The bot responds to user queries with word definitions, synonyms, antonyms, and examples, utilizing data from Merriam-Webster's Thesaurus API. The chatbot is integrated with the Twilio API for WhatsApp, allowing users to send messages to the bot via the messaging app. With a virtual environment created using Python 3.6 or newer, Flask, ngrok, and a smartphone with an active phone number, users can test and deploy the chatbot service, which is accessible over the web through a temporary public URL provided by ngrok.
