Context7
Up-to-date code documentation for LLMs and AI code editors.
LLMs rely on outdated or generic information about the libraries you use. You get:
- ❌ Code examples are outdated and based on year-old training data - ❌ Hallucinated APIs that don't even exist - ❌ Generic answers for old package versions
Context7 pulls up-to-date, version-specific documentation and code examples straight from the source — and places them directly into your prompt.

Feeding up to date library documentation to a model is exactly the grounding these tools need, and it measurably cut the hallucinated API calls in my sessions. Coverage on the popular libraries is strong. I would love a way to pin a specific version per project.
Right doc, right version, in the prompt. It removed a whole class of wrong answers from my day. Setup was two minutes and I have not thought about it since. The model stopped inventing methods that do not exist, which is the entire job and it does it.
Pulling current docs straight into the editor instead of guessing at a stale version has quietly fixed a daily annoyance. The lookups are quick and the snippets land in context. It is the kind of utility you forget you installed because it just works.
