Ground your AI
in reality.

Vector search alone isn't enough. Hybrid search combines semantic understanding with keyword precision so your AI finds exactly what it needs, and doesn't hallucinate.

The Problem

Vector search alone fails your agents

Most AI platforms rely solely on vector embeddings for retrieval. That works for vague, conceptual queries. But when your agent needs to find invoice #INV-2024-3847, a specific error code, or a contract clause with exact dollar amounts, semantic similarity falls apart.

The result? Your agent confidently returns the wrong document, hallucinates details, or misses the answer entirely. That's why enterprise teams can't trust vector-only RAG in production.

Vector search only
"Find invoice INV-2024-3847"

Returns 5 invoices from 2024 that are "semantically similar." None of them are #3847. The agent picks one and presents wrong data with full confidence.

Hybrid search
"Find invoice INV-2024-3847"

Full-text search matches the exact invoice number. Vector search confirms semantic relevance. The agent gets the right document, every time.

How It Works

Two search strategies. One result.

Every query runs through both pipelines simultaneously. Results are scored, merged, and ranked so your agents always get the most relevant, accurate answer.

Semantic Vector Search

Understands meaning, not just keywords. "Q4 revenue projections" finds documents about "fourth quarter financial forecasts" even if those exact words don't appear.

  • Finds answers even when exact words don't match
  • Conceptual matching across languages
  • Best for exploratory and natural-language queries

Full-Text Keyword Search

Exact matching when precision matters. Invoice numbers, error codes, product SKUs, legal clause references. No approximation, no guessing.

  • Finds the exact document by ID, code, or reference
  • Stemming, ranking, and phrase matching built in
  • Best for structured data and specific lookups

Document Ingestion

Every format. Automatically parsed.

Drop files in and they're indexed. Intelligent parsing extracts clean text from any format while preserving structure, tables, and meaning.

PDF, DOCX, XLSX, PPTX, CSV, JSON, HTML, Markdown
Images with OCR for scanned documents
Automatic chunking and embedding generation
Incremental updates without full re-indexing
Intelligent Parsing

Tables, headers, lists, and metadata are all preserved. Scanned documents handled with OCR automatically.

Sub-millisecond queries

Millions of documents indexed and searchable instantly. Enterprise-scale performance without infrastructure headaches.

Incremental updates

Add or update documents without re-indexing everything. Your knowledge base stays current as your data changes.

Agent-ready

Search results feed directly into your UraiJS tools. Agents combine knowledge with live integrations for grounded answers.

Security

Your data stays under your control

Fine-grained access control ensures agents and users only see what they're authorized to see. Permissions are tied to your identity provider.

Document-level permissions

Control who can access which documents. Sales sees sales docs. Engineering sees engineering docs. Agents respect the same boundaries.

Team isolation

Multi-tenant by default. Each team or client has their own knowledge base, their own permissions, their own search index.

Audit trail

Every query, every document access is logged. Know exactly what your agents are reading and what they're using to generate answers.

Stop your agents from hallucinating.
