Context7 solves the stale-docs problem: instead of relying on an LLM's outdated training data, it fetches live, version-specific documentation for thousands of popular libraries and injects it directly into the model's context window. Ask Claude Code to use React 19, Next.js 15, or any other library and get answers grounded in the actual current API — not hallucinated method signatures from two years ago.
