PR Newswire·medium signal

PolyAI released its Agent Development Kit (ADK) on April 22, enabling developer teams to build CX agents in their preferred IDE/language with full codebase visibility, version control, and code reviews — the opposite of closed-system CX AI vendors. The ADK includes self-learning loops where agents identify performance gaps and continuously improve via automated QA pipelines. Enterprise customers include Marriott, Caesars Entertainment, PG&E, and UniCredit.
