What does YouTube Channel Research do?
Batch-research the latest 1–N videos of a YouTube channel and produce ONE cross-video comparative report (not N isolated summaries) — enumerate uploads, fetch text with captions first and local ASR as fallback, then write up themes, drift, contradictions and limits. Trigger phrases: 研究这个YouTube频道, 频道最近的视频, 批量总结YouTube, youtube频道调研, 这个频道最近N个视频讲了什么, 频道内容分析, 竞品频道追踪, youtube 批量字幕/转录, youtube channel research, latest videos
