tbh if you just use the free version of duolingo i don’t think you can do many lessons now, the energy runs out after like 2-3 lessons max
im learning french so i use it just as a daily reminder to do something in french but outside of it, there should be loads of music and podcasts and audiobooks on spotify that you can use, i can’t be specific but there is things like news in slow french that surely must exist for spanish
if you have a decent video card with 8gb vram can look into lm studio with eurollm and run your own chatbot locally
can say things like, i am an a1 spanish learner, give me a word in English to translate to spanish and tell me if i get it right or wrong
give me a sentence in spanish to translate into english etc
mistral.ai is your best bet if you want something online, they are a french company but do a lot with european languages
hellotalk is good if you want to listen in on people learning to speak but the quality of audio depends on the persons mic quality so might be better for later in learning journey
there’s tons of stuff, best is usually just to seek out books/music/sites and do your best to spend as much of your day learning, the more time you do the faster you learn but it is tough! good luck!
