Best Polar Alternatives in 2026

Best for: People who already use Claude Code, Codex or Cursor and want their agent to work in a real, separate browser they can watch and replay

BrowserOS neo has no AI of its own: it is a browser built for an outside agent to drive. With Claude connected it completed all eight of our tasks and reported every result accurately, but that score belongs to the pair, and you need a paid AI agent and some setup to get there.

Best for: People who want accurate, sourced answers across their tabs and quick slide decks, and prefer an assistant that asks before it acts

Dia is the most careful AI browser we have tested: it asks before it reads or opens anything, got every research task right and built a real, sourced slide deck. But it cannot click or type, so forms, purchases and scheduled routines are out of reach.

Best for: Hands-on users who want a browser agent for research, form filling and data gathering and are comfortable reviewing what it installs

Strawberry got seven of our eight scripted tasks fully right, from quick web research to a sourced slide deck, but it installs two hidden Windows user accounts that stay behind after you uninstall it, uses about twice the memory of Edge and clicked “Add to basket” without asking. Capable agent, worrying footprint.

Best for: People who want a normal Chromium browser with a fast built-in answer panel, and do not need the AI to act on web pages for them

On the Free plan Comet is a fast, well-behaved Chromium browser with a quick answer panel, but not an agent: in eight scripted web tasks its Assistant never once clicked, typed or opened a tab, and every answer pointed us to Perplexity's separate Computer agent instead.

Best for: Tinkerers who want a free agent that clicks and types in the page, on a spare profile with no important logins

Genspark's free side-panel agent really does drive the browser: it researched, filled a form and compared prices well. But it got the harder half of our test wrong or not at all, misreported a form it had half-filled, and runs on a Chrome engine 15 versions old.
