They Said Buy is an independent project that creates a public, dated record of stock recommendations made by investing YouTubers. The platform collects statements from public videos, links them to the exact moment they were spoken, and tracks the share-price movements that followed. Its core purpose is to give viewers a way to revisit an investment idea after the video has disappeared from their feed. By preserving the original words and context, the site helps users distinguish between a casual mention, a named pick, and a disclosed holding. This paper trail turns fleeting YouTube commentary into a permanent, checkable reference point.
