index anything.
search it with ai.

The index and search layer for AI agents. Point Nia at any source — code, docs, PDFs, datasets, the web — and give every agent one API to retrieve, traverse, and cite. Scalable, 5x cheaper, reliable.

Nia [by Nozomio Labs] is still the best tool I've tried, and I'm willing to pay more because it's been working so well with Claude Code

Features

Everything your agent needs to retrieve, traverse, and cite — through an API, CLI, Skill, or MCP, across every source.

Watch

Nia API

Build custom agents and workflows tailored for your company using Nia's API.

Watch

Tracer

An autonomous GitHub search subagent. No pre-indexing required—give it a question and repos to search. Powered by Claude Opus 4.6 with 1M context window.

Watch

Universal Search

Sub-5s responses across millions of indexed pages and GitHub files. Tiny AI models compress results in milliseconds for token-efficient answers.

Watch

Oracle Research

SOTA search designed to reduce hallucinations. Turns indexed codebases into a dynamic tree your agent queries on the fly.

Watch

Context Sharing

Save conversation histories, plans, and referenced sources. Resume in another agent without losing the thread.

Watch

HuggingFace Datasets

Index any HuggingFace dataset—visualize, search, and reason over it. From anime quotes to scientific papers.

Watch

Autosubscribe

Feed your package.json or requirements.txt to Nia. We parse dependencies, resolve docs URLs, and index everything within minutes—instant context on every library.

Watch

Sync Engine

Continuously sync local folders, databases, and chat history. Your personal knowledge base—iMessage, browser history, notes—searchable by your agents.

Watch

Scoped MCP Servers

Spin up specialized MCP servers for specific sources. One framework, one docs site—fewer tools, less noise, focused context for your agent.

Watch

Document Agent

An agent that reasons over any document—papers, books, engineering drawings. Browses the table of contents, reads sections, keeps searching until it finds a real answer. Every claim cites a page number.

Benchmark

Retrieval is the hardest part of agent reliability. We tested ourselves on the worst case — bleeding-edge APIs LLMs have never seen — and beat every alternative. Same engine works on any source.

# There is no supported code-based method

With Nia Oracle
from anthropic import Anthropic, ThinkingConfigEnabled

client = Anthropic()

# ✓ Feature exists and works
response = client.messages.create(
    model='claude-4-5-sonnet-20250929',

    thinking=ThinkingConfigEnabled(budget_tokens=2048),

)

For AI agents to be truly autonomous, they need reliable access to ground truth.
