Comparison list
The best AI browsers for iPhone, sorted by what the agent actually does.
Almost every browser claims AI on the iPhone. Few ship an agent that reads and clicks. This list keeps the ones that do, plus one worth watching, and says where each one runs the work and what it costs.
How this list was built
The iPhone forces every browser onto WebKit, so an engine comparison says nothing here. What separates these apps is the agent: whether it exists on iOS at all, whether it clicks in the app or in a machine somewhere else, and whether it asks before it does something you cannot undo.
Every fact below was read on the App Store listing or on the vendor's own site on 30 October 2026, and the sources are listed at the end of the page. Where a vendor does not state something, the row says so instead of guessing. Prices are US list prices on that date.
This is a list of browsers with an agent, not a ranking. Peji is ours, and the entry for it says what it does not do as plainly as the others.
Peji
Peji opens real WebKit tabs on the iPhone and drives them: it navigates, reads, looks at the page, clicks, types, presses, scrolls and can run a script. Every action is listed in the chat while it happens, and a run stops before anything that sends, buys, books, pays, publishes or deletes.
Chats, tabs and files stay on the iPhone as local files. The browser and the dictation are local; the model is remote. The built-in provider comes with the app, and any OpenAI-compatible endpoint can replace it, with the key in the Keychain.
It is the pick if you want the agent to work on the phone, on sites where you are already signed in, and to stop before the click that costs something. It is not the pick for research reports, for a desktop browser, or for cross-device sync: there is none of the three.
- Free on the App Store, iOS 18.6 or later. Pro adds monthly usage for the built-in provider, $8.99 a month or $89.99 a year.
- Every feature is in the free plan: routines, custom instructions, iCloud backup, your own endpoint.
- The model is remote. Peji is not an offline agent.
Comet, by Perplexity
Comet has been on the App Store since March 2026 and is the most complete AI browser on the iPhone today. The assistant answers about the page you are on, compares tabs, cites sources and runs Deep Research. The free tier exists; Pro and Max are the paid ones.
The agent is the part to read carefully. On the iPhone Comet does not click inside the app: it opens a virtual browser in Perplexity's cloud, transfers the cookies it needs to act as you, and deletes them when the task ends. MacStories described the mechanism in March 2026 and Comet's own prompt said the same to us in October 2026. That makes it the strongest option for a long research task and the one to think twice about on a bank or a mailbox.
It is the pick if you already pay for Perplexity, want research and sync across machines, and are comfortable with the work happening off the phone.
- Free to download. Perplexity Pro $20 a month, Max $200 a month, read on 30 October 2026.
- Also on macOS, Windows and Android, with the same account.
- The App Store privacy label declares browsing history, usage data, diagnostics, contact information and approximate location, not linked to your identity.
Sigma
Sigma is the most interesting case in this list because the iPhone app and the desktop app are not the same product. On macOS and Windows Sigma ships an AI Agent that navigates pages, fills forms and clicks, with OpenClaw or Hermes and an option to run local models in Private Mode.
On the iPhone, Sigma's own page describes AI chat, chat with a page, a built-in ad blocker, private browsing and sync of AI chats. The agent is not described for iOS, and the App Store listing does not mention one. So on the phone this is an AI browser with a good assistant, not an agentic one.
It is the pick if you want the same chat across your Mac and your iPhone and you like the privacy framing, and the agent on the desktop is the reason to look at it.
- Free to download, 3.9 stars from 10 ratings on the US App Store on 30 October 2026.
- Plus $10 a month, Pro $75 a month, from Sigma's own price page.
- The agent and local models are features of the desktop app.
Arc Search
Arc Search brought Browse for Me to the iPhone in 2024: one tap, and the browser reads a handful of pages and builds an answer page. It is fast, ad-free and pleasant, and the pinch-to-summarize gesture still has no equal.
It is also the app this whole category grew out of, and the one with the least certain future. The Browser Company moved to Atlassian in 2025, and Arc is no longer the product the company is building. Browse for Me compiles and reports; it does not fill a form or complete a checkout.
It is the pick for reading and answering quickly on a phone you do not want to think about, with the caveat that the roadmap is not the one it was two years ago.
- Free, no subscription on the iPhone.
- Browse for Me and pinch to summarize. No action across sites.
- Reputation: 4.9 stars from about 25,000 ratings on the US App Store, 30 October 2026.
Genspark
Genspark is an agent workspace rather than a browser: the Super Agent researches, builds slides and sheets, and works in the cloud while the app is closed. It is capable and it is not a place to browse.
It is the pick if you want an agent that produces a deliverable and you keep Safari or another browser for the web itself.
- Free to download, paid tiers in-app.
- The work happens in Genspark's cloud, not in tabs on the phone.
Also considered, and left out
Safari has Apple Intelligence and no agent that clicks across sites, and it is the browser everyone already has. Brave on iOS has Leo for answers, not for actions; its own list of agentic features lives on the desktop. Chrome and Edge on iOS are WebKit shells with a chat panel. ChatGPT Atlas has no iPhone app.
The test for this list is narrow on purpose: an agent that acts on the iPhone, or a chat that gets close enough to be a real alternative. A browser that summarizes a page is a reading tool, and the list of those would be much longer and much less useful.

Questions
What is the best AI browser for iPhone?
There is no single answer, because the two best ones do different things. Comet is the strongest for research and for syncing with a desktop browser, with the agent running in a cloud machine. Peji is the strongest for acting on the phone, in tabs where you are already signed in, with a confirmation before anything that sends or pays. Sigma and Arc Search are assistant browsers rather than agents on iOS.
Which AI browsers have an agent that works on the iPhone?
Two that we could confirm on 30 October 2026: Peji, which drives WebKit tabs on the phone, and Comet, which drives a virtual browser in Perplexity's cloud. Sigma's agent and Genspark's Super Agent work off the phone, on desktop or in the cloud. Arc Search reads and summarizes but does not act.
Are AI browsers on iPhone free?
All five in this list are free to download. Comet charges through Perplexity Pro at $20 a month, Sigma through Plus at $10 and Pro at $75, and Peji Pro at $8.99 a month or $89.99 a year for more usage of the built-in provider. Arc Search is free.
Do AI browsers on iPhone use different engines?
No. iOS requires WebKit for every browser, so Comet, Sigma, Arc Search and Peji all run on the same engine as Safari. The difference between them is the assistant and the agent, never the rendering engine.
