Claude, explained simply
Claude is an AI assistant built by Anthropic. You can chat with it on the web or in an app, and developers can use it through an API.
It matters because it is one of the main AI choices alongside ChatGPT and Gemini. It helps with writing, reading long documents and coding.
For example, you can paste in a long report and ask for a short summary. It replies in a few lines.
Like all chatbots, it can be wrong. Check important facts.
