Setup

• Make sure python and pip are installed on your machine

• khoj.el attempts to automatically install, start and configure the khoj server. If this fails, follow these instructions to manually setup the khoj server.

Direct Install

M-x package-install khoj

Minimal Install

Add below snippet to your Emacs config file. Indexes your org-agenda files, by default.

  ;; Install Khoj Package from MELPA Stable
  (use-package khoj
    :ensure t
    :pin melpa-stable
    :bind ("C-c s" . 'khoj))

• Note: Install khoj.el from MELPA (instead of MELPA Stable) if you installed the pre-release version of khoj
  • That is, use :pin melpa to install khoj.el in above snippet if khoj server was installed with --pre flag, i.e pip install --pre khoj-assistant
  • Else use :pin melpa-stable to install khoj.el in above snippet if khoj was installed with pip install khoj-assistant
  • This ensures both khoj.el and khoj app are from the same version (git tagged or latest)

Standard Install

Add below snippet to your Emacs config file. Indexes the specified org files, directories. Sets up OpenAI API key for Khoj Chat

;; Install Khoj Package from MELPA Stable

  :ensure t
  :pin melpa-stable
  :bind ("C-c s" . 'khoj)
  :config (setq khoj-org-directories '("~/docs/org-roam" "~/docs/notes")
                khoj-org-files '("~/docs/todo.org" "~/docs/work.org")
                khoj-openai-api-key "YOUR_OPENAI_API_KEY")) ; required to enable chat

Add below snippet to your Emacs config file. Indexes the specified org files, directories. Sets up OpenAI API key for Khoj Chat

  ;; Install Khoj Package using Straight.el
  (use-package khoj
    :after org
    :straight (khoj :type git :host github :repo "khoj-ai/khoj" :files (:defaults "src/interface/emacs/khoj.el"))
    :bind ("C-c s" . 'khoj)
    :config (setq khoj-org-directories '("~/docs/org-roam" "~/docs/notes")
                  khoj-org-files '("~/docs/todo.org" "~/docs/work.org")
                  khoj-openai-api-key "YOUR_OPENAI_API_KEY" ; required to enable chat)

Use

Search

1. Hit C-c s s (or M-x khoj RET s) to open khoj search

2. Enter your query in natural language

e.g "What is the meaning of life?", "My life goals for 2023"

1. Hit C-c s c (or M-x khoj RET c) to open khoj chat

2. Ask questions in a natural, conversational style

See Khoj Chat for more details

Find Similar Entries

This feature finds entries similar to the one you are currently on.

1. Move cursor to the org-mode entry, markdown section or text paragraph you want to find similar entries for
2. Hit C-c s f (or M-x khoj RET f) to find similar entries

Advanced Usage

• Add query filters during search to narrow down results further

  e.g What is the meaning of life? -"god" +"none" dt>"last week"

• Use C-c C-o 2 to open the current result at cursor in its source org file

  • This calls M-x org-open-at-point on the current entry and opens the second link in the entry.
  • The second link is the entries org-id, if set, or the heading text. The first link is the line number of the entry in the source file. This link is less robust to file changes.
  • Note: If you have speed keys enabled, o 2 will also work

Khoj Menu

Hit C-c s (or M-x khoj) to open the khoj menu above. Then:

• Hit t until you preferred content type is selected in the khoj menu

  Content Type specifies the content to perform Search, Update or Find Similar actions on

• Hit n twice and then enter number of results you want to see

  Results Count is used by the Search and Find Similar actions

• Hit -f u to force update the khoj content index

  The Force Update switch is only used by the Update action
