What are the key differences between ChatGPT, Claude, Gemini, Copilot, and other top AI tools? Which one is best? How deeply should you be concerned about AI systems using your personal data? Are the reported inaccuracies and biases of the AI platforms really as bad as what I read?

Earlier this month, we asked you, WIRED subscribers, to send in your questions about generative artificial intelligence, and these are just some of the excellent queries we received. On Wednesday November 20, we hosted a live Q&A session with WIRED’s Reece Rogers, the author of the “AI Unlocked” newsletter, the monthly AI ethics and advice column “The Prompt,” and countless news and how-to articles about the impact AI is having on our lives.

If you missed the livestream, don’t worry—you can watch the whole thing right here. Reece was joined by WIRED global editorial director Katie Drummond, who made some opening remarks, as well as WIRED audience development manager Laura Fillbach, who served as moderator for the event.

In the 30 minute discussion, Rogers broke down the similarities and differences between the most popular generative AI tools, and shared which one he is willing to pay extra for. He covered the pros and cons of using AI-powered search instead of traditional search engines, and cautioned viewers against asking chatbots for specific medical advice. Rogers answered a few reader questions about the effectiveness of watermarks to signal if content was created using AI. He also drew on his personal experience to address questions about AI’s use in educational settings and the challenges teachers face in light of the fact that their students have such readily available access to AI tools.
