Hyperspell lets agents search, answer, and learn from internal knowledge. It works across uploaded documents, integrations like Notion, Gmail, and Slack, and raw text input. It provides fast semantic retrieval, optional question-answering, and user-specific permissions. Let your users connect to multiple sources and use Hyperspell’s end-to-end data pipeline to get structured data with a single API call.

​
