When I was learning German, I used an app named Anki, which I recommend to anyone learning a language. It offers a quick method to aquire new vocabulary.
Besides vocabulary, learning a language comes down to using it.
Media like books, audiobooks, podcasts, and more offer so many opportunities to practice the language in a passive way.
AI tools like ChatGPT, Perplexity, Grok, and more offer opportunities to practice writing.
Here I am aiming to offer the ideal compliment to such tools -- a community where the language is used playfully and with care.
