Tag Extractor
ProPaste a competitor's video URL and see the tags they used. This needs a live YouTube data connection, so it's launching with GameTagGen Pro rather than the free tier.

Why this one's Pro-only
Every other tool on GameTagGen runs entirely in your browser — no server, no API cost, free forever. Reading another creator's tags requires calling the YouTube Data API on their video, which has a real per-request cost, so it's scoped to Pro rather than bundled into the free tier.
Until it ships, the YouTube Tag Generator is the fastest way to build your own tag set from scratch.
