Finding content that's understandable as a beginner is one of the first challenges you'll face. Here are the main options:
Many creators make content specifically designed for language learners — slow, clear speech with visual aids and limited vocabulary. Search YouTube for "[your language] comprehensible input" to find these. They're the easiest starting point for immersion.
There's a Comprehensible Input Wiki with lists of input sources for over 70 languages. It's incredibly useful.
Movies and TV shows you already know, dubbed into the target language. Because you already know the story, the language is much more comprehensible. Disney movies, popular animated films, and well-known TV series often have high-quality dubs, many with subtitles.
If they don't have subtitles, or they don't match the audio, AI transcription has come a long way and can produce accurate subtitles (for dozens of languages) for free or very cheap.
Shows and books made for young native speakers use simpler language. They're not always the most engaging for adults, but they're fully natural language at an accessible level.
Books, podcasts, and videos designed for specific proficiency levels (A1, A2, etc.). These are useful but can feel artificial or boring since they're designed to be easy rather than entertaining.
The most common type of this are graded readers, but there are a few other options, often created by schools or governments. They're basically the same as the Comprehensible Input genre.
Finding resources can be one of the most challenging parts of the learning process... Unless someone's already done the hard work for you! Over the past several years, Refolders of dozens of languages have been collecting and documenting their favorite resources.
