Modern organisations are inundated with information. Browser windows are cluttered with dozens of tabs, research tasks span multiple websites and documents, and decision‑makers often juggle e‑mails, calendars and presentations while trying to find reliable data. Perplexity AI's Comet browser aims to solve these issues by reimagining the browser as an intelligent assistant that thinks alongside you.
Unlike traditional browsers that simply display web pages, Comet combines Perplexity's LLM‑powered answer engine with agentic AI modules to deliver real‑time research, personalised insights and task automation directly within your browsing experience. Built on Chromium, it supports existing Chrome extensions and imports bookmarks, passwords and settings with one click. What makes Comet unique is its local‑first design: browsing data, search histories and AI queries are stored on the user's device, without telemetry being sent to Perplexity. For businesses this means access to advanced AI while retaining data ownership.
What Makes Comet Different? The Shift From Navigation to Cognition
Perplexity describes Comet as a browser built for "navigation to cognition." The side‑panel assistant isn't just a chatbot; it understands page context across tabs, can summarise articles or videos, compare products and even draft e‑mails or schedule meetings. Early adopters gained access in July 2025 through Perplexity's Max plan, with investors like NVIDIA and SoftBank backing the venture.
Unlike some AI integrations that bolt onto existing browsers, Comet integrates Perplexity's proprietary search engine and agentic modules at the core, delivering citation‑backed answers and tasks without leaving your current page.
Comet Assistant vs. Comet Agent
Comet Assistant
- Persistent sidebar that analyses content
- Answers questions and summarises documents
- Provides context across tabs
Comet Agent
- Autonomously fills out forms and makes purchases
- Books flights and schedules meetings
- Integrates with Gmail, Calendar, and Drive
Comet actually houses two AI personalities. Comet Assistant is the persistent sidebar that analyses content, answers questions, summarises documents and provides context across tabs. Comet Agent, available to paying users, goes further: it can autonomously fill out forms, make purchases, book flights, schedule meetings, draft e‑mails and integrate with services like Gmail, Google Calendar and Drive. The assistant helps you understand and organise information; the agent executes multi‑step workflows and acts as a delegated "chief‑of‑staff."
Core Features for Business Users
To understand Comet's value proposition for enterprises, consider its key capabilities:
AI‑First Search and Summarisation
Comet's default search uses Perplexity's answer engine to generate concise, citation‑backed summaries without opening new tabs. Highlight any text, PDF, or video and press Alt + S to generate an instant summary.
Contextual Side‑Panel Assistant
The assistant has cross‑tab awareness and can read the content of open tabs to answer questions, compare products and extract insights. It can summarise YouTube videos, PDFs and social media posts without copying or pasting.
Task Automation
Through Comet Agent, you can draft e‑mails, schedule meetings, purchase items, autofill forms and even book travel. These functions integrate with Gmail, Google Calendar and Google Drive via secure OAuth permissions.
Voice Mode and Smart Tab Management
Press Alt + Shift + V to interact with the assistant hands‑free, ideal for multitasking or accessibility. Comet organises tabs by topic, closes duplicates and creates colour‑coded collections while preserving context across sessions.
Enterprise Integrations
For Perplexity Enterprise customers, Comet surfaces answers from internal files and knowledge bases while maintaining compliance with SOC 2, GDPR and HIPAA. User management features like SSO and audit logs provide governance.
Productivity and Operational Benefits for Businesses
1. Accelerated Research and Decision‑Making
Traditional research involves opening multiple tabs, scanning long articles and cross‑checking information. Comet's AI‑first search returns concise answers with citations, enabling executives to quickly grasp issues and follow up with deeper questions. The assistant can run comparative analyses of competitors or summarise market reports across tabs, saving hours of manual reading.
2. Enhanced Productivity Through Task Delegation
Comet Agent automates routine tasks like e‑mail drafting, calendar management and form filling. Instead of toggling between Gmail and your calendar, you can instruct Comet to "schedule a meeting next Tuesday at 10 AM with the sales team" and it will handle the logistics. Background assistants can execute several tasks in parallel, such as ordering supplies while generating a market report.
3. Contextual Insights Across Tabs
Busy professionals often lose context when switching between research articles, CRM systems and spreadsheets. Comet remembers what you viewed and allows cross‑tab referencing, enabling statements like "Compare the pricing on tab 3 with the specifications on tab 5." This reduces duplication and ensures insights are grounded in the latest data.
4. Integrated Knowledge Management
Comet can connect to internal knowledge repositories via Perplexity Enterprise to search across company files, knowledge bases and wikis. This unifies external web research with internal data, giving employees a single interface to query both sources and generate charts or analyses.
5. Reduced Cognitive Load
Smart tab management organises tabs, reduces clutter and groups related content. Voice mode allows hands‑free interactions so executives can continue reviewing documents while requesting a summary. These small design choices reduce friction and free mental bandwidth.
Risks, Security and Governance Considerations
⚠️ Agentic Browsing Vulnerabilities
In August 2025, security researchers discovered an indirect prompt injection vulnerability in Comet. Brave's research demonstrated that when the assistant summarises a webpage, it can inadvertently execute hidden instructions embedded in the page. Attackers could hide text in HTML comments or white‑on‑white fonts; when the user asks for a summary, the AI processes the malicious instructions and follows them.
The proof‑of‑concept showed that hidden commands could instruct Comet to navigate to the user's email, retrieve an OTP and exfiltrate sensitive data. The attack exploited the AI's inability to distinguish between user requests and untrusted page content and bypassed traditional web security mechanisms like same‑origin policy.
🔒 Privacy and Data Access Concerns
Comet requires broad access to data to function effectively. The browser can search through your history, documents and local files; it can read content from open tabs to provide context; and it can connect to Gmail and Calendar to draft e‑mails and schedule meetings. In corporate environments, this level of access to proprietary information, client data and intellectual property could be risky if not governed carefully.
🛡️ Governance and Best Practices
Security Measures:
- • Implement Role‑Based Permissions
- • Educate Employees on Safe Browsing

Real‑World Business Use Cases
Sales and Customer Success
Comet can summarise client communications, extract action items and draft personalised follow‑ups. Sales teams researching prospects can use the assistant to compile information from websites, social media and internal CRM notes, then generate a call script or proposal.
Market and Competitive Research
Analysts can ask Comet to compare competitors' product specs across multiple tabs, summarise analyst reports and track industry trends without switching between sources. One click summarisation of white papers or research PDFs accelerates due diligence.
Product Development and R&D
Engineers can have Comet summarise technical documentation, API references and user feedback, then generate meeting notes or backlog items. Voice mode allows note‑taking while reviewing code documentation.
Finance and Strategy
CFOs or analysts can ask the assistant to summarise earnings reports, create ratio analyses and visualise data using the enterprise platform's charting features. The agent could even retrieve transactions from banking portals and compile expense summaries.

Final Thoughts: Harnessing AI Browsing Responsibly
Perplexity's Comet browser embodies a bold vision: to turn everyday browsing into a cognitive, assistant‑driven experience. For businesses, it offers a single interface that merges external research, internal knowledge and task automation, promising significant productivity gains and better decision‑making. The ability to summarise complex documents, draw insights across tabs, and delegate repetitive work can free employees to focus on strategy and creativity.
Yet, with great power comes great responsibility. Comet's agentic features and deep data access create new security and privacy challenges. Recent vulnerabilities—such as prompt injection and CometJacking—show how malicious actors can exploit AI tools to exfiltrate data. Moreover, the continuous processing of local files, open tabs and enterprise systems raises concerns about confidentiality.
Enterprises exploring Comet should implement robust governance: limit permissions, educate users, monitor agent activity and conduct regular security assessments. Used judiciously, Comet can be a powerful AI productivity assistant that transforms how organisations research, communicate and act. By balancing innovation with caution, businesses can harness this AI browser for business to accelerate growth while safeguarding their most valuable assets.
