Claude Code

Claude is Anthropic's AI assistant and agent platform, built around Constitutional AI training intended to reduce hallucination and harmful outputs. The extended context window handles document-heavy work that breaks shorter-context alternatives — feeding an entire codebase or legal brief into a single session is the workflow it was designed for. The agent layer, including Claude Agents and Cowork, lets it plan and run multi-step tasks, execute code, search the web, and connect to external tools via MCP connectors. The ceiling appears when you need persistent memory outside a paid tier or need to self-host for compliance — neither is available. Teams with strict data residency requirements reach that wall quickly.
