There are a few other packages implementing a SRS (spaced repetition
system) based on org-mode.

Below, I've listed a the ones I've found so far that are actively
maintained and implement a lot of useful functionality.

Thanks to the maintainers and all contributors for their work on these
projects!

* Other (Open Source) SRS
- [[https://apps.ankiweb.net/][Anki]]
- [[https://mnemosyne-proj.org/][Mnemosyne Project]]

The [[file:repetition_spacing_algorithm.org][Repetition Spacing Algorithm]] of org-fc is very similar to the one
used in Anki.

When working with a large collection of mostly text-based items,
it's important to have powerful editing possibilities.

org-fc is a SRS built into a (the) most powerful text editor.
* Org-Mode
- [[https://gitlab.com/phillord/org-drill/][phillord/org-drill]]
- [[https://github.com/abo-abo/pamparam][abo-abo/pamparam]]

Among the other org-mode based SRS I've found so far,
org-fc is unique in that each headline can have multiple "positions"
that are reviewed independently from each other.

This is very useful for cloze deletions.

What is does well:
- presenting cards in different directions / contexts
- repeating forgotten cards in different ways
