The chatbot that started the boom remains the default for good reason: strong writing, coding help, brainstorming, and broad general knowledge. The free tier handles most daily tasks comfortably. If you only try one AI chatbot, make it this one. Its voice mode and image understanding make it feel closer to a real assistant than a text box.
Best for: all-round everyday AI assistance.

Google's assistant is fast, capable, and deeply wired into Search, Gmail, and Docs. The free tier is generous — no paywall stands between you and the core experience. The obvious pick if you already live in Google's ecosystem. It can pull from your emails and files to give personalized answers.
Best for: Google users who want a free, fast assistant.
