# Infino: open-source retrieval engine for AI apps

> Infino is an open-source retrieval engine for full-text, vector, and SQL search, with your data stored as Apache Parquet on object storage.

You add Infino to your application as a library and query your data where it already
lives, on local disk or object storage like S3. Start with the quickstart, or see how
it works under the hood.
