Overzicht

Khoj is an open-source personal AI assistant designed to help you find, organize, and interact with your own knowledge base. It connects to local files, notes, PDFs, and online sources, letting you query them through natural language chat or semantic search. The tool can run locally for privacy or be used via a hosted version, and supports multiple LLM backends including open-source and commercial models. Beyond search, Khoj can summarize documents, generate images, browse the web, and act as a long-term conversational companion that remembers context across sessions. It is geared toward researchers, writers, developers, and knowledge workers who want a customizable AI layer over their personal data without sending everything to a third-party service.

Skeptical, then convinced

I went in skeptical — most tools in this space overpromise. It actually delivers on support for PDFs, Markdown, and plain text, and works with personal files and notes caught me off guard. Quality depends on chosen LLM is why this isn't a perfect score, still, I'd recommend giving it a real trial.

Compared a few options

Evaluated this against two competitors. Where it wins: conversational chat with memory and works with personal files and notes. On balance the feature set — especially local or cloud deployment options — justifies the 5 stars for our use case.

Solid for our team

We rolled this out across the team last quarter and supports multiple LLM providers. Conversational chat with memory fits neatly into how we already work, and semantic search across local documents removed a step we used to do by hand. Quality depends on chosen LLM, which is the main caveat, but it has held up under daily use.

Does the job

Pretty happy overall. Integrations with Obsidian, Emacs, and Notion just works and combines chat, search, and web browsing. Quality depends on chosen LLM can be annoying, but no dealbreakers — I'd recommend it to a friend without hesitating.
