Language Learning with Flashcards in the ATmosphere

December 20, 2025

I've been loving all the new apps that have started to emerge in the at-protocol ecosystem, now there isn't just BlueSky but also

  • https://tangled.org/

  • https://www.flashes.blue/

  • https://atcr.io/

  • https://leaflet.pub/home

and there is probably even more awesome things being build that I am not even aware of yet. Seeing all this momentum build up got me thinking about the kind of thing I would like to exist based on the at-protocol and what I ended up with is a language learning app similar to Anki where each user can create their own decks of flashcards and share them with others.

This idea still in an early infancy stage. I have recently asked around Bluesky to see if anyone is already building something in a similar direction.

Is anyone building a language learning app on the atprotocol already? 🤔

What I found was which looks great but seems to be more focused on tracking your language learning efforts and habits rather than offering you a way to actively study a language.

There's a lot of open question for this, mostly where the actual decks would be stored, on the PDS? Or would it be something like atcr is doing for container images?

I will need to spend some more time thinking this through but if you are interested and have ideas or already building something similar please do reach out.
