I have peer-reviewed research on the efficacy of SRS in second-language acquisition and this should be everywhere for everyone and the fact that it isn't is both a scandal and an opportunity for learners who do use it to leverage that advantage.

I use it extensively in my teaching. The problem is deploying Anki on locked down networks can be difficult so I've built alternatives and hacks to let you deploy decks and school accounts, but making a full-featured web client would change all of this.

So maybe it's a good time for me to have also started one of my own that I'm temporarily calling libreSRS because I'm not sure of the new direction here.

The goal is to have a multi-user, multi-algorithm-capable, web-based system that exposes everything (especially uploading!!) to the web client.
