nia

Overview

Nia is a context-augmentation layer for AI agents, primarily designed for coding assistants. It provides up-to-date knowledge base capabilities by indexing and searching across GitHub repositories, documentation, PDFs, datasets, spreadsheets, Slack, Google Drive, and more. The service improves agent performance by 27% according to the developers. Nia can be used as both an API and an MCP server, offering features like semantic search, package search without indexing, document agents for deep research, and context sharing between agents.
