アニメ is an animation medium from Japan. The term itself has a pretty vague definition, so I’m relying on aniDB‘s definition, just that I don’t consider animation from Korea or China to be ‘anime’^A).
Anime separates itself from Western animation in several ways…but attempting to describe the differences comes off as pretentious, so I won’t bother.

• aniDB
  • AniDB is a database of CJK animation. It has a vast amount of information on anime, so it’s a good source for looking for all kinds of information. The interface is outdated and cumbersome to navigate unfortunately. You can set up an account on aniDB to keep track of what you watch, but using it is complicated.
• AniList
  • AniList is a more ‘casual’ source for information on anime (and Manga), but it’s decent for finding content and some basic information. You can also set up an account to track content here.
