What is Agentset?
Agentset is infrastructure for developers building RAG (retrieval-augmented generation) applications, powering search and Q&A inside their products. You upload your documents through JavaScript or Python SDKs, or via connectors to sources like Google Drive, SharePoint and Notion. Agentset handles extraction, chunking, hybrid search with reranking and agentic reasoning, then returns answers with automatic citations to the sources.
In practice you can use it to add a chat interface over a large document set, filter answers by metadata, work with images, graphs and tables alongside text, and expose the knowledge base to external apps through an MCP server or the AI SDK. The vector database, embedding model and LLM are selectable, so the stack can be adapted to existing infrastructure.
