Claude
Anthropic's AI assistant — available at Claude.ai and through the API. Claude is known for long context (it can read entire books or codebases), strong reasoning, careful honesty about what it knows and doesn't know, and being built with safety as a priority from the ground up. It's the focus of this knowledge hub. Different versions of Claude exist for different needs: lighter models for fast, simple tasks, and more powerful models for complex work.
In practice
You open Claude.ai, type "help me draft a rejection email that's kind but clear," and get a thoughtful draft in seconds. That's Claude — Anthropic's AI assistant. Under the hood it's a large language model trained to be genuinely helpful and honest. You can use it through the chat interface, through apps built on the API, or through Claude Code for software development.
