Best AI browsers

There are two products wearing this label: browsers built around an assistant, and ordinary browsers with an assistant bolted into a sidebar. This guide selects the first kind, and says plainly where the second kind is the better choice.

Criteria used before recommendations

We establish rigorous boundary rules before selecting browsers. Every recommendation must satisfy these requirements:

  • The assistant is the product's organising idea, not a panel beside the tabs
  • Whether it only answers, or also navigates, clicks, and fills forms for you
  • Documented controls over retention, training, and local processing
  • A browser still worth using on the day you ignore the AI entirely

    Reviewed 2026-09-16

    Comet
    chromiumactivePerplexity AI
    View profile

    Choose Comet when you want an answer engine and an acting assistant as the primary way you browse, and you are comfortable being an early adopter.

    Status
    Actively developed, with desktop and mobile releases and rapidly changing capabilities.
    Caveat
    Avoid it for sensitive accounts or work, where an assistant with access to logged-in tabs is a larger attack surface than a conventional browser.

    Reviewed 2026-09-16

    Opera Neon
    chromiumactiveOpera
    View profile

    Consider Opera Neon only if delegating multi-step web work is a real part of your day and you will use it enough to justify a monthly subscription.

    Status
    Released with a free browsing plan since August 2026; the built-in agents require a paid subscription.
    Caveat
    Avoid it as a general-purpose browser: it is desktop-only, its agents are paid, and it is built around a workflow most people do not have.

    Choose Dia only to evaluate an early AI-centered browsing workflow and provide feedback, not as a stable default for critical work.

    Status
    Generally available for macOS with frequent releases and paid plans; Windows support is in progress.
    Caveat
    Avoid it when predictable privacy boundaries, broad platform support, mature extensions, or long-term compatibility are required.

    Strawberry logo
    Strawberry
    chromiumexperimentalStrawberry

    Try Strawberry only as an experiment, on non-sensitive accounts, if delegated multi-step web work is something you actively want to test.

    Status
    In open beta with a credit-based commercial model and rapidly changing capabilities.
    Caveat
    Avoid it for anything consequential: it is a beta whose assistants act inside sessions where you are already signed in.

Editorial view

The distinction that decides this choice is between assistants that answer and assistants that act. Summarising a page, drafting a reply, or explaining a document carries roughly the risk of a browser extension. An agent that navigates, clicks, and fills forms is operating inside sessions where you are already signed in, with your privileges, and instructions hidden in page content being read as your commands is a live, publicly documented attack class across this entire category.

The acting kind

  • Comet is the most complete and the first selection: Perplexity's answer engine is the default search path, the assistant works across open tabs, and it ships on desktop and both mobile platforms, which none of the others manage.
  • Opera Neon is the most explicit about delegation: the browser now has a free plan, but its built-in agents that hand over multi-step work sit behind the subscription.
  • Dia is the current product from Arc's makers, supervised rather than autonomous, and still macOS-first.
  • Strawberry is the narrowest and most interesting: persistent companions that work across your logged-in tabs and pause for approval on consequential steps, in a beta with a credit-based price.

Now the honest part

For most people reading this, one of the alternatives is the better browser. Edge's Copilot is the strongest answering assistant and the only one with real enterprise data controls. Brave's Leo is the one to pick if you want the assistant without surrendering privacy posture: documented no retention or training on conversations, model choice, and local models. Neither is an AI browser in the sense this page uses, and that is a point in their favour if you are unsure.

Two things to do regardless

Read the AI privacy fields on each profile rather than the marketing, because several vendors leave retention and training undocumented. And keep genuinely consequential accounts, banking, health, your primary email, in a browser whose assistant cannot act on them.

Secondary Options

Alternatives

Why other browsers are not primary selections

Edge and Brave are excluded from the selections and listed as alternatives instead, and Chrome and Opera stay off the list for the same reason. Each has a capable assistant, and for most readers one of them is the sensible choice - but they are conventional browsers with a panel attached, and putting them on a list of AI browsers hides the distinction that actually matters. Vivaldi is excluded because it documents a deliberate decision not to ship these features, which is a position rather than an omission. Opera Air is not a substitute for Opera Neon: it is a minimal Opera variant with the same optional assistant panel, not an agent.
