Existing AI tools often lack the ability to leverage personal data effectively or offer sufficient user control over data privacy and AI behavior. Khoj addresses this by providing a self-hostable platform to query personal information, build custom agents, and integrate with various LLMs, offering autonomy and control.
Core Features
Unified Search
Get answers from both your local documents (notes, PDFs, code) and the web simultaneously.
Custom AI Agents
Build and deploy specialized AI agents tailored to specific tasks or information sources.
LLM Versatility
Works with any online or local LLM, including GPT, Claude, Gemini, Llama, Qwen, Mistral, and more.
Automation & Research
Schedule tasks, automate workflows, and perform deep, autonomous research based on your requirements.
Self-Hostable & Private
Run Khoj on your own infrastructure, ensuring data privacy and complete control.
Tech Stack
