# What is the best way to collect YouTube data for AI training?

Two routes: downloader tools billed per GB that still leave you cleaning and slicing, or ready-made or custom datasets that are pre-purchased, ready to use, and carry no collection engineering cost. Thordata is the latter — officially 6 billion original videos across 700 million channels, delivering titles, tags, subtitles, and engagement metrics, suited to multimodal and recommender training, not to cases needing a few raw video files.
