Perplexity's Comet browser is a bet that the browser, not the app, is where AI search gets won

Perplexity's push to grow the user base of Comet, its AI-native web browser, past the early-adopter stage and into mainstream daily-driver territory reflects a strategic conviction that has become widely shared across the AI-search category: whoever controls the browser controls the default surface through which users experience AI-assisted search, shopping and task completion, and that surface-level control is more durable than any individual feature advantage in the underlying model. By building agentic capabilities - autonomous checkout, form-filling, itinerary booking - directly into the browser chrome rather than requiring users to visit a separate website or app, Perplexity is wagering that convenience and habit formation will outweigh Google Chrome's overwhelming existing market share. Google's response has been to accelerate agentic features within Chrome itself, leveraging its existing near-universal browser distribution rather than trying to win new browser-adoption battles the way Perplexity, OpenAI's ChatGPT Atlas browser, and other entrants must. This asymmetry - incumbents extending an existing surface versus challengers trying to win a new one - has defined most of the competitive dynamics in the browser-as-AI-interface category, and history suggests browser-market-share battles favour incumbents overwhelmingly, though the AI-agentic feature set is different enough from prior browser wars that some investors believe genuine disruption is still possible. The monetisation model underlying agentic browsers remains unsettled. Perplexity's subscription-plus-advertising hybrid, OpenAI's tie-in to ChatGPT Plus subscriptions, and Google's ad-revenue-preserving approach through Chrome each represent different bets on how an AI browser eventually generates sustainable revenue once venture subsidy for compute-intensive agentic browsing tapers off, and none has yet demonstrated unit economics that clearly work at scale. For Indian users, who represent one of the largest Chrome user bases globally and have historically been quick adopters of new mobile-first browsing behaviours, the agentic-browser competition is being watched closely by e-commerce and digital-payments companies concerned about what happens to their carefully built checkout funnels if an AI agent increasingly completes transactions on a user's behalf without ever rendering the merchant's actual page. What to watch: whether Comet's user growth curve shows genuine retention beyond initial novelty, how Indian e-commerce platforms adapt their integration strategy if agentic browsing gains meaningful share, and whether any competition regulator scrutinises Google's Chrome-embedded AI features as an extension of its existing search-dominance antitrust exposure.
