Ranks are from our full ranking of general AI assistants (6 tools). ChatGPT, our #1, also lists a free plan in our fact sheet, but OpenAI's pricing page did not load for us on Nov 10, 2026, so it is not listed here. Gemini's free access is not on our sourced fact sheet yet. Ranked tools not listed have no ongoing free plan on their pricing page or our fact sheet. Free plans change often, so check the official page before you rely on one. Nothing on this page is sponsored.
