What is AI, in simple terms?

Artificial intelligence is software that learns patterns from examples instead of following only step-by-step rules written by a programmer. Show an AI system enough examples and it learns to recognize, sort, or create new things that fit the pattern.

How do ChatGPT and Claude work?

ChatGPT, made by OpenAI, and Claude, made by Anthropic, are large language models, or LLMs. They were trained on an enormous amount of text and learned to predict the next word, or more precisely the next token, in a sentence. When you ask a question, the model writes its answer one token at a time, each based on everything that came before. After that first training, the companies refine the models with human feedback and guidelines so they give helpful, honest, and safe answers.

Can AI be wrong?

Yes. Because a language model predicts likely words rather than looking facts up, it can produce answers that sound confident but are incorrect. This is sometimes called a hallucination. Always double-check facts, numbers, dates, and anything involving health, money, or legal decisions.

Is AI dangerous for seniors?

AI chatbots themselves can't access your bank accounts or listen to your home. The biggest real-world risk is scams, where criminals use AI to fake a family member's voice or create convincing fake messages. Set up a family code word, never send money based on an urgent call alone, and call back on a number you trust.

How can I get better answers from AI?

Be specific about what you want, give background about yourself and your goal, and ask follow-up questions to refine the result. Treat AI as a helpful assistant, and keep your own judgment in charge.
