Introduction

For most of us, a browser has always been a passive tool: you open tabs, you type, you click, you read. The web waits for you to do the work. That assumption is what AI browsers like Comet and Dia are quietly dismantling. Instead of only helping you navigate pages, these AI browsers can read open tabs, summarise documents and, in some cases, complete multi-step tasks on your behalf.

That shift matters in India because the country's internet audience is still expanding, bringing more people and more everyday activity onto the web. The IAMAI and Kantar Internet in India Report 2025 recorded 958 million active internet users in 2025, with 57% coming from rural India. With such a large and diverse internet audience, bringing AI into the browser could put capabilities such as research, information processing and task automation within reach of people who may not seek out a standalone AI tool.

This piece breaks down what AI browsers actually do, how Comet and Dia differ, and where the trade-offs sit for students and young workers who live inside tabs all day.

What Are AI Browsers?

An AI browser integrates AI directly into the browsing experience, allowing you to ask questions about webpages, tabs or browsing context and, in some cases, ask the browser to perform actions for you. Both Comet and Dia are built on Chromium, which means existing websites render normally; the intelligence is a layer sitting on top, not a new engine underneath.

Comet, from Perplexity, combines web browsing with an AI assistant that can understand the page you're viewing, work across tabs and carry out multi-step tasks such as filling forms or comparing information. Dia, from The Browser Company, turns its URL bar into a chat interface that can summarise uploaded files, answer questions about every open tab, and switch between search and chat automatically. That is a meaningful reframing: the same box you once used only to type a web address now doubles as a research assistant that can work with the information in your tabs.

This is why the market treats them as a "layer" rather than a replacement. Analysis citing StatCounter data notes that Google Chrome still holds over 90% usage in India (last verified 2025). Habits like tabs, bookmarks and the omnibox are deeply set, so AI browsers compete on assistance, not on rendering speed.

Comet vs Dia: Two Different Ideas of Navigation

It is tempting to lump the two together, but they represent two distinct philosophies of what an AI browser should do. Dia leans chat-first: it wants to help you read, understand and write faster. Comet leans agentic: it wants to act.

Comparative coverage describes Comet's agent mode as able to book restaurant tables, purchase items, fill web forms and respond to emails, all from inside the browser. The assistant understands which tab is active and can run multi-step flows. Dia, by contrast, focuses on inline writing tools, per-user tone preferences, and an optional seven-day browsing memory that stays off by default.

The pricing shift is worth noting. Comet initially launched in July 2025 tied to a paid tier, then became free globally by 2 October 2025, while Dia keeps advanced Skills behind a Pro plan. For a student weighing which to try, that free tier removes the first barrier to experimenting with agentic browsing.

Why This Shift Matters in India Now

The reason this is not just a Silicon Valley story is the composition of who is coming online. The Kantar and IAMAI research highlights rising rural adoption and a narrowing gender gap, with the country remaining overwhelmingly mobile-first. A large share of users are accustomed to accessing digital services through app-based experiences rather than traditional desktop browsing. AI browsers bring a more conversational and task-oriented way of interacting with the web, creating an interesting shift as more of these users move between apps and browser-based services.

India's internet growth is also changing what people do online. As more users rely on the web for research, shopping, applications, education and everyday services, the number of tasks performed through a browser continues to expand. AI browsers are designed around exactly these workflows, combining information retrieval with actions that users would otherwise perform manually.

The opportunity is not simply about finding information faster. Price comparisons, form filling, research and reading long documents can involve multiple tabs and repeated manual steps. Agentic browsers target this layer of work by combining information from different pages with the ability to take actions on the user's behalf.

What Changes for Students and Early Careers

Consider a familiar scene: a student compiling notes from six research papers, a couple of YouTube transcripts and a Wikipedia entry. In a traditional browser, that means constant tab switching and manual copy-paste. Dia's ability to answer questions across all open tabs collapses that into a single conversation with the material already loaded.

For someone applying to jobs or internships, Comet's form-filling capabilities change a different chore. Repetitive application forms, the sort of task that eats an evening, become something the browser can handle while you supervise. The catch is judgement. An assistant that reads and acts is only as reliable as your ability to verify what it produces. Summaries can flatten nuance; agentic actions can misread intent. The skill that matters now is not typing faster; it is checking outputs well.

What to Weigh Before You Switch

Adopting an AI browser is a genuine trade-off, not a free upgrade. A few realities are worth holding in view before you make it your default.

• Privacy: AI browsers may process information from the pages, tabs and actions they can access. Check what each browser stores, what it sends to its servers and which permissions you grant.
• Verification load: the more the browser acts, the more you carry responsibility for checking. Automation shifts effort; it does not remove it.
• Cost: Some AI browsers and advanced features operate on paid plans, so check what is included in the free version before switching.
• Habit inertia: Your existing bookmarks, extensions, saved passwords and browsing habits may be tied to your current browser. Switching can involve more friction than simply installing a new app.

The right choice depends on what you want the browser to do. If you regularly research, compare information or handle repetitive web tasks, the added automation may justify the switch. If you mainly browse, read and use established extensions, the benefits may not outweigh the disruption of changing browsers.

Conclusion

FAQ

Can AI browsers search my browsing history?

Yes. Comet can search your browsing history, videos and documents to help find information you viewed previously. Dia can also use your browser history and built-in Memory to provide context from your previous activity.

Can I use an AI browser on my phone?

Some can, depending on the browser. Mobile availability varies by product, so check whether the AI browser you want to use has an official iOS or Android version.

Can AI browsers use my existing bookmarks and extensions?

Yes. Comet can import browser data such as bookmarks, passwords, browsing history and extensions, although the available import options vary by browser. Dia also supports importing bookmarks, extensions, passwords and history from browsers including Chrome, Safari, Edge and Arc.

Can AI browsers work with PDFs and other documents?

Yes. Some AI browsers can analyse documents directly within the browser. For example, Dia can summarise files you upload, allowing you to work with their contents without opening a separate AI tool.
