Automated Daily WhatsApp Group Summaries with Custom Controls

The workflow is divided into two parts: message capture and storage, and summary generation and delivery. It begins by receiving messages via a webhook from the Evolution API, identifying whether they are from a group or an individual, and distinguishing between text and audio messages. Audio messages are transcribed using OpenAI. All messages are stored in a Google Sheet, organized by group, sender, timestamp, and message content. A control panel in the Google Sheet allows users to enable or disable summaries for each group. Every morning, the workflow collects messages from the previous day, groups them by chat, and sends them to OpenAI to generate a summary, which is then delivered to the respective WhatsApp groups.
