What is Claude
Claude is Anthropic’s general-purpose AI assistant for conversation, writing, analysis, and coding. It’s built for long context and “steerable, interpretable, and controllable” behavior.
Main features
- Long context: Handles ~200K tokens of input, so you can work with whole books, long reports, or large codebases.
- Writing and creation: Draft, polish, continue, or rewrite text with controlled style—good for reports, fiction, and scripts.
- Reasoning and structure: Strong at multi-step reasoning, comparison, summarization, and structured output.
- Coding help: Read code, write functions, refactor, and generate tests and docs.
- Safety and compliance: Training and product design emphasize lower bias, transparency, and control.
How to use
Use Claude at claude.ai or in integrated apps (e.g. some IDEs, Slack). Free and paid tiers are available; long-context and other features may depend on your plan.
