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.
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.
Universal Search
Sub-5s responses across millions of indexed pages and GitHub files. Tiny AI models compress results in milliseconds for token-efficient answers.
Instant Package Search
Search pre-indexed packages like AI SDK for ground-truth code examples. Your agent never hallucinates.
Nia API
Build custom agents and workflows tailored for your company using Nia's API.
Oracle Research
SOTA search designed to reduce hallucinations. Turns indexed codebases into a dynamic tree your agent queries on the fly.
Context Sharing
Save conversation histories, plans, and referenced sources. Resume in another agent without losing the thread.
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Never rely on outdated docs.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%.

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