What can an AI browser do that a normal browser can't?
An AI browser adds an assistant that understands the pages you're on: it can summarize an article, answer questions across all your open tabs, research a topic, and — in agentic browsers like Comet, Opera Neon, and Fellou — actually complete tasks such as filling forms, gathering data, or booking things for you. A normal browser just displays pages; an AI browser reads, reasons about, and increasingly acts on them, shifting you from doing the clicking to directing the work.
Is Perplexity Comet worth switching to?
For research-heavy and information work, it's the most capable AI browser in 2026 and it's free, so it's well worth trialing as a second browser. Whether to fully switch depends on how much you rely on your current browser's extensions, saved logins, and workflow — the practical approach is to run Comet alongside your main browser for a couple of weeks on real tasks and let its agentic search and summaries prove (or not) that they save you enough time to justify moving over.
Do I need a new browser, or can I add AI to the one I use?
You can often just add AI to what you have — Chrome now includes Gemini and Edge includes Copilot, giving you summaries and chat without switching, which is the lowest-friction option for most people. Switch to an AI-native browser (Comet, Dia, Opera Neon) when you want deeper, agentic capabilities those built-in assistants don't yet match. Start with the AI in your current browser, and move to a dedicated one only if you hit its limits.
Are AI browsers safe, given they can see everything I do?
That's the key concern: a browser sees your logins, messages, and everything you view, and an agentic one may take actions on your behalf — so privacy and oversight matter a lot. Read the browser's data-handling terms, be cautious about letting an agent handle sensitive actions like payments or logins unsupervised, and prefer privacy-focused options like Brave if that's your priority. Treat an AI browser's permissions the way you would a powerful assistant's: useful, but worth watching.
What's an 'agentic' browser?
An agentic browser doesn't just answer questions about pages — it takes multi-step actions to complete a goal, like navigating sites, filling forms, comparing options, and carrying out a booking or purchase for you. Comet, Opera Neon, and Fellou lead here, while built-in assistants like Chrome's Gemini are moving in that direction. Agentic browsing is the most powerful and least mature capability in the category, so it's genuinely useful for repetitive web tasks but should be supervised on anything consequential.
