Context for AI Agents

Nia gives better context to coding agents. It reduces hallucinations in LLMs by allowing agents to index any remote codebase, docs, or package. We also make sure they are always up to date.

4 sources indexed

This agent has all Nia open source codebases and docs indexed — just ask a question

Everything your agent needs, fully interactive through an API or MCP.

Nia provides the context layer that makes AI coding agents actually useful.

Watch Video

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 Video

Instant Package Search

Search pre-indexed packages like AI SDK for ground-truth code examples. Your agent never hallucinates.

Watch Video

Nia API

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

Watch Video

Oracle Research

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

Auto-Sync Sources

Never rely on outdated docs. We continuously monitor and update your indexed sources automatically.

Lowest hallucination rate

When LLMs encounter new APIs outside their training data, they guess. Nia provides ground truth, reducing hallucinations by 43%.

Where other tools fail

Enable Claude's extended thinking mode via the Python SDK

GPT-5 (No Context)
# ✗ "It is not possible to programmatically enable
# or extract Claude's hidden reasoning steps.
# There is no supported code-based method
# to override this."
With Nia Oracle
from anthropic import Anthropic, ThinkingConfigEnabled

client = Anthropic()

# ✓ Feature exists and works
response = client.messages.create(
    model='claude-4-5-sonnet-20250929',
    max_tokens=16000,
    thinking=ThinkingConfigEnabled(budget_tokens=2048),
    messages=[{'role': 'user', 'content': 'What is 25 * 47?'}]
)

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