Combines vector similarity search with BM25 keyword matching to retrieve relevant document chunks, using late chunking and AI-powered reranking to surface the most contextually relevant results. The system maintains parallel vector and keyword indices, executes both search paths concurrently, and applies a learned reranker to fuse results before passing to the LLM, enabling both semantic and lexical relevance.
Unique: Implements late chunking with AI-powered reranking rather than simple vector similarity, allowing the system to balance semantic relevance against keyword precision and reduce context noise before LLM inference. The dual-index approach with concurrent execution avoids the latency penalty of sequential search.
vs alternatives: More precise than pure vector search (reduces hallucinations from irrelevant semantic matches) and faster than sequential BM25+reranking because both indices are queried in parallel with fused results.
Processes documents in multiple formats (PDF, DOCX, TXT, Markdown) through a unified pipeline that extracts text, applies contextual enrichment to preserve document structure and relationships, and batches processing for efficiency. The system uses format-specific parsers, maintains document metadata, and enriches chunks with surrounding context before vectorization to improve retrieval quality.
Unique: Applies contextual enrichment during ingestion (preserving document structure and surrounding context) rather than treating chunks as isolated units, improving downstream retrieval quality. The batch processing pipeline allows efficient handling of large document collections without memory exhaustion.
vs alternatives: Preserves document hierarchy and context during chunking (unlike simple text splitting), reducing context loss and improving retrieval relevance compared to naive document processing approaches.
Ensures all data processing (documents, embeddings, chat history, model inference) occurs locally without external API calls or data transmission, using local storage (LanceDB for vectors, SQLite for chat history) and Ollama for model inference. The system is designed for air-gapped or restricted-network environments where data cannot leave the organization.
Unique: Implements complete data isolation by design, with all components (models, storage, inference) running locally and no external API dependencies. This is a fundamental architectural choice rather than an optional feature.
vs alternatives: Provides absolute data privacy compared to cloud-based RAG systems, eliminating data transmission risks and enabling compliance with strict data residency requirements.
Implements a multi-service architecture where document processing, retrieval, generation, and API layers are independently deployable and configurable services orchestrated by a central run_system.py script. Each service has well-defined responsibilities and APIs, allowing developers to swap components (e.g., different embedding models, retrieval strategies) without modifying other services.
Unique: Separates concerns into independently deployable services (document processing, retrieval, generation, API) with well-defined interfaces, allowing component swapping and independent scaling. The orchestrator manages service lifecycle and health.
vs alternatives: More flexible than monolithic systems for customization, while service isolation enables independent optimization and scaling of bottleneck components.
Manages local LLM and embedding model inference through Ollama, allowing users to run multiple model types (chat, embedding, reranking) on local hardware without external API calls. The system communicates with Ollama via HTTP endpoints (localhost:11434), handles model lifecycle management, and supports dynamic model switching based on query complexity through smart routing.
Unique: Implements smart routing between RAG and direct LLM paths based on query complexity, dynamically selecting which model to use rather than always using the same inference path. This allows cost and latency optimization without manual intervention.
vs alternatives: Eliminates cloud API dependencies and data transmission compared to cloud-based LLM services, while supporting dynamic model switching for cost/quality tradeoffs that single-model systems cannot provide.
Maintains conversation state across multiple turns using SQLite-backed session management, enabling context-aware follow-up questions and multi-turn reasoning. The system streams responses in real-time to the web interface, tracks session metadata, and allows users to manage multiple independent conversation threads without context bleed.
Unique: Combines session-based context management with real-time streaming responses, allowing users to see results as they're generated while maintaining full conversation history. The SQLite backend provides simple local persistence without external dependencies.
vs alternatives: Enables true multi-turn reasoning with context awareness (unlike stateless single-turn systems), while streaming responses provides better UX than batch response generation.
Breaks complex multi-part questions into sub-queries, executes each independently through the RAG pipeline, and verifies answers against source documents before returning to the user. The system uses the LLM to decompose queries, routes each sub-query through retrieval and generation, and applies verification logic to detect hallucinations or unsupported claims.
Unique: Implements answer verification as a post-generation step that checks claims against source documents, rather than relying solely on retrieval quality. This two-stage approach (generate + verify) catches hallucinations that pure retrieval-based systems miss.
vs alternatives: Reduces hallucinations compared to single-pass RAG by verifying answers against sources, while query decomposition enables reasoning over complex multi-part questions that simple retrieval cannot handle.
Caches embeddings and retrieval results for semantically similar queries, avoiding redundant vector search and LLM inference when users ask variations of the same question. The system compares incoming query embeddings against cached queries using similarity thresholds, returns cached results when similarity exceeds the threshold, and updates the cache with new queries.
Unique: Uses semantic similarity (embedding-based) rather than exact string matching for cache lookups, allowing cache hits on paraphrased or slightly different versions of the same question. This is more effective than keyword-based caching for natural language queries.
vs alternatives: More effective than simple string-based caching because it catches semantically equivalent questions, reducing redundant inference while maintaining result freshness through configurable similarity thresholds.
