Best for: People who want an AI browser that fills forms, opens tabs, builds files and runs scheduled tasks on its own, without paying for or setting up a separate agent
Polar's own agent did seven of our eight tasks and half of the eighth, quickly and with honest reports, on a free plan that barely noticed the cost. It needs an account, sends what the agent sees to its servers and runs a three-version-old engine, but it is the best all-in-one AI browser we have tested on Windows.
