works best with active groups that have regular weekly activity\n\n## Requirements\n- WhapAround.pro\n- Gemini AI"
