13 Org-roam Completion System

Org-roam allows customization of which minibuffer completion system to use for its interactive commands. The default setting uses Emacs’ standard completing-read mechanism.

(setq org-roam-completion-system 'default)

If you have installed Helm or Ivy, and have their modes enabled, under the 'default setting they will be used.

In the rare scenario where you use Ivy globally, but prefer Helm for org-roam commands, set:

(setq org-roam-completion-system 'helm)

Other options include 'ido, and 'ivy.
