Claude
- +Strong writing, reasoning, and coding plus interactive Artifacts in one assistant
- +Open MCP Connectors wire it into Gmail, Workspace, Slack, Jira, and Zapier
- +Generous free tier across web, desktop, and mobile; Research and Cowork add real agentic work
- -Most of the product is assistant/copilot grade; the agentic modes are newer and narrower
- -Cowork ships as a research preview and (for now) on the desktop app
LlamaIndex
- +Best-in-class data and retrieval primitives (readers, indexes, retrievers, query engines) for grounding agents in your own data
- +Event-driven Workflows orchestrate multi-step agent processes with reflection and error-correction
- +Open source and model-agnostic, with LlamaCloud for managed document parsing and indexing
- -Framework, not a product: autonomy and quality depend entirely on what the developer builds
- -More oriented to data/RAG than to complex multi-agent orchestration compared with some peers
