Auto translated flashcards for language learning

I don't think I'm going to pursue this one so figure I'd just share it.

Language learners LOVE flash cards. This idea is to allow users to choose a language they want to learn and enter a list of words and phrases. Then the application will translate all the phrases the user input into the language they want to learn and create flash cards from them (front = input text, back = translated text).

The benefit is users will be able to study particular words/sentences they want to study, as well as they can format sentences in the way they normally speak, in order for the translations to resonate better with them.

Building this application is actually really simple. deepl.com provides a simple API for translating text to a chosen language, at just $25/million characters after a generous free tier. Just take in the array of text inputs, translate them with DeepL, save it to your DB, and then render out a front/back UI showing all the tranlsations.

Marketing: Reddit /r/languagelearners LOVES flashcards, I'm sure they'd jump on it. Otherwise, you can start generating flash card decks yourself for various languages and try to get the SEO traffic since keywords like "Spanish flash cards" gets a lot of searches a month.
