Perplexity Comet
Gemini in Chrome
The only one of the three that runs on every major platform and lets admins restrict agent actions to approved domains, at a free entry price
No migration for Chrome shops, and the most conservative checkpoints: Gemini prepares, you press buy or post
- Desktop + mobile
- Domain-limited actions
- MDM install
- Free browser
- Built into Chrome
- Human checkpoints
- Separate agent tab
- New browser to support
- 2025 injection disclosure
- US only
- Needs AI Pro or Ultra
Key Takeaways
- Perplexity Comet — A separate browser, free, on desktop, Android and iOS. Comet Enterprise adds MDM deployment and can limit agent actions to approved domains or switch them off.
- Gemini in Chrome — Auto browse arrived January 28, 2026. It works in a marked tab, leaves the buy and post buttons to you, and needs Google AI Pro ($20/mo) or Ultra ($100/mo) in the US.
- Claude in Chrome — A Chrome extension, generally available August 26, 2026 on paid Claude plans. A safety classifier checks each action; Team and Enterprise admins set site allow-lists and block-lists.
- Bottom line — Comet for a governed, standalone agent browser. Gemini if you are a Chrome shop that wants the most conservative checkpoints. Claude if your team already works in Claude.
Three designs for the same job
All three let an AI agent work through websites for you. They differ in where the agent lives and how much it is allowed to do alone. Comet is a whole browser built around Perplexity's agent. Gemini in Chrome adds an agent to the browser most companies already manage, and keeps the final click with the person. Claude in Chrome is an extension that, since general availability in August 2026, lets a safety classifier approve actions instead of the user.
Those design choices matter more than feature lists, because an agent in a browser acts with your logins. Text on any page can try to steer it. Gartner advised blocking AI browsers in December 2025, and the controls compared below are what make a narrower policy possible. Facts verified against vendor announcements and coverage through October 31, 2026.

Perplexity Comet
Comet launched on desktop in July 2025, became free for everyone that autumn, and reached Android in November 2025 and iOS in March 2026. Its enterprise build, announced in March 2026, adds a silent installer for MDM tools and lets admins permit answers without actions, or actions only on approved domains.
Perplexity Comet
- Runs everywhere, including iOS and Android, so one policy covers desktop and mobile
- Free browser, so a pilot costs nothing up front
- Comet Enterprise can restrict agent actions to approved domains or turn actions off entirely
- A new browser to roll out, patch and support
- Brave's 2025 disclosure showed an injection chain; ask what changed in your security review
Gemini in Chrome
Auto browse launched on January 28, 2026 for Google AI Pro and Ultra subscribers in the US. Gemini opens a marked tab, works through the task while you browse elsewhere, and shows its steps in the side panel. It will not press buy or post for you, password autofill needs your approval, and a daily action limit applies.
Gemini in Chrome
- No browser migration for Chrome shops
- The most conservative checkpoints: buy and post stay with the user, autofill needs approval
- Agent work happens in a separate tab you can watch or take over
- Auto browse is US only and needs a Google AI Pro or Ultra subscription
- Daily action limits cap heavy use
Claude in Chrome
Claude in Chrome left beta on August 26, 2026 for paid Claude plans. Probes scan pages for injected instructions before Claude reads them, and a classifier checks each action against your request. Team and Enterprise owners can switch the extension off for the organization and set site allow-lists and block-lists, which also apply to the agent-owned browser in Claude Cowork.
Claude in Chrome
- Same admin console and site lists as the rest of Claude, including the Cowork browser
- Page probes and a safety classifier screen for injected instructions
- Optional agent-owned browser keeps the agent out of your logged-in sessions
- Desktop Chrome only
- Classifier-based approval trades human checkpoints for speed; set allow-lists before rollout

Frequently asked questions
Is Comet better than Chrome?
Comet is a standalone browser built around Perplexity's agent; Chrome now has its own agent, Gemini auto browse, for Google AI Pro and Ultra subscribers in the US. Comet is the better choice if you want an agent on every platform and enterprise controls that restrict actions by domain. Chrome with Gemini is the better choice if you do not want to roll out a new browser and prefer an agent that always hands purchases and posts back to you.
Can I use Claude in Chrome and Gemini in Chrome together?
Yes. Claude in Chrome is an extension and Gemini is built into Chrome, so both can be present in the same browser. For a company, that means two agents with access to the same sessions, so decide which one is approved and disable the other by policy.
Which agentic browser is safest?
None is safe by default with corporate logins in the same session. On published design, Gemini in Chrome keeps the most human checkpoints, Claude in Chrome adds page probes and a per-action safety classifier, and Comet Enterprise gives admins the most direct control over where actions are allowed. The safest setup is an agent with no access to your real sessions plus a domain allow-list.
How much does each cost?
As of October 2026: Comet is free, with Perplexity Pro at $20 a month, Max at $200 a month and Enterprise Pro at about $40 per seat a month. Gemini's auto browse needs Google AI Pro at $20 a month or AI Ultra at $100 a month. Claude in Chrome is included with paid Claude plans.
Final verdict
- Choose Comet if you want a dedicated agent browser on every device with the most direct admin control over where it can act.
- Choose Gemini in Chrome if you run Chrome, are in the US, and want the agent to hand every purchase and post back to a person.
- Choose Claude in Chrome if your team already uses Claude and you want the browser agent under the same admin console and site lists.
