# Capabilities

> What the Isaacus API can do for you

The Isaacus API supports a wide range of information retrieval, extraction, and classification tasks, including:

* [Enrichment](/capabilities/enrichment): transforming unstructured documents into rich, structured, hierarchical knowledge graphs representing key sections, concepts, entities, and their relationships to one another.
* [Embedding](/capabilities/embedding): transforming queries and documents into highly compressed, high fidelity numerical representations to power semantic search, text classification, and clustering.
* [Reranking](/capabilities/reranking): scoring and sorting documents based on their relevance to search queries.
* [Extractive question answering](/capabilities/extractive-question-answering): extracting answers to questions from documents with high precision and throughput.
* [Universal classification](/capabilities/universal-classification): classifying and extracting clauses from documents based on your own criteria, with no prior examples necessary.
