# tube.jic.io — JIC Long-form (长片): a curated catalog of lectures, courses, documentaries and explainers

> Part of JIC. Index of all JIC sites: https://jic.io/llms.txt · 中文: https://tube.jic.io/llms-zh.txt

tube.jic.io lists long videos that human communities kept recommending over years, ranked by how many separate months they were recommended in, not by views. Short videos live on v.jic.io; this site is for things worth watching whole, 20 minutes to 3 hours.
The first batch is the full HackerTube dataset: 6,454 YouTube videos linked in Hacker News comments 2007–2026, each by at least 3 people in at least 3 different months, with AI-written cards (summary, why HN recommends it, type, level, shelf life) and 150 topics in 16 areas. Chinese titles and summaries are added by JIC. Playback uses YouTube's privacy-enhanced embed; nothing is re-hosted.
