Gemini in Chrome vs Comet
An assistant embedded in the browser you already have, versus a full standalone browser — and both are free at their core.
The short answer
- Best for current Chrome usersGemini in Chrome
- Best fully-free agentic browsingComet
- Best on AndroidGemini in Chrome
- Best across all devices (desktop and mobile)Comet
After OpenAI shut down its standalone Atlas browser on August 9, 2026, the question got simpler: if you want free smart browsing today, where do you go? Google is betting on an intelligence layer over the Chrome you already have; Perplexity is betting on a full standalone browser. Both are free at their core, but the philosophy and availability differ fundamentally.
The core difference
Gemini in Chrome is a built-in addition. Nothing to install — it lives inside Chrome itself, summarising pages, answering questions, connected directly to Gmail, Calendar, and Keep. It recently expanded to all US Android users by mid-August 2026, following a gradual rollout that began in May.
Comet is a standalone browser. You install it instead of Chrome (or beside it — it’s Chromium-based and supports the same extensions), and its agentic assistant browses, searches, and fills forms on your behalf — entirely free across Windows, macOS, Android, and iOS since October 2025.
Free agentic browsing favours Comet
This is the sharpest practical difference: Comet Assistant is fully agentic on the free plan, while Gemini’s equivalent — Auto Browse — is reserved for paying Google AI Pro or AI Ultra subscribers. If you want to try real agentic browsing without spending anything, Comet is the obvious route.
Integration and convenience favour Gemini
In return, Gemini in Chrome offers something Comet can’t easily match: zero disruption to your habits. It runs inside your existing Chrome, connects straight to Gmail and Calendar, and can even generate and edit images mid-browsing via Nano Banana — no installs, no migration, nothing new.
Who picks what?
- Already on Chrome, living inside Google? Enable Gemini — a direct gain with zero change.
- Want full agentic browsing with no subscription? Comet — the only free option here.
- On iOS? Comet — the only one with a real standalone Apple-device app.
- Multi-step tasks across tabs for free? Comet Assistant does it without upgrading; Gemini’s Auto Browse doesn’t.

❓ Frequently asked questions
Is Gemini in Chrome actually free?
The core experience, yes — page summarisation, asking questions about what you're viewing, and Gmail/Calendar connections are all free for every Chrome user. But the strongest agentic feature, Auto Browse, which carries out multi-step tasks across tabs on your behalf, is reserved for Google AI Pro (~$20/month) or AI Ultra subscribers.
Is Comet really completely free?
Yes. Perplexity made Comet free for all users on Windows and macOS in October 2025, then removed the last free-tier restrictions worldwide in late July 2026. The free tier includes full agentic browsing through Comet Assistant — paid plans (Comet Plus, Pro, Max) only add higher limits and additional models.
Which is better, in one sentence?
If you already use Chrome and your life lives inside Google's services: turn on Gemini, nothing changes. If you want full agentic browsing with no subscription on any platform (including iOS): Comet.
Are both tied to OpenAI shutting down its Atlas browser?
Indirectly. OpenAI closed its standalone Atlas browser on August 9, 2026 — less than a year after launch — moving its agentic capabilities into the ChatGPT app and a Chrome extension instead. That left Gemini in Chrome and Comet as the two most prominent free options for smart browsing today, each with a different philosophy: a layer over your existing browser, or a full standalone one.
Does agentic browsing preview steps before executing them in both?
Yes, both aim for transparent browsing that shows intent before any consequential action — but personally review anything requesting payment or deletion rights before approving, regardless of the tool.
Can I use Gemini in Chrome without installing anything?
That's precisely the idea — it's part of the Chrome browser itself, so there's no separate extension or desktop app to install. Comet, by contrast, is an entirely separate browser you must install instead of Chrome or alongside it.
Which works better on Apple devices?
Only Comet, which has a full iOS app. Gemini in Chrome currently focuses on desktop Chrome and Android, with no deeply integrated standalone version on Apple devices.
