For the past couple of years, I've used LLMs for helping me creating flashcards -- and loved it. Initially, I built a very simple desktop tool that would send the LLMs output to a Google spreadsheet, from where Flashcards (an iOS app, [1]) would import them as decks.

After a year or so, I wrapped it up in a Telegram bot, so I could just send a new card or phrase to it, and it would take care of translation, pronunciation, and usage examples. As I'm usually learning several languages in parallel, I also added the automatic language detection (from preselected languages).

Then I randomly found out that FSRS is better than SM2 (which Flashcards uses), and found an Elixir library that implements that. So, I decided to drop both spreadsheets and the Flashcards app, and implement the review process right in my bot.

This is how I ended up with https://lexicorn.ai -- just got my first paying subscriber (yay, I guess). The site doesn't say it, but it's 5 euros/month.
