Cratemate offers a RAG (retrieval augmented generation) search over all crates.io crates. This means it has embeddings for all crates and your search term will then be expanded with a LLM to provide the best crate for a particular problem. You can just phrase what you want to do with Rust and Cratemate will provide a response how to achieve this with.

Cratemate crates.io is currently only updated every couple of days. Hence the newest crates will not always be visible here.
