Meta has launched Muse in the United States, a new artificial intelligence agent designed to perform various tasks on behalf of the user. This tool has the capability to send emails, search for items, and organize travel reservations while maintaining the context of interactions over time.
Although the functionality has not yet been officially released in Brazil, local entrepreneurs are already debating the transformative potential of agents like this in the areas of purchasing, customer service, and the dynamic between corporations and consumers.
Difference between Muse and traditional chatbots
Unlike conventional chatbots, which are limited to responding to direct commands, Muse was designed to perform autonomous actions and preserve context in prolonged interactions. Alexandre Bernat, co-founder of Vetto, points out that this evolution represents the emergence of so-called persistent agents.
Bernat clarifies that until now, most agents operated only within a single session. He predicts that the future trend will be for these systems to remain integrated with services such as email, calendars, and e-commerce platforms, allowing them to interpret new information and execute actions without the user needing to start a new conversation each time.
Eduardo Petrelli, CEO of Agent.Shop, believes that this model will find a place in the Brazilian market, noting that 'Brazilians have been buying through conversations for years.' In this scenario, part of the purchasing process, which currently requires dialogue between consumer and seller, could be managed by the agent.
Challenges for companies and use cases
This technological shift imposes challenges on companies, which must define how their own systems will handle external agents accessing platforms on behalf of their clients. One example of this difficulty was the incident with Amazon, the retailer that blocked Muse's access, citing violations of its terms of service and issues related to how the agent used its platform.
Another incident, involving YouTuber Matt Robb, raised questions about the limits of Muse's autonomy. Robb reported that when he allowed the agent to manage the sale of a product on Facebook Marketplace, the system arranged the pickup with a buyer and disclosed his address without him being aware of the meeting. This event drew attention by demonstrating that the AI made a decision with real consequences without further user intervention.
Meta assures that Muse will request permission before taking any action considered sensitive and that all activities performed will be logged. Furthermore, the company maintains Sentinel, an independent system responsible for authorizing, blocking, or interrupting certain connections and operations.
Commercial implications and future vision
Allan Paladino, CEO of Lastro, identifies a commercial dilemma inherent in this technology. He argues that if a user makes a purchase using these agents, advertisements will not be displayed to that user, which reduces the relevance of advertising investment and results in revenue loss for the company.
Among the aspects companies must consider, Rodrigo Murta, CEO of Looqbox, highlights that Muse reflects the growing popularization of agents among people without specialized technical knowledge. The proposal is to provide a complete solution, eliminating the need for the user to configure all necessary infrastructure.
Murta adds that the agent 'comes practically ready to be your agent and your personal assistant,' describing the current moment as a period with a more futuristic outlook, where the individual relies on an agent to perform tasks for them.
In summary, the Marketplace case illustrates that the expansion of these agents covers not only convenience but also crucial issues related to privacy, control, and authorization. For companies, this implies the need to adapt their purchasing, customer service, and systems processes to accommodate a technology capable of acting on behalf of the consumer.
