Statutory Text
Analysis & Obligations
Section 1 (Legislative Findings)
Legislative findings on AI chatbot risks

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 further 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.§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: (1) 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.§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.§481B-__ (Definitions) are communicating or otherwise interacting with a chatbot or other technology that mimics human interaction; and (2) Developers of chatbots that sell, offer for sale, advertise, or make available chatbots to disclose that their chatbots use artificial intelligence and are capable of mimicking human behavior and engaging in a textual or spoken conversation.

Section 1 sets out the legislature's findings regarding the risks of advanced chatbots that can mimic human conversation, including deception, manipulation, extraction of personal information, and the lack of existing transparency requirements. These are purely declaratory and create no compliance obligations.

§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.§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.

"Class actionClass action"Class action" includes the definition as provided in rule 23 of the Hawaii rules of civil procedure.§481B-__ (Definitions)" includes the definition as provided in rule 23 of the Hawaii rules of civil procedure.

"ConsumerConsumer"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.§481B-__ (Definitions)" 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.

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

This section establishes the key defined terms for the new part, including artificial intelligence chatbot (or chatbot) and consumer. The chatbot definition is broad: any software application, web interface, or computer program that uses generative AI to carry on natural-language conversations simulating a human conversational partner. Notably, the definition is not limited to companion or social chatbots — it covers any generative-AI-powered conversational interface. The consumer definition tracks standard consumer-protection usage, covering natural persons acting for personal, family, or household purposes.

(b) 2 No developer of an 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.§481B-__ (Definitions) shall sell, offer for sale, advertise, or make available any 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.§481B-__ (Definitions) without disclosing in a clear and conspicuous fashion that the chatbot uses artificial intelligence and is capable of mimicking human behavior and engaging in a textual or spoken conversation with a person in a manner that may mislead or deceive a reasonable person to believe they are engaging with a natural person.

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

This is the bill's core operative section. It imposes two distinct disclosure obligations on two different actor types. Subsection (a) targets any corporation, organization, or individual engaged in a commercial transaction who uses a chatbot: they must provide clear and conspicuous notice to consumers before the consumer interacts with the chatbot, whenever the interaction could mislead a reasonable person into believing they are engaging with a natural person. A small-business safe harbor applies when the small business unknowingly uses AI chatbots and has not received clear notice of these requirements. Subsection (b) targets developers who sell, offer for sale, advertise, or make available chatbots: they must disclose that the chatbot uses artificial intelligence and is capable of mimicking human behavior. Subsection (c) designates any violation as an unfair or deceptive act or practice under Chapter 481B.
