Khoj

Khoj is an AI search tool. Open source AI second brain for chatting across your documents and the web, with reusable agents and scheduled automations. Aimed at researchers and technically comfortable users who value transparency and model choice over a fully managed hosted service.

Khoj is an open source assistant that the team behind it calls an AI second brain. Rather than a single-purpose chatbot, it is a workspace where you build agents, schedule recurring automations, and run research across your own documents and the open web from one chat interface. The stated goal is to turn any AI model into a personal assistant, so the product is designed around model choice rather than locking you to one vendor. The everyday experience is conversational. You ask a question, and Khoj draws on indexed material (your notes and files) plus web search to answer it, so the same chat window handles both "what did I write about this last year" and "what is the current state of this topic online." Agents let you save a configured setup and reuse it, and scheduled automations mean a research or summary job can run on a cadence instead of waiting for you to prompt it by hand. It suits researchers, writers and knowledge workers who accumulate a large personal archive and want to query it in plain language, and it suits technically comfortable users who care about running things on their own terms. The code is public on GitHub, which matters for anyone who needs to inspect how the tool works or host it themselves rather than trusting a black box. Khoj sits alongside hosted chat assistants and note-app AI features, but positions itself on openness and on the combination of agents, automation and document research in one place. The homepage gives no published pricing tiers, integration list or support terms, so those details need checking on the project itself before committing. It is best treated as a tool for people willing to spend a little time on setup in exchange for transparency and control.
