Citibot

Citibot is an AI resident-engagement assistant for local government, handling 311 requests, service requests, bill payment, and emergency alerts over text message, web chat, and voice in more than 75 languages, across channels including SMS, web, phone, Facebook Messenger, and WhatsApp.

Citibot's most visible deployment powers Denver's resident assistant, 'Sunny.' The company reports that Sunny has engaged more than 95,000 residents, answered over 100,000 questions, and filed more than 5,000 service-request cases across 72 languages.

Citibot is a private company that is smaller and less capitalized than some competitors such as Polimorphic. Its scale metrics come from a single flagship deployment and are self-reported, and benefits or eligibility chatbots carry hallucination and accessibility-equity risks that call for human review.
