What Is Claude? — The Big Picture
"I keep hearing about AI, but where do I start?" "I've heard of ChatGPT — how is Claude different?"
This page is for you. By the end, you'll understand the big picture of Claude and know exactly what to try first.
Claude Is an AI Assistant Built for Safety
Claude is an AI assistant developed by Anthropic. It handles a wide range of tasks: writing documents, answering questions, analyzing data, helping with code, and much more.
Like ChatGPT (by OpenAI) and Gemini (by Google), Claude is built on "large language model" (LLM) technology. But Claude stands out in several ways:
- Safety-first design — Anthropic was founded to develop AI safely. Claude is carefully designed to avoid harmful responses
- Excellent with long documents — Claude can process up to 1 million tokens (roughly 750,000 English words — about 10 full novels) in a single conversation
- An agent that gets things done — Beyond just answering questions, Claude can edit files, run code, and take real action as an "agent"
New to AI? Don't worry about terms like "LLM" or "tokens." The key takeaway is: Claude is a smart AI assistant that can help with many different tasks.
