It has also added clear buttons to stop Comet Assistant or provide more guidance. The San Francisco-based AI startup said that these upgrades to Comet Assistant have been made in line with three core principles, namely: Transparency, user control, and sound judgment.“Every improvement to the Comet Assistant advances these principles. It now shows you exactly what it’s doing, asks how you want it to act, and demonstrates sound judgment before completing sensitive actions,” Perplexity said.The Perplexity Search or omnibar has also been upgraded so that users can more easily choose whether they want to browse the web, allow Comet Assistant to browse on their behalf once, or let the Assistant automatically browse for users when it detects the chance to be useful.Comet Assistant’s new features come at a time when AI startups are racing to build AI-powered browsers in an attempt to boost user reach and distribution. However, the rise of AI browser agents has led to data privacy and security concerns.Story continues below this adAlso Read | Perplexity’s AI browser ‘Comet’ coming to Android: Follow these steps for early accessResearchers have pointed out that agentic AI browsers such as Perplexity’s Comet and OpenAI’s ChatGPT Atlas could allow attackers to maliciously instruct the browser agent via indirect prompt injection and gain access to sensitive user data, including emails, banking passwords, and other personal information.OpenAI itself has acknowledged the possibility of such an attack. “Besides simply making mistakes when acting on your behalf, agents are susceptible to hidden malicious instructions, which may be hidden in places such as a webpage or email with the intention that the instructions override ChatGPT agent’s intended behaviour. This could lead to stealing data from sites you’re logged into or taking actions you didn’t intend,” the ChatGPT-maker has previously said.However, firms like Perplexity have continued to insist that users will always be in control of AI browser agents. “By prioritising visibility, adapting to your preferences, and requesting permission before sensitive actions, the Comet Assistant works at the speed of autonomy while keeping you firmly in control,” the company said.Recently, Perplexity said it has upgraded Comet Assistant with the ability to switch back and forth between tabs in order to fill out a spreadsheet or for other data entry-related tasks. It also made adjustments to the AI browser agent’s underlying architecture, enabling it to better perceive and interact with complex web environments. The $20 billion-dollar Google challenger also said it will be launching a new AI assistant in the coming days.© IE Online Media Services Pvt LtdTags:artificial intelligencePerplexity
