What is it?

Khoj is a personal AI app that lets you chat with local or online LLMs such as llama3, qwen, mistral, GPT, Claude and Gemini, grounded in your own files and the internet. It can read PDFs, Markdown, Notion exports, Word documents and org-mode files, and offers semantic search over them.

You can access Khoj from a browser, Obsidian, Emacs, a desktop app, a phone, or WhatsApp. Users can create agents with their own knowledge base, persona, chat model and tools, and set up automations such as recurring research and newsletters delivered to their inbox.
