Today, October 21, 2025, OpenAI launched its Atlas browser. The result? Alphabet stock: -4%.
Together with Perplexity’s Comet and The Browser Company’s Dia, we now have three AI-native browsers challenging Chrome’s 3-billion-user dominance.
What makes these browsers so different?
🔹 COMET (Perplexity): The Automator
Multi-LLM access (GPT, Claude, Gemini, Grok, Sonar)
Agentic AI that independently writes emails, manages calendars, fills forms
$200/month for Max features, basic free
⚠️ Warning: CometJacking security vulnerability discovered
🔹 DIA (Browser Company/Atlassian): The Synthesizer
Acquired today for $610M by Atlassian
Focus on cross-tab intelligence over automation
Skills system for custom workflows
$20/month
🔹 ATLAS (OpenAI): The Conversationalist & Agent
Launched today, macOS-only (Windows coming)
Free, Agent mode for $20/month Plus subscribers
ChatGPT integration in every tab
800M+ potential users
The Paradigm Shift
These browsers aren’t Chrome clones with AI sidebars. They’re built from the ground up around conversation and agents.
Instead of “Go to website X” → “Find the best laptops under $1500, compare reviews, and show me the 3 best deals”
The browser does everything – autonomously.
For Business Users: Opportunities & Risks
✅ Productivity gains: Comet users ask 6-18x more on day one
✅ 40-minute videos summarized in 5 seconds
✅ Multi-source research synthesized across 15 tabs
⚠️ Security risks: CometJacking demonstrated exploits
⚠️ Privacy trade-offs: Comprehensive data access required
⚠️ Reliability problems: Hallucinations in complex tasks
My Recommendation
Now: Pilot programs with small teams and in private at home.
Not yet: Enterprise-wide rollout.
Wait for:
– Enterprise security features
– Cross-platform maturity
– Clear GDPR compliance
My Prediction for the next 12 Months:
Chrome will integrate Gemini deeper. Edge will expand Copilot. Safari might announce Perplexity partnership.
The feature parity race has begun.
The Bigger Question
The real question is: Whose AI do you trust most?
Google (with controversial ad-tracking history)? OpenAI (relatively new, profit pressure)? Perplexity (startup with exit incentives)? Atlassian (enterprise focus)?
What do you think: Is it time to leave Chrome behind? Or overhyped tech trend?
