Build an Enterprise Private Knowledge Base with Claude + Vector Database: Answer Any Employee Question Instantly
Enterprise documents are scattered across Confluence, Feishu, and local folders, making it slow for new hires to get up to speed and for experienced employees to find documents. This solution introduces how to build a private knowledge base Q&A system using Claude API + Chroma vector database + simple Python scripts, deployable within 4 hours without the need for professional engineers.

Organize enterprise documents: Export PDF/Markdown files from Confluence/Feishu
- 2
Install dependencies: pip install chromadb langchain anthropic
- 3
Write document loading script: Read files, split into chunks of 500-1000 characters, generate vectors, and store in Chroma

- 5
Add citation sources: Require Claude to annotate at the end of the answer with 'Source: [document name]'
