RAG infrastructure you own
Find the needle in your
private haystack
Hybrid search, grounded agent responses, and large-scale document management. Full data ownership: cloud, air-gapped, or on-premise.
01 · Capabilities
Document management
Large-scale ingestion of any document type.
- Contextual chunking to preserve context
- Document deduplication
- Parse text, images, tables
Search
Choose between a fast embedding search and a high-precision reranked retrieval.
- LLM reranking
- Flexible search depth
- Keyword-assisted search
Grounded agents
Every AI response is grounded in your documents. The agent retrieves context via tool calls and cites every claim back to its source.
- Inline source citations
- Shared document-base between sessions
- Real-time agent actions monitoring
02 · Pipeline
Upload
Drop your PDFs into the ingestion interface.
Process
Documents are parsed, chunked with surrounding context preserved, and embedded.
Index
Chunks are stored in PostgreSQL with HNSW vector indexes and language-aware full-text search indexes.
Retrieve
Perform manual searches to maintain full control, or use the chat interface.
