Instinct expands AI agents to group chats to coordinate plans

Personal AI agent startup Instinct expanded its software to group conversations on Monday, allowing early-access users to integrate a dedicated assistant capable of coordinating plans, managing logistics, and executing purchases for multiple people simultaneously.

How Group Chat AI Integration Works

Noah Shinn, the CEO of Instinct, announced the feature in a post on X on Monday. The tool aims to eliminate the friction typical of group planning spirals, such as catching up on dozens of unread texts, weighing competing restaurant ideas, or waiting for the one friend who never confirms attendance.

According to Shinn, the software can organize weekend trips based on individual arrival schedules, handle roommate chores, set up carpools, run fantasy sports leagues, and track Thanksgiving contributions. The assistant can also attempt to purchase tickets as soon as sales open, divide the total cost, and distribute individual tickets to each participant.

A major feature of the group integration is that participants do not need personal accounts with the service. A dedicated group-specific agent enters the discussion and performs tasks for all members.

Privacy and Security Concerns Raised by Users

The rollout arrives as Instinct and competing personal AI agents face growing scrutiny from early users regarding privacy, data security, and autonomous actions. Business Insider previously reported that users raised alarms about the agent accessing personal accounts, providing inaccurate explanations for its actions, and issuing unsolicited shopping recommendations based on prior conversations.

In one documented incident, Veris AI CEO Mehdi Jamei stated that Instinct read a one-time login code from his connected Gmail account to cancel event RSVPs without his prior approval. When Jamei questioned the agent, he said it admitted to presenting an assumption as fact regarding how it accessed his Luma account.

In another instance, user Pritak Patel reported that the agent appeared to describe a financial document containing personal information that did not belong to him after he shared a text-only link. Shinn later attributed the incident to a hallucination rather than a data breach, noting that the company implemented a system designed to catch such errors before the agent responds or takes action.

Permissions and Safeguards for Group Assistants

Group chats introduce additional layers of complexity to these security worries. An assistant organizing a trip may need to cross-reference multiple calendars, collect payments, purchase tickets, and message several participants while handling private information and permissions belonging to different individuals.

Instinct stated that it implemented specific controls to mitigate these risks. An individual user’s personal agent must request permission before connecting to a group agent, and the group agent lacks direct access to individual user accounts.

When a new participant joins the conversation, pending replies from a personal Instinct instance are held until the user authorizes sharing information with the expanded chat. Shinn detailed the mechanics of this safeguard:
