16 areas · 150 categories
Browse Every HackerTube Topic
Move from broad areas to specific subjects, then open the matching videos in the directory. The three largest technical areas also have editorial guides that connect categories, videos and focused watch paths.
How the topic map works
The public snapshot groups 6,454 videos into 150 categories and 16 broader areas. Select a category to return to the video directory with that filter already applied. Categories can overlap, so one video may contribute to more than one area count.
Choose a useful starting point
Use the full directory when you already know the subject. For AI, software and mathematics, the editorial guides explain how the subtopics connect before suggesting a short, ordered watch path.
Topic labels, summaries and levels come from the public export and include model-generated fields. They are useful navigation clues, not a fixed academic taxonomy. Check the video and source discussion when a boundary or label matters.
