Khoj

What is Khoj?

The docs describe Khoj as an "AI second brain" — a self-hostable tool that answers questions from your personal documents or the web. The repository shows it can also run custom agents and schedule automated tasks. Users can point it at local notes, PDFs, or markdown files and query them in natural language. The website lists integration with chat interfaces and a plugin for Obsidian. Khoj is open source under the AGPL license, and the GitHub repository has accumulated 36,068 stars.

Key capabilities documented include:

• Answering questions from uploaded documents (and optionally the web).
• Building and running custom AI agents for repeated workflows.
• Scheduling automated actions (e.g., daily digest, content summarization).
• Self-hosting on a personal server or local machine.

Who is Khoj for?

According to the project documentation, Khoj targets individuals who want a private, personal AI assistant that knows their data. It suits people who maintain large collections of notes, research papers, or technical documentation and want to query them conversationally. The self‑hosting requirement means users need some comfort with Docker or Python setup. The scheduling and agent features also appeal to users who want to automate recurring information‑gathering tasks. The docs do not target enterprise teams as a primary audience; the focus is on a personal second brain.
