What AI assistants are good at

AI assistants such as ChatGPT, Claude, Gemini and Microsoft Copilot can write, explain, summarize and organize information in seconds. Used well, they can save you hours every week.

These tools are built on large language models, which learn patterns from huge amounts of text and use them to predict useful responses. That makes them strong at language tasks, but it also means they can sound confident while being wrong.

The most useful mindset is to treat an AI assistant like a fast, capable helper whose work you always review. You stay in charge of the final result.
