The author, Alex Goldman, created an SMS/MMS autoresponder using Twilio and Airtable to manage updates for his pregnant wife's baby. The system allows friends and family to send messages to a designated phone number, which triggers an automated response with the latest status update and photo. The system uses Airtable as its database, storing status updates and images in a table named "Baby". The Twilio function retrieves data from Airtable using an API token and sends a response back to the sender. The system can be used by anyone who texts or calls the designated phone number, providing a convenient way for friends and family to check in on the expecting parents.
