Personal AI Knowledge Base
A privacy-first, self-hosted knowledge management system that ingests documents, web pages, and notes into a searchable vector database with local LLM-powered chat and RAG capabilities.
Document Intelligence
Handles ingestion and parsing of 15+ file formats including complex PDFs, Office documents, and images into clean, structured markdown
Essential for personal KBs because it parses 15+ formats (PDF, DOCX, PPTX, XLSX, images, audio) with layout preservation and reading order detection—critical for understanding tables and multi-column documents that generic loaders mishandle.
Lightweight Python alternative for quick Office document-to-Markdown conversion when Docling's advanced features aren't needed; preserves headings and tables effectively.
Web Ingestion
Converts web pages and articles into LLM-ready markdown with citations for online research integration
Vector Memory
Stores document embeddings for semantic search and retrieval-augmented generation
Selected for its dead-simple 4-function API (add/query/update/delete) and zero-config SQLite backend—ideal for personal deployments where you want vector search without managing a separate database server.
High-performance alternative if your knowledge base scales beyond 50k documents or requires hybrid search (sparse vectors) for better keyword matching on technical terms.
LLM Inference
Privacy-preserving local language model serving with no data leaving your device
Interface & RAG
Unified chat interface with built-in retrieval-augmented generation and multi-model support
Self-hosted ChatGPT alternative that connects to Ollama and supports RAG out-of-the-box with 9 vector databases (including Chroma)—features document uploading, web search integration, and conversation history with full data control.
Switch to RAGFlow if you need deep document understanding with traceable citations and grounded references to reduce hallucinations on complex technical documents—though it requires more setup than Open WebUI.
Workflow Automation
Automates document ingestion pipelines and knowledge base maintenance
