A book recommendation SMS bot was built using Programmable SMS with Python and Airtable to store book data. The bot allows users to choose a genre they want to read, and responds with a title of a book by a Black author and a link to a Black-owned bookstore that sells the book. The bot uses an Airtable base to store book data and can be triggered by sending a text message to a specific number. The bot is designed to provide recommendations for anti-racism books, but also includes options for other genres such as poetry and science fiction and fantasy. Users can interact with the bot multiple times, receiving new recommendations each time they send a message.
