Working on a Rails FSRS app, similar focus on healthy defaults, trying to find the 80/20 of what Anki does today: https://cadence.cards, free side project.

I’d like to have deck-wide variables/lookup tables and links.

The decks for studying Japanese that I’d like would have RTK/wanikani style elements used for mnemonics and I’d like them shown in the answer along with a full description and cross references.

Right now I’d have to build a templating system to prebuilt my deck and import it and it’s just a lot of work on top of the work of building the content, but mostly it makes it difficult to edit/update cards while studying.

I've been doing spaced repetition in plain text (org files in Emacs) for 7 years now.

org-drill is the original main package, but the newer org-srs is probably better (and supports FSRS).

As Hinton said during an podcast, humans can only learn at the rate of few bits per second. Memory and natural language are of very limited bandwidth.

> Your performance and review history is stored in an SQLite database in the same directory as the cards.

Do you use Syncthing or something else to sync your performance history between devices?

For anyone who prefers reviewing their cards via their phones, this appears to work very nicely on Termux

All my notes are in latex.

Any way to use them, or do I have to go through markdown format?

This looks awesome, I'm looking forward to trying it

Ok but what about images and formulas?

Obligatory mention of Obsidian’s most popular spaced repetition plugin: https://github.com/st3v3nmw/obsidian-spaced-repetition

It has the least friction for creating flashcards I’ve ever seen. You actually don’t even have to create flashcards - you can add any note to the review queue with one keystroke and record the ease of recall with another command.
