Nia - Index Anything. Search It with AI.

Index docs, repos, PDFs, and datasets -- then search them with AI. Backed by Y Combinator ($6.2M raised)

Nia lets you index docs, repos, PDFs, datasets, spreadsheets, Slack, Google Drive, and more -- then gives your AI agent a search API to query them. Your agent gets real answers instead of hallucinations.

What is Nia?

Nia is an API layer that gives agents up-to-date, continuously monitored context across repositories, documentation, PDFs, datasets, Slack, Google Drive, and local knowledge sources. It handles indexing, search, reading, research, and handoffs so agents can work from real source material instead of guesswork.

You can use it with agents like Cursor or Claude Code as an MCP server, or build your own applications with the Nia API.

Core Capabilities:

• Universal Indexing - Index GitHub repos, documentation sites, PDFs, arXiv papers, HuggingFace datasets, spreadsheets, and local folders
• Universal Search - Sub-5s semantic search across all indexed sources
• Package Search - Search 150M+ pre-indexed documents from PyPI, NPM, Crates.io, and Go modules -- no indexing required
• Document Agent - Deploy an autonomous AI agent into any indexed PDF or document for deep research with cited answers
• Data Extraction - Extract structured data from PDFs into JSON using custom schemas
• Tracer - Search GitHub code without indexing using specialized sub-agents (Fast mode with Haiku, Deep mode with Opus)
• Oracle Research Agent - Autonomous deep research across codebases and documentation
• Context Sharing - Save plans, discoveries, and conversation state between different agents
• Connectors - Integrate Notion, Confluence, and other external sources via OAuth/API key
• Google Drive Integration - Browse, select, index, and keep Drive content synced
• Slack Search - Index Slack workspaces and search conversations semantically
• E2E Encryption - Zero-knowledge sync for iMessage, WhatsApp, Apple Notes, Contacts, and more
• Local Sync - Sync local folders, databases, and chat history with continuous monitoring
• Scoped MCP - Create task-specific MCP surfaces for focused workflows
• Auto-Sync - Sources are continuously monitored and updated automatically
• API & MCP - Available as an API or MCP server for any agent

Example: Using Nia in Cursor with Package and Documentation Search

Documentation Sites	index on any URL	llms.txt aware, supports crawl filters
PDFs & Research Papers	index on PDF/arXiv URL	Section-aware retrieval, Document Agent
HuggingFace Datasets	index on dataset URL	Row-level search, schema discovery
Google Drive	OAuth integration	Docs, Sheets, Slides, PDFs with incremental sync
Spreadsheets	index CSV/TSV/XLSX/XLS	Row-aware, header-aware indexing
Slack	Workspace integration	Real-time sync via Events API
X (Twitter)	Account indexing	Semantic search over posts and threads
Local Folders	index(folder_path=...)	Continuous sync available
Connectors	Notion, Confluence, etc.	OAuth and API key auth with scheduled sync
E2E Encrypted	TypeScript SDK	iMessage, WhatsApp, Notes, Contacts, Reminders

Key Features

Document Agent

Deploy an autonomous AI agent into any indexed PDF or document. It plans its own research strategy, navigates document structure, and produces answers with section-aware citations. Supports structured JSON output and streaming.

Data Extraction

Extract structured records from PDFs -- financial filings, invoices, spec sheets, engineering drawings. Three modes: table extraction, visual element detection, and engineering extraction.

Tracer

Search GitHub code without indexing. Tracer delegates tasks to specialized sub-agents operating in parallel. Fast mode (Haiku) for quick lookups, Deep mode (Opus 1M context) for thorough investigations.

Package Search (No Indexing Required)

Search 150M+ pre-indexed documents from PyPI, NPM, Crates.io, and Go modules. Regex and semantic search across public package source code.

Oracle Research Agent

Autonomous deep research across codebases and documentation. Chains multiple searches and builds dynamic knowledge trees for complex questions.

Context Sharing

Save plans, discoveries, edited files, and conversation state so another agent can pick up where you left off. Supports scratchpad, episodic, fact, and procedural memory types.

Connectors

Integrate external data sources through a unified framework. Supports Notion, Confluence, and more with OAuth/API key authentication, scheduled syncing, and status monitoring.

E2E Encryption

Zero-knowledge sync for personal data -- iMessage, WhatsApp, Apple Notes, Contacts, Reminders, Stickies, and Screenshots. Plaintext never leaves your device.

Use Cases

Developers are building diverse applications with Nia's API:

• Community forum search (Cursor Forum Search -- 5,000+ pages indexed)
• Knowledge base Q&A (Paul Graham Essays, Naval Wisdom)
• Document archives (Epstein Archive, legal research)
• Blog search (Simon Willison's Weblog -- 4,500+ posts)
• Dataset exploration (HuggingFace datasets)
• Code review agents that fetch up-to-date documentation on demand
• Law research agents indexing legal PDFs
• PDF book agents for students and researchers
• Custom search engines for any content
