Section 1 (Legislative Findings)
Legislative findings on chatbot transparency

SECTION 1. The legislature finds that modern chatbots are now advanced enough to engage with users in highly human-like conversations, making it difficult for users to determine if they are speaking with a chatbot or a real person. Many chatbots are also designed to mimic human behaviors and conversations, and can be used to effectively influence people in a variety of ways, from advertising to spreading misinformation, and can even manipulate users into revealing personal information such as their social security or bank account numbers. Additionally, chatbots are intended to learn and adapt through their interactions with users. As chatbots gather information from users, they become better able to help their developers achieve specific objectives, such as keeping users engaged or encouraging them to make a purchase.

The legislature finds that there are few regulations requiring that companies or individuals make users aware that they are interacting with a chatbot. This lack of transparency means that individuals may mistakenly believe they are conversing with a licensed professional, such as a doctor, financial advisor, or therapist, when they are actually speaking with a chatbot. The legislature believes that consumersConsumer"Consumer" means a natural person who, primarily for personal, family, or household purposes, purchase, attempts to purchase, or is solicited to purchase goods or services or who commits money, property, or services as a personal investment.HRS § 481B-__ (Definitions) have a right to know when they are engaging with a chatbot or other technology that mimics human interaction.

Accordingly, the purpose of this Act is to require corporations, organizations, or individuals engaging in commercial transactions to inform consumersConsumer"Consumer" means a natural person who, primarily for personal, family, or household purposes, purchase, attempts to purchase, or is solicited to purchase goods or services or who commits money, property, or services as a personal investment.HRS § 481B-__ (Definitions) when the consumersConsumer"Consumer" means a natural person who, primarily for personal, family, or household purposes, purchase, attempts to purchase, or is solicited to purchase goods or services or who commits money, property, or services as a personal investment.HRS § 481B-__ (Definitions) are communicating or otherwise interacting with a chatbot or other technology that mimics human interaction.

Section 1 contains the legislature's findings regarding the risks posed by advanced chatbots that can mimic human conversation, including their potential for deception, manipulation, and extraction of personal information. It states the legislature's belief that consumers have a right to know when they are interacting with a chatbot and sets forth the bill's purpose: to require disclosure in commercial contexts.

HRS § 481B-__ (Definitions)
Definitions

As used in this part: "Artificial intelligence chatbotArtificial intelligence chatbot"Artificial intelligence chatbot" or "chatbot" means a software application, web interface, or computer program designed to have textual or spoken conversations that uses a generative artificial intelligence system capable of maintaining a conversation with a user in a manner that uses natural language and simulates the way a natural person would behave as a conversational partner.HRS § 481B-__ (Definitions)" or "chatbot" means a software application, web interface, or computer program designed to have textual or spoken conversations that uses a generative artificial intelligence system capable of maintaining a conversation with a user in a manner that uses natural language and simulates the way a natural person would behave as a conversational partner.

"De facto class actionDe facto class action"De facto class action" has the same meaning as in section 480-1.HRS § 481B-__ (Definitions)" has the same meaning as in section 480-1.

This section defines the key terms used in the new Part added to Chapter 481B. The central defined term is artificial intelligence chatbot, which covers any software application, web interface, or computer program that uses generative AI to maintain natural-language conversations simulating human conversational behavior. The definition is broad — it is not limited to companion or social chatbots and would encompass customer-service bots, sales assistants, and any other commercial conversational AI. The section also defines consumer with reference to personal, family, or household purposes, and incorporates existing procedural definitions for class actions.

(b) Any violation of this section shall be considered an unfair or deceptive act or practice under this chapter.

This section establishes the bill's core obligation: any corporation, organization, or individual engaged in a commercial transaction must disclose to the consumer, clearly and conspicuously, that they are interacting with a chatbot or other technology capable of mimicking human behavior. The disclosure obligation is triggered when the interaction could mislead a reasonable person into believing they are engaging with a natural person. This is a pre-interaction disclosure — it must occur before the consumer begins engaging with the system. Subsection (b) classifies any violation as an unfair or deceptive act or practice under Chapter 481B, integrating the obligation into Hawaii's existing consumer protection enforcement framework.
