Khoj

open sourceexplicit relation

Khoj is an open-source personal AI app that serves as a self-hostable second brain. It connects to your documents — PDFs, Markdown, Notion, Word — and uses RAG to answer questions grounded in your knowledge base. Supports any local or cloud LLM including Llama, Claude, GPT, and Gemini. Features custom agents, scheduled automations, deep research mode, semantic search, and Obsidian, Emacs, and WhatsApp integrations. Over 33,000 GitHub stars, YC-backed.

Free and 100% open source under the AGPL-3.0 license. Khoj has zero software licensing fees and is designed for self-hosting on local hardware or private servers. Operating costs are $0 when running with local LLMs (via Ollama) and local embeddings, or strictly pay-as-you-go for token consumption if using external BYOK LLM API keys (OpenAI, Anthropic, Gemini).
