Setup

These are the general setup instructions for Khoj.

• Make sure python and pip are installed on your machine
• Check the Khoj Emacs docs to setup Khoj with Emacs
  Its simpler as it can skip the server install, run and configure step below.
• Check the Khoj Obsidian docs to setup Khoj with Obsidian
  Its simpler as it can skip the configure step below.

1. Install

1.1 Local Server Setup

Run the following command in your terminal to install the Khoj backend.

• On Linux/MacOS

  python -m pip install khoj-assistant
  

• On Windows

  py -m pip install khoj-assistant
  

For more detailed Windows installation and troubleshooting, see Windows Install.

1.1.1 Local Server Start

Run the following command from your terminal to start the Khoj backend and open Khoj in your browser.

khoj

Khoj should now be running at http://localhost:42110. You can see the web UI in your browser.

Note: To start Khoj automatically in the background use Task scheduler on Windows or Cron on Mac, Linux (e.g with @reboot khoj)

1.2 Local Docker Setup

Use the sample docker-compose in Github to run Khoj in Docker. To start the container, run the following command in the same directory as the docker-compose.yml file. You'll have to configure the mounted directories to match your local knowledge base.

docker-compose up

Khoj should now be running at http://localhost:42110. You can see the web UI in your browser.

1.2 Select files for indexing using the desktop client [Optional]

You can use our desktop executables to select file paths and folders to index. You can simply select the folders or files, and they'll be automatically uploaded to the server. Once you specify a file or file path, you don't need to update the configuration again; it will grab any data diffs dynamically over time. This part is currently optional, but may make setup and configuration slightly easier. It removes the need for setting up custom file paths for your Khoj data configurations.

To download the desktop client, go to https://download.khoj.dev and the correct executable for your OS will automatically start downloading. Once downloaded, you can configure your folders for indexing using the settings tab. To set your chat configuration, you'll have to use the web interface for the Khoj server you setup in the previous step.

1.3 Use (deprecated) desktop builds

Before v0.11.4, we had self-contained desktop builds that included both the server and the client. These were difficult to maintain, but are still available as part of earlier releases. To find setup instructions, see here:

• Desktop Installation
• Windows Installation

2. Configure

1. Set File, Folder and hit Save in each Plugins you want to enable for Search on the Khoj config page
2. Add your OpenAI API key to Chat Feature settings if you want to use Chat
3. Click Configure and wait. The app will download ML models and index the content for search and (optionally) chat

3. Install Interface Plugins (Optional)

Khoj exposes a web interface to search, chat and configure by default.
The optional steps below allow using Khoj from within an existing application like Obsidian or Emacs.

• Khoj Obsidian:
  Install the Khoj Obsidian plugin

• Khoj Emacs:
  Install khoj.el

Troubleshoot

Install fails while building Tokenizer dependency

• Details: pip install khoj-assistant fails while building the tokenizers dependency. Complains about Rust.
• Fix: Install Rust to build the tokenizers package. For example on Mac run:

  brew install rustup
  rustup-init
  source ~/.cargo/env
  

• Refer: Issue with Fix for more details

Search starts giving wonky results

• Fix: Open /api/update?force=true in browser to regenerate index from scratch
• Note: This is a fix for when you perceive the search results have degraded. Not if you think they've always given wonky results

Khoj in Docker errors out with "Killed" in error message

• Fix: Increase RAM available to Docker Containers in Docker Settings
• Refer: StackOverflow Solution, Configure Resources on Docker for Mac

Khoj errors out complaining about Tensors mismatch or null

• Mitigation: Disable image search using the desktop GUI
