What is texting chacha?

ChaCha was a text message-based question-and-answer service that operated from 2006 until 2016. Users could text any question to the ChaCha number and within minutes receive an answer from a live human guide. The service was free, but sometimes text messaging fees applied depending on the user's plan. ChaCha had over 20 million unique monthly users at its peak and answered over 2 billion questions during its operation. In 2016, ChaCha discontinued its text message-based service and rebranded as a mobile app for sharing and discovering stories.
