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