"Khoj is an open source AI second brain solution that supports local or cloud deployment. It can connect to any large language model (such as GPT, Claude, Llama, etc.), realize document intelligent question answering, automated research, cross-platform access and other functions, and can be called an all-round AI assistant for individuals and enterprises!"

Why do you need this AI brain?

In the era of information explosion, we face:

  • Massive documents are difficult to retrieve quickly (papers/reports/e-books)
  • Repeated research consumes a lot of time
  • Multi-platform data cannot be managed uniformly
  • Sensitive data needs to be privately deployed

Khoj solves these pain points through three major innovations:

  1. Full stack intelligence : document understanding + network research + automated processes
  2. Model freedom : support free switching of 30+ mainstream large models
  3. Privacy-free : Supports fully offline deployment

Six core functions

1. All-round document manager

# Document processing example
from  khoj.processor  import  FileProcessor

processor = FileProcessor()
# Support PDF/Markdown/Word/Notion and other formats
processed_data = processor.ingest( "Annual Report.pdf"
# Generate an intelligent knowledge base with semantic indexing
  • Supported formats: PDF/Image/Markdown/Word/Notion
  • Core Competencies:
    • Cross-document semantic search (Chinese and English mixed retrieval)
    • Automatically generate knowledge graph
    • Version History

2. Intelligent Research Assistant

# Start the automated research task
curl -X POST https://api.khoj.dev/research \
  -H  "Content-Type: application/json"  \
  -d  '{
    "topic": "Development trend of AI chips in 2024",
    "sources": ["arxiv", "Industry White Paper"],
    "schedule": "daily"
  }'

  • Features:
    • Automatically generate industry daily reports
    • Dynamic monitoring of competitors
    • Paper Trend Analysis

3. Full platform access matrix

  • Support channels:
    • Browser plugins
    • Obsidian/Emacs plugin
    • Desktop Client
    • WhatsApp bot
    • REST API
