Gnosis (γνῶσις), pronounced “noh-sis”, meaning knowledge in Greek, is a Spaced Repetition System (SRS) for note taking and self testing.



Gnosis is a spaced repetition note taking and self testing system, where notes are taken in a Question/Answer/Explanation format & reviewed in spaced intervals.

Gnosis can help you better understand and retain the material by encouraging active engagement. It also provides a clear structure for your notes & review sessions.

Currently there are 2 ways for editing notes:

  • You can edit a note after review by pressing e
  • Open gnosis-dashboard with M-x gnosis-dashboard, find the note you want to edit and press e

Sync between devices

Gnosis uses git to maintain data integrity and facilitate synchronization of it’s database across devices.

You can set a git remote manually:

cd ~/.emacs.d/gnosis # default location for gnosis
git init # After completing your first review session, a git repo should have been initialized automatically.
git remote add <remote_name> <remote_url>
git push --set-upstream origin master

You can interactively use gnosis-vc-push & gnosis-vc-pull. As the name suggests, they rely on vc to work properly.

Depending on your setup, vc might require an external package for the ssh passphrase dialog, such as x11-ssh-askpass.

To automatically push changes after a review session, add this to your configuration:

(setf gnosis-vc-auto-push t)
(gnosis-vc-pull) ;; Run vc-pull for gnosis on startup
