The Explosive Emergence and Announced Fall of Agentic Browsing.
The ambitious entry of Perplexity AI into the web browser market can be said to be having an untimely end and with a legitimate source of information, the company is about to sunset its “Comet” browser less than a year after it was launched in high mayhe. A promises-to-redefine internet navigation, Comet was set to be released in July 2025, and was meant to redefine the passive browsing behavior to an active, automated act. But, according to some sources, who are close to the company, even though the initial hype was high, the number of daily active users has stalled way below the internal expectations. The browser that was labeled as a Google Chrome killer has been reported to have difficulty in maintaining the users who believed that the interface that seemed heavy on AI was slow in comparison with the established ones.

Litigation and Business Backlash Kill Expansion.
One of the reasons that have brought Comet to its knees has been vehement legal and technical opposition by large digital platforms. In November 2025, Amazon sued Perplexity, claiming that autonomous shopping agents of Comet were not using normal user interfaces to retrieve data and make unauthorized purchases. This court battle had hit the core of the Comet product offering, which was to enable the user do things on his/her behalf and this included purchasing products or booking tickets automatically. Other large e-commerce market actors, under the influence of the cease-and-desist order issued by Amazon, reportedly put technical blocks to make the agents of Comet unable to enter their websites. These limitations essentially gutted the flagship capabilities of the browser leaving users with an extremely heavy and resource-hungry application that was unable to execute the functions that the browser was marketed to do.
User Trust Undermined by Critical Security Flaws.
Adding to the legal woes is the fact that the browser has been facing some major security issues since the end of 2025. A devastating report by cybersecurity company SquareX disclosed a so-called zero-click vulnerability of the Comet architecture that may enable malicious participants to erase files in a Google Drive of a user just by sending a specially designed e-mail. Despite the fact that Perplexity took the necessary step to repair these vulnerabilities, the damage to the reputation was extensive. Enterprise clients, among the most important sources of revenue to Perplexity has been reputedly reluctant to install a browser which legitimizes an AI agent such substantial, unmonitored access to local files and cloud storage. The fear of being attacked by the hackers using AI as a tool to execute malicious code has kept the browser out of the business sectors it was meant to provide services to.
Performance Fatigues and Subscription Fatigue.
On top of this drama of high stakes lawsuits and hackers, the every-day customer experience of Comet has apparently not been up to par. As free alternatives such as Google Chrome and Microsoft Edge have begun to add their own less expensive AI capabilities of their own at no cost, the business case of a premium, stand-alone AI browser has become more and more challenging to sell to the average consumer.
A Tactical Remodelling Back to the Basics Search.
Comet has been a prospective closure of the company indicating a wider strategic turn of Perplexity in trying to establish itself in the competitive AI search industry. Analysts believe that the company is probably to drop the standalone browser and concentrate resources on their main search engine and other lighter browser extensions that have less maintenance burden and risk of legal liability. Abdicating a dedicated browser application will allow Perplexity to escape the direct conflict with browser giants without necessarily sacrificing its ability to provide users with its AI features. Should the shutdown be verified, it would be a great setback to the business, acting as a warning of the challenge of replacing established infrastructure software such as web browsers, despite having a better AI technology.
