Lots of podcasts and lesson transcripts for various Korean levels. Somewhat spammy marketing, but solid content which I’ve been using for years.

Hands down, the best dictionary for Korean learners is Naver Dictionary. If you download the app, you’ll get awesome content like videos, dialogues, Kpop content, daily phrases and more. You can also use the mobile website if you prefer. It’s pretty robust and is clearly geared at Korean learners.
Naver also has a translator called Papago. You can use the audio feature to listen to a native pronunciation. It’s awesome!
