I created a page that indexes Japanese news articles, YouTube videos (and some syosetu novels) by difficulty and JLPT level.
Currently at ~43.5k articles, ~4.4k videos, and 700 syosetsu novels indexed.
I'd appreciate any feedback, although there are a few issues I know about.

I've been working on this project for ~7 years — first for my Bachelor's degree, then my Master's, and eventually just because I genuinely liked the idea.
I created a Chrome extension that adds a popup dictionary to YouTube and Japanese websites.
It tracks the vocabulary you look up and lets you save it into decks to study later with built-in flashcards, print out, or export to Anki.
It tracks all the vocabulary you look up and lets you import it into a deck and either learn with the built-in flashcards app, print out, or export to Anki.
You can also mark words as New, Seen, Familiar, Known, or Mastered, and the extension then highlights them accordingly around the web. It also tracks the kanji you know automatically based on the vocabulary you’ve learned.
I'm also working on an introductory grammar/language course to make it easier to start reading Japanese earlier.
Most features are free (AI-related features cost money because of API costs).
Would love to hear what other Japanese learners think: lingaku.com
