ChatGPT Atlas vs Comet: Which AI Browser Is Better? Review, Comparisons & More – Mashable India
OpenAI and Perplexity have launched AI-powered web browsers, each aiming to transform daily browsing by embedding their AI assistants directly into the experience. Built on Chromium, both encourage users to rely on their AI rather than traditional search, though they differ in approach and vision for how an AI-first browser should reshape internet usage.
ChatGPT Atlas Vs Perplexity Comet: Feature Comparison
OpenAI’s ChatGPT Atlas is a browser built entirely around ChatGPT, featuring a persistent sidebar that lets users ask questions, summarise content, compare products, and perform analyses. Its standout feature, Agent mode, can automate multi-step tasks like researching trips or shopping. Users control what browsing data is remembered, with default opt-out from training ChatGPT models.
Perplexity’s Comet, on the other hand, combines AI search, summarisation, and task automation within a Chromium-based browser. Users can highlight text, ask follow-up questions, explore tangents without losing context, and manage tabs efficiently. Initially invite-only, Comet went free in October 2025, offering a paid “Plus” tier and Chrome extension support.
ChatGPT Atlas Vs Perplexity Comet: Productivity
Atlas excels for workflow automation and productivity, thanks to its Agent mode and tight ChatGPT integration, which reduces cognitive load and saves time on multi-step tasks. Comet shines for research-intensive and exploration-driven work, allowing users to read multiple articles, branch into tangents, summarise quickly, and stay in context across tabs. It is ideal for quick information consumption, insight discovery, and content-heavy tasks.
ChatGPT Atlas Vs Perplexity Comet: Ecosystem, Cost & Availability
Atlas integrates smoothly for users already accustomed to ChatGPT, but full access to Agent mode requires a paid subscription, and it currently supports macOS only. Comet’s free-tier accessibility makes it attractive to students, independent researchers, and budget-conscious users, while its paid Plus tier unlocks premium features. This makes Comet more approachable for those looking to experiment with AI browsing without upfront costs.
ChatGPT Atlas Vs Perplexity Comet: Security
Comet has raised security concerns in independent audits, including prompt-injection risks and unntended agent actions, which may be problematic for professional or enterprise use. Atlas emphasizes privacy controls and benefits from OpenAI’s enterprise backing, though potential risks remain.
ChatGPT Atlas Vs Perplexity Comet: Conclusion
Overall, Atlas is better suited for users focused on workflow automation and work-critical tasks, while Comet offers a lightweight, free, research-friendly AI browsing experience ideal for students and professionals seeking exploration and summarisation tools.
