Private Knowledge Base

Store, search, and summarize concepts across your PDFs and papers with fast semantic search and cross-document Q&A.

Personal document storage and retrieval system for PDFs, papers, and research documents.

Quick Start

Ingest Documents

# Add PDF to knowledge base
./scripts/ingest.sh ~/path/to/document.pdf

# Process entire folder
./scripts/ingest-folder.sh ~/papers/

Query Knowledge Base

# Search for concept across all documents
./scripts/search.sh "transformer architecture"

# Get summary of concept from relevant docs
./scripts/summarize.sh "attention mechanism"

Core Workflows

1. Document Ingestion

When user provides new PDFs or papers:

1. Create document entry in kb/index.json
2. Extract text and metadata
3. Generate embeddings for semantic search
4. Store in kb/docs/ with normalized name

2. Cross-Document Q&A

When user asks "which document mentions X?" or "summarize X from my docs":

1. Search embeddings for relevant passages
2. Retrieve source documents
3. Synthesize answer across documents
4. Cite sources with document names and page numbers

3. Concept Linking

Build associations between documents:

• Shared concepts
• Citation relationships
• Topic clusters

Usage Examples

User: "我之前存的文档里，哪篇提到了 transformer?" → Run ./scripts/search.sh "transformer"

User: "总结一下我文档里关于 attention 的内容" → Run ./scripts/summarize.sh "attention"

User: "把这篇 PDF 加到知识库" → Run ./scripts/ingest.sh <pdf-path>

Configuration

Set knowledge base location:

export KB_ROOT=~/.openclaw/workspace/kb

Default: ~/kb if not set.
